Saka hezvino taenda. Tora kofi. Kana doro. handisi kutonga.
Kurumidza chaiko tisati tatanga- kwandakabva kubvira vanhu vachigara vachibvunza kuti: Ndanga ndichiita bishi nebhatiri tech kubva 2016, ndakashandira makambani maviri akashaya mari (nguva dzinonakidza), ndakabvunza vatatu vachiri vapenyu (zvishoma), uye parizvino vari kuita R&D ye... zvakanaka handifanire kutaura asi iwe wakanzwa nezvavo. Ndakazvipisa nemoto welithium kaviri. Usaikurudzire. 0/10 chiitiko.
What the Hell Even IS a Solid-State Battery?
Ndizvozvo. Batiri refoni yako? Laptop? Motokari yemagetsi? Zvese zvine mvura mukati. Hazvina kufanana nemvura-mumvura, zvakanyanya se... mvura yemakemikari yakakora. Organic electrolyte. Inonzwika seyakanaka asi inobvira goo inoita kuti lithium ions ishambidze nekudzoka pakati pemativi akanaka neasina kunaka.
Inoshanda zvakanaka! Kusvikira hazviiti. Inobva yabata moto.
Ndichine Samsung Galaxy Note 7 mudhirowa rangu redhesiki randinochengeta sechiyeuchidzo lmao. Handina kuzomboibatidza zvakare mushure mekurangarira. Zvakafanana nekamoto kadiki paperweight.
Rakasimba-bhatiri renyika=richitsiva mvura iyoyo nerota.
Ndizvo. Ndicho chinhu chose.
Chikamu chakasimba chinogona kuva:
Ceramic zvinhu (segirazi rakanaka asi rakaoma kugadzira)
Polymer cheni (funga chaizvo gobvu plastiki asi kwete chaizvo plastiki)
Sulfide makomisheni (aya anonhuwa ZVINOTYISA nenzira, kunge mazai akaora kakapetwa chiuru)
Chokwadi chinonakidza Ndakadzidza zvakaoma - zvimwe zvezvinhu izvi zvinoita kana paine mwando mumhepo. Kuda zvechisimba. Taive nemudzidzi wegiredhi muna 2019 akasiya sulfide electrolyte sample pabhenji husiku. Mangwanani akatevera, zvinhu zvose zvakanga zvaora. Ainhuwa kunge rufu. Hatina kukwanisa kushandisa lab iyoyo kwevhiki.
Sei Munhu wese Asinganyarara Nezvavo
Hama ndanga ndichinzwa nezvemabhatiri akasimba-kubva... 2015? 2014? Kumwe kwakapoteredza uko. Gore rega rega: "Makore matatu chete!"
Yave meme munharaunda yebhatiri. Kufanana nesimba rekubatanidza. Nguva dzose 10 makore kure.
Asi zvakanaka pane zvikonzero chaizvo zvekutarisira:
1. Izvo (zvichida) hazvizoputika muchiso chako
Hapana mvura=hapana mvura inofashaira=hapana pressure buildup=hapana boom.
Ndinoreva kuti ivo vachiri kukundikana. Ndakazviona zvichiitika. Asi panzvimbo yebhora remoto unowana zvakanyanya se ... inomira kushanda uye inodziya. Zviri nani! Ndakaona chimiro chakasimba-chakakundikana panguva yekuyedzwa gore rapfuura uye chakangozvimba zvishoma ndokufa. Ne liquid lithium-ion tinofanira kuyedza kuseri kwe blast shield. Different vibe.
2. Simba rakawanda munzvimbo imwechete (zvichida)
Zvekunzi ndezvemusango. 50% zvimwe? 100% zvimwe? Ndiani anoziva. Pabepa masvomhu anoshanda. Chaizvoizvo? Tichaona.
Toyota inoramba ichiti vachange vaine mabhatiri e900-mamaira panosvika 2027 kana 2028 kana chimwe chinhu. Ndichazvitenda kana ndave kutyaira mota chaiko. Kusvika ipapo yave vaporware.
3. Kuchaja nekukurumidza (pamwe)
Mamwe eceramic electrolytes anogona kunge achibata nzira yazvino pasina kusvibisa. Saka semaminetsi gumi akazara kuchaja.
Ndakaona basa iri murabhoritari? Hongu, kamwe, pabheteri resimbi saizi yechigunwe changu.
