Kushanda kweLithium-ion Power Batteries kwakadii?
Mwedzi wapfuura takava nemutengi akadzosa batch yemasero achiti "kuita kwakashata." Boka redu rekuedza parakaongorora, maseru aive akanaka-nyaya yaive yekuti system yavo yaibuda pa2C nguva dzose munzvimbo ine 40℃ambient, vakabva vaenzanisa zvawanikwa nenhamba dzedatabase dzakayerwa pa0.5C ne25 degrees . Kusawirirana uku kunoitika kakawanda pane kubvumwa neindasitiri, uye zvinonongedza nyaya yakakosha: lithium-ion battery performance haisi nhamba imwe chete. Inzvimbo yekupindura inoshanduka netembiricha, kurodha chimiro, mamiriro ekuchaja, uye zera.
Iyo CC{{0}CV yekuchaja protocol-inongogara iripo kusvika painogumira magetsi, yozoti volti isingachinjiki kusvika mazvino taper-ndiwo maitiro akajairika, asi chakakosha pakushandisa inogara{{3}chikamu chiripo. Ndiko kwaunowana kuwanda kwesimba rako kudzoka nekukurumidza. Takamhanyisa bvunzo dzekuenzanisa pamasero 242 Ah NCM pamitengo yakasiyana yekuchaja: kubva pa0.1C kuenda pa0.5C cheka nguva yeCC chikamu ne80%. The tradeoff is I²R kurasikirwa, iyo inoyera neazvino squared. Kune mutyairi wezvikepe anoda mota kudzoka munzira, kurova kwakanaka uku kunogamuchirwa. Kune grid yekuchengetedza system inokwenenzvera kutenderera{13}}kufamba zvakanaka kusvika kudesimali, hazvisi.
Kushanda kwe tembiricha ndiko kwatinopedzera maawa edu akawanda erutsigiro, kunyanya tiine makasitoma emamiriro ekunze ekuchamhembe nemisika yeSoutheast Asia-zvinetso zvakapesana, zvakafanana nefizikisi. Pa-20 madhigirii , maseru eLFP anodonha kusvika pamakumi matanhatu muzana anogona kushandiswa. NMC inobata zvirinani pakusvika 85%, ndosaka uchiiona mumaEV ekutanga akatengeswa kuti ashandiswe-mwaka wese. Maitiro acho anonzwisiswa zvakanaka: electrolyte viscosity inowedzera, SEI layer impedance inokwira, kufambisa kwechaji kunononoka pane yega interface. CATL's Shenxing Pro inoti 478 km kubva pamakumi maviri maminetsi e-20℃kuchaja (catl.com), inomiririra kufambira mberi kwechokwadi pamberi apa.
Kukwirisa-kushanda kunoita kuti misoro itemerwe nemusoro. Masero anoshanda zvakanaka{{2}dzimwe nguva zviri nani-pa35-40 madhigirii , asi kuchembera kwekarenda kunowedzera zvakanyanya. Tatsvaga mapepa munzvimbo dzinopisa-dzakarasikirwa ne8-10% yehuwandu mugore rekutanga maringe ne3-4% yemapakiti akafanana mumamiriro ekudzikama. Iyo yekushatisa makomisheni: SEI layer inokora, inoshandisa lithium inventory, inosimudza impedance, inoburitsa kupisa kwakawanda panguva yekuchovha bhasikoro, iyo inowedzera kuwedzera kuderera. Mutengi kuMiddle East akadzidza izvi nenzira yakaoma apo zvichemo zvavo zvegore rechipiri waranti zvakakwira.
Nhamba dzehupenyu hwepamhepo pamapepa ezvinyorwa zvinotora mamiriro chaiwo{{0}kazhinji 25 madhigirii , 1C/1C kuchaja-kuburitsa, 100% kudzika kwekubuda. Shandura chero shanduko uye nhamba dzinochinja zvakanyanya. Isu tinoudza vatengi kuti 50% mashandiro eDOD anowanzo kuwedzera hupenyu hwekutenderera ne3-5x zvichienzaniswa nekudzika kwakazara bhasikoro. Musiyano uripo pakati pe500-1,000 cycles pa100% DOD uye 3,000-5,000 cycles pa50% DOD ine mhedzisiro yakakura pamutengo wakakwana wevaridzi, asi zvinoda kuwandisa paki, izvo zvinowedzera mutengo wepamberi nehuremu. Injiniya ndeye tradeoffs; kusarudzwa kwebhatiri hakunawo.
Kuita kwekuchengetedza kunosvika pakudzikama kwekupisa, uye kugadzikana kwekupisa kunouya kumakemikari. LFP's olivine structure inobata maatomu eokisijeni zvakasimba{{1}kuwora kwemafuta hakutangire kusvika 270℃, zvichienzaniswa ne210℃yeNMC. Ndosaka maseru eLFP achipfuura bvunzo dzekupinza zvipikiri izvo zvinotumira masero enickel akakwira-maseru e nickel mukupisa. Icrystallography, kwete kushambadzira. China itsva GB38