Ndaona ichishanda pa-bhatiri remota? Kwete. Hapana ane. Yese idata rekuenzanisa uye zviyedzo zvidiki-.
4. Inogara kwenguva refu (tinofunga)
Pasina mvura kuputsika iwe unofanirwa kuwana mamwe machaji ekutenderera. Regular lithium-ion yakanakira sema 500-1000 macycles zvichienderana nemabatiro aunoita. Solid-state inofanira kuita zvirinani.
Asi hechino chinhu - chatisati TICHAZIVA nekuti hapana anga ava nemakore gumi achidzishandisa. Haikwanise kuyedza-nguva yakareba kuvimbika murabhoritari. Unofanira kungomirira uone.
Mirira Chii chatiri Kufananidza Izvi Ne?
Ah crap hongu ndinofanira kutsanangura zviri kunze uko zvino. Wakaipa wangu.
Regular Lithium-Ion (Zviri Muzvose)
Foni yako, laptop, pamwe mota yako kana iri yemagetsi
Simba: ~250-300 Wh/kg (ndiyo maawa ewatt pakg pakirogiramu, mayunitsi emagetsi)
Yakachipa kugadzira izvozvi nekuti tanga tichizviita zvachose
Ichabata moto zvachose kana ukaiboora kana kuwedzeresa
Ndinochengeta bhakiti rejecha murabhoritari yangu kana zvichiita
LFP Mabhatiri (Lithium Iron Phosphate)
Yakachengeteka, haizobati moto kunyangwe ukaedza
Kuderera kwesimba kunosvika - kunosvika 160-180 Wh/kg
Inogara NEkusingaperi se 3000+ machaji
Yakachipa kupfuura mamwe marudzi e lithium
Izvi ndizvo zviri mu base modhi yaTesla ikozvino yandinofunga? Usanditore pazvo
NMC/NCA (Idzo Dzinodhura)
Nickel Manganese Cobalt kana Nickel Cobalt Aluminium
Kuita kwepamusoro, 250-280 Wh/kg
Anoshandisa cobalt iyo...ehe kune nyaya dzebasa revana muCongo, mamwe madhiri
Zvimwe zvinodhura
Kuita kurinani asi kwete kunyepa
Yakasimba-Nyika (The Mythical Creature)
MASHOKO 400-500 Wh/kg
Way way way inodhura izvozvi
Kugadzira ndeye black magic panguva ino
Zvakachengeteka zvinofungidzirwa asi zvakare hatina data rakakwana
Zvakanaka Asi Chii Chaizvo Chakanaka Pavari?
Tarisa handina chokwadi nezvezvinhu zvakawanda asi solid-state ine zvakanakira chaizvo. Not gonna kunyepedzera zvimwe.
Kuchengetedzeka kuri nani.
Ini pachangu ndakaedza mhando mbiri. Nenguva dzose lithium-ion tinopfeka nhovo dzechiso uye tine zvekudzimisa moto kwese kwese. Nezvimiro-zvakasimba? Zvichiri kungwarira asi zvishoma "izvi zvinogona kuputika" simba.
Mwedzi wapera takaita test cell short circuit. Zvakasimba-kuti munhu angopisa ndokumira kushanda. Dai yanga iri lithium yenguva dzose-ion tingadai takave nemoto chokwadi.
Saizi / huremu chinhu chaicho KANA vakaunza.
400 Wh/kg mukugadzirwa kwaizove kwechokwadi shanduko. EV bhatiri rako rinogona kurema hafu yehuwandu hwehuwandu hwakafanana. KANA huremu hwakafanana, kaviri huwandu.
Asi iyo yakakura IF. Mibairo yeLab haishandure kuita kugadzirwa. Hehe, KAZHINJI havaturidzi.
Tembiricha kuita kunofanira kuva nani.
Solid electrolytes anoshanda pahupamhi tembiricha renji pane mvura. Bhatiri remota yako muChicago chando pa -20℃F? Zvinofanira kushanda zviri nani. Arizona chirimo pa120℃F? Zvakare zviri nani.
Kunyangwe nyaya inonakidza - mamwe maelectrolyte eceramic anotoda kuchengetwa AKADZIDZISWA kuti ashande zvakanaka. Saka unoda heater yebhatiri rako. Iyo inoshandisa simba. Mhando yekukunda chinangwa lol.
Hapana dendrites.
Izvi zviri mukati me baseball asi chero. Paunochaja mabhatiri eti lithium, diki simbi spikes dzinodaidzwa kuti dendrites dzinogona kukura kubva kune imwe electrode kuenda kune imwe. Pakupedzisira vanobaya nepakati peseparator uye pfupi dunhu bhatiri. Ndiwo mafiro anoita mabhatiri mazhinji elithium-ion.
Solid electrolytes inofanirwa kuvhara dendrites. Zvinhu zvakaoma, hazvigone kubaya. Mupfungwa.
Mukuita? Eh. Takaona dendrites achikura kuburikidza nemamwe ma electrolyte akasimba. Materials sainzi yakaoma.
Matambudziko Wese Anoregeredza (Asi ini handidi)
Zvakanaka sunga nekuti apa ndipo pandichatsamwisa vamwe vanhu.
Ivo havashande izvozvi.
Ndine hurombo! Ichokwadi! Mabhatiri mazhinji e"budiriro" akasimba-aunoverenga nezvawo mumapepanhau? Vanoshanda sema cycles gumi. Pamwe makumi mashanu kana uine rombo rakanaka. Mune yakakwana lab mamiriro. Pa 25℃chaiyo. Nekamhepo kanofefetera kubva kuchamhembe kwakadziva kumabvazuva.
Bhatiri remota yako rinoda kushanda 1000+ muchando muMinnesota muchando uye muTexas chirimo nepakati pese. Hatisati tamboswedera pachiyero.
Ndakanga ndiri kumusangano gore rapfuura (Battery Symposium muOrlando, Kurume 2024) uye ndakaona mharidzo kubva pakutanga ichiti mazana mashanu emacycles. Vakazoenda kumba kwavo. Ndokumbirawo ruzivo. Vakabva vanyarara chaiko. Zvinoratidza kuti iwo mazana mashanu ekutenderera aive pa 0.1C yekuchaja mwero nemaawa mana pakati pechaji. Hazvina maturo zvachose kune chaiwo maapplication.
Kugadzira idambudziko chairo.
Takapedza 30+ makore tichitsvaga kugadzira mabhatiri e lithium-iyoni yakachipa uye yakavimbika. Iwo mafekitari, midziyo, kutonga kwemhando - zvese zvakadhairirwa mukati.
Yakasimba-nyika? Kutanga kubva pakutanga.
Midziyo yakasiyana. Maitiro akasiyana. Different kukundikana modes. Zvinhu zvese zvakaoma.
Ndakataura nemumwe mukomana wekuQuantumScape mwedzi wapera (taive tose kubhawa repaairport, anga akuda madoro matatu, akawana chatty) akati dambudziko ravo guru harisi kana tekinoroji zvakare. Iri kutsvaga magadzirirwo e10,000 mabhatiri ese akafanana. Consistency pachikero KAKAOMA ZVAKANAKA.
Dambudziko re interface riri kuuraya munhu wese.
Iyi inyanzvi asi yakakosha: apo iyo yakasimba electrolyte inobata iyo yakasimba electrode, iwe unowana kuramba. Zvakafanana nekuedza kupfuudza magetsi munzvimbo mbiri dzakashata dzakatsikirirwa pamwechete. Kwete kuonana kukuru.
Ne electrolyte yemvura, iyo mvura inozadza ese microscopic gap. Perfect kuonana kwese. Nezvakasimba-pa-zvakasimba? Kwete zvakanyanya.
Vanhu vari kuyedza zvese: machira akakosha, kuisa kumanikidza, kudziyisa, zvishandiso zvitsva, zvibairo, nzvimbo dzebuffer. Hapana chinoshanda zvakakwana parizvino. Yese mhinduro inogadzira matambudziko matsva.
Vanotsemuka uye zvakaipa chaizvo.
Ceramic yakasimba electrolytes ine brittle. Kana mabhatiri achichaja, anozvimba zvishoma. Vanobuda, vanoderera. Ita izvi ka1000 uye ceramic yako inogona kutsemuka.
Kamwe kadiki kadiki=bhatiri rakafa. Kunyorova kunopinda, kuita kunodonha, mutambo wapera.
Ndakaona akasimba-masero ehurumende akashanda zvakanaka kwema 50 cycles, obva atsemuka, omira kushanda. Zvinorwadza moyo. Uye zvinodhura.
Polymer electrolytes haitsemuke nyore nyore asi ine nzira yakaderera ionic conductivity. Garai muchitengesera-zvinobvamo.
Mari yacho inoita kuti ndide kuchema.
Zvinofungidzirwa zvazvino zvinoita kuti mabhatiri akasimba-enyika akwire pa10-20x mutengo welithium-ion yenguva dzose. Per kWh.
Ehe mari dzichadzika nechiyero. Vanogara vachidaro. Asi isu tiri kutaura MAKORE ebudiriro uye MABILIONI mukudyara kukuru tisati tasvika pamutengo wakaenzana.
Tesla's 4680 maseru anodhura se $100/kWh. Yakasimba-nyika inogona kuita $1000/kWh izvozvi. Pamwe zvimwe. Hapana anoburitsa nhamba chaidzo nekuti dzinonyadzisa.
Ndiani Chaizvo Ari Kugadzira Zvinhu Izvi? (Uye Ndiani Ari Kungotaura Nezvo)
Ah murume zvakanaka izvi zvichanetsa nekuti pane senge 50+ makambani arikuti "ave kuda kushandura mabhatiri" asi regai nditarise kuti ndiani ari kuita zvinhu:
QuantumScape- Pamwe ichiri kure kunezvekushandisa zvemotokari. Kushandisa ceramic separator. Inotsigirwa naVW naBill Gates. Mari yavo yakabva pamadhora zana nemakumi matatu kusvika pamadhora gumi. Ouch. Asi vachiri kushanda uye varatidza mimwe mhedzisiro yebvunzo yakanaka. Nguva inoramba ichitsvedza kunyangwe izvo zviri ... zvine chekuita asi zvakare ndezvechokwadi? Handizivi kuti ndonzwa sei pamusoro pavo pachokwadi.
Simba Rakasimba- BMW neFord dzakatsigirwa. Sulfid electrolyte. Pakupedzisira ndakanzwa kuti vakanga vachiri nenyaya dzekugadzira. Nguva yavo yakatsvedza zvakare. Nguva yemunhu wese inotsvedza. Ndiko kunakidzwa neindasitiri yemabhatiri.
Samsung SDI- Vane mabhatiri akasimba-ari mukugadzirwa! Asi zvidiki. Zvekupfeka. Zvishandiso zvekurapa. Zvinonzwika (hongu ndiro izwi zvino sezviri pachena). Motokari-zvinhu zvakakura? Ndichiri mubudiriro. Vanoti 2027. Ini ndinoti 2029-2030 chokwadi.
Toyota- Ah mukomana. Toyota yanga ichivimbisa-mabhatiri ebudiriro kubvira ndisati ndatanga kushanda munzvimbo ino. Vanoisa mapepa akawanda kupfuura chero ani zvake. Vanoita zviziviso zvikuru gore negore. Uye zvakadaro ... hapana zvigadzirwa.
NDINODA kuvatenda. Ndivo Toyota. Vanoziva kugadzira. Asi chimbondinyengerera, shame on you. Ndinyengedze ka47...
Ivo vakati 2025, ipapo 2027, ikozvino 2027-2028. Ndichaisa mari pa2030 shoma.
Nissan- Kunyarara nezvazvo izvo zvandinoremekedza. Iti vachave nekugadzirwa kwendege panosvika 2024-2025. Yakanyanya kuitika yenguva kupfuura vamwe. Kushanda neNASA pane zvimwe zvinhu zvandinofunga? Don't quote me.
CATL- Kambani yekuChina, inogadzira mabhatiri makuru pasi rose. Pavanofamba, munhu wese anoona. Vari kushanda nesimba-asi vachinyatso chengetedza nekufungidzira. Zvinoita kuti ndivavimbe zvakanyanya. Vanoziva chiyero chekugadzira. Vanoziva chakaoma.
StoreDot- Kutangisa kweIsrael, kutarisa kwekuchaja nekukurumidza. Cool demos. Kuyera ndiwo mubvunzo. Nguva dzose mubvunzo.
Kune zvakare Factorial Energy, ProLogium, Ionic Materials, Sakuu, Blue Current, Ilika... Vazhinji vachakundikana. Ndiwo mashandiro azvinoita. Mabhatiri ekutanga ane senge 5%.
Unogona Kutenga Imwe Parizvino?
Mhinduro pfupi:Aihwa.
Mhinduro refu:Zvakadaro kwete, kunze kwekunge iwe uri kutenga prototype EV yemadhora mazana mashanu emadhora + kana diki diki bhatiri rekushandisa zvekurapa.
Mhinduro yakareba:Samsung ine -mabhatiri ehurumende aripo asi anodhura uye madiki. Tiri kutaura kunge coin cell size. Hazvibatsiri kune akawanda maapplication.
Zvigadzirwa zvekutanga zvevatengi zvine-zvakasimba zvingangove:
Premium smartphones- Samsung kana Apple ichada kodzero dzekuzvitutumadza. "Chekutanga yakasimba-nhare yebhatiri!" Kushambadzira kukuru. Pamwe 2026-2027.
EVs yekugadzira yakaganhurirwa- Imwe mhando yemhando yepamusoro ichaita mazana mashanu mayunitsi ane -mabhatiri akasimba. Mutengo we $200k. Ratidza kuti tekinoroji inoshanda. 2027-2028.
High-end e{{1}mabhasikoro/mascooters- Bhatiri diki rinoita kuti zviwane muhupfumi. 2026?
Misika yakawanda? Murume wandisingazivi. 2030 kare. Pamwe 2032-2035 kuve akachengeteka. Uye kunyange ipapo "musika mukuru" unogona kureva "kusarudza kukwidziridzwa kwe $ 10k."
Ndinenge ndiri kusava netariro. Asi ndakaodzwa mwoyo kakawanda.
Chii Chaizvo Zvavachashandiswa?
Izvozvi? PowerPoint mharidzo kazhinji.
Asi seriously:
Motokari dzeMagetsi- Izvi ndizvo zvine hanya nemunhu wese. 500+ mamaira renji, maminetsi gumi achaja, akareruka, asina njodzi. Zvinganyatso shandura musika weEV. KANA zvikaitika.
Mafoni uye Laptops- Fungidzira foni yako ichitora mazuva maviri akazara uchishandisa zvakanyanya. Kana kuva hafu yeukobvu. Kana kusambove neSamsung Note 7 mamiriro zvakare. Ndidzo hope dzacho.
Mishonga Yezvokurapa- Apa ndipo pane mamwe mabhatiri akasimba-ari KARE ari kushandiswa! Mapacemaker anoda mabhatiri ayo 100% asingakundikane kana kudonha mukati memuviri wako. Solid-nyika yakanakira izvi. Bhatiri diki, haridi kuve rakachipa, chengetedzo ndizvo zvese.
Drones/Aviation- Ndege dzemagetsi dzinoda kuwandisa kwesimba kwakanyanya. Gramu imwe neimwe inokosha. Solid-nyika inogona kuita kuti ndege yemagetsi ishande kupfuura zvidhori zvidiki.
Grid Storage- Pamwe? Asi kutendeseka kwekuchengetedza kwakamira, uremu hauna basa. LFP yatove yakachipa uye yakachengeteka zvakakwana. Zvakaoma kurova pamutengo. Nyika yakasimba-inoda kuwana zvakachipa CHAIKO kuti ukwikwidze pano.
Unofanira Kumirira Nyika Yakasimba-Usati Watenga EV?
Ndinogara ndichibvunzwa izvi. Kumapati (mabhatiri mainjiniya anoenda kumapati zvakanaka), pamisangano, hama dzisina kurongeka paFacebook.
Mhinduro: Kwete. Usamirira.
Kana iwe uchida EV izvozvi, tenga EV izvozvi. MaEV azvino akanaka chaizvo! Model 3, Ioniq 5, F-150 Mheni, sarudzo dzese dzakasimba. Proven technology. Kuzivikanwa kuvimbika.
Panosvika nguva inokwanisika-nyika maEVs aripo:
Unenge watotyaira EV yako iripo kwemakore 5+
Tekinoroji icharamba iri yekutanga-chizvarwa chine zvinhu zvisingazivikanwe
Kuchaja zvivakwa zvichave nani
Yakashandiswa EV mitengo inogona kunge yadonha ndiani anoziva
Kana iwe uri kuronga kutenga mukupera kwa2027 kana 2028? Ipapo pamwe mirira kuti uone kuti chii chaizvo chinoburitswa. Asi usaisa hupenyu hwako pairi.
Tekinoroji inogara ichivandudza. Pane nguva dzose chimwe chinhu chiri nani chiri kuuya "nokukurumidza." Haikona kumirira zvachose.
Ndakamirira kutenga 4K TV kusvika 2019. Zivai zvakaitika? Vakawana zvakachipa uye zviri nani. Asi ini zvakare ndakanga ndisina 4K TV kwemakore matanhatu. Zvakanga zvakakodzera here? Honestly... kwete. Ndaifanira kungotenga imwe chete.
Iyo Energy Density Nhamba inhema (Marudzi E)
Okay kwete kunyepa. Asi kurasisa.
Wese munhu anokanda nhamba dzekusimba kwesimba. "400 Wh/kg!" "500 Wh/kg!" "900 Wh/kg!"
Hezvino zvavasiri kukuudza:
Iyezvino lithium-ion CELLS: 250-300 Wh / kg
Lithium -ion PACKS yazvino: 150-200 Wh / kg
Maona musiyano? Iyo paki inosanganisira casing, kutonhora, wiring, bhatiri manejimendi masisitimu. Kunge 30-40% yebhatiri pack uremu haina kana bhatiri.
Zvakasimba-zvichemo zveCELL: 400-500 Wh / kg
Yakasimba-nyika PACK chokwadi: Ndiani anoziva? 250-350 Wh/kg pamwe?
Saka kana Toyota ichiti "kaviri kuwanda kwesimba!" vari kuenzanisa-case cell number nenhamba dzepack dzazvino. Kwete maapuro kumaapuro.
Kuvandudza chaiko padanho repakeji kungangoita 50-75%. Izvo zvichiri zvakanaka! Chokwadi chikuru! Asi kwete shanduko yekushambadzira inoreva.
Zvakare simba density hazvisi zvese. Simba density zvine basa (kuti unoburitsa nekukurumidza sei). Hupenyu hwemabhasikoro hunokosha. Tembiricha kuita. Mutengo pakWh unonyanya kukosha pakutorwa kwevanhu vakawanda.
Bhatiri rinoita $2000/kWh rine 500 Wh/kg rakaipa kudarika bhatiri rinoita $100/kWh rine 250 Wh/kg. Zvemaapplication akawanda zvakadaro.
Zvangu Zvazvino Kurudziro
Kana iwe uri munhu wenguva dzose:Kanganwa-chimiro chiripo parizvino. Tenga chero chaunoda nehunyanzvi hwazvino. Inoshanda zvakanaka.
Kana iwe uri kutenga EV muna 2025-2026:Tenga izvozvi nelithium-ion iripo. Usamirira. Ramangwana rakakwana EV harisi kuuya nekukurumidza zvakakwana.
Kana iwe uri investor:Iyi injodzi huru, mubairo mukuru. Ini ndaibheja pane vatambi vakasimbiswa (Samsung, Toyota, CATL) pamusoro pekutanga. Asi ndini chete. Handisi pangozi-ndisingafariri nekuti ndaona matangi ebhatiri akawandisa achiparara nekutsva. Chaizvoizvo mune imwe nyaya.
Kana iwe uri injiniya:Pinda mumunda uyu! Zvinoshungurudza segehena asi zvinonakidza chaizvo. Ingo gadzirira kufambira mberi zvishoma nezvishoma uye yakawanda yakafa magumo.
Kana uri kuronga kutenga muna 2027-2028:Tanga kuterera kuti ndiani anoburitsa maringe neanongoita zviziviso. Mari yangu iri paSamsung pamwe neNissan.
ZVAUSATI KUITA:Usatenge "solid-mabhatiri ehurumende aripo izvozvi!" kubva kumawebhusaiti ane sketchy. Vari kunyepa. Kana chiri chaicho, chichange chiri munhau huru dzenhau uye kubva kuvagadziri vakuru.
Ehe uye chimwe chinhu: Kana uchida mabhatiri ZVINO uye uchida chimwe chinhu pakati pelithium yenguva dzose-ion uye-chiroto chakasimba? Tarisa mukatilithium polymer mabhatiri. Hadzina kusimba-asi dzakachengetedzeka kupfuura li-ion, hadzideredze, uye unogona kuzviwana nhasi. Inoshandiswa mumatani eRC zvinhu uye mamwe mafoni. Kwete revolutionary asi iripo lol.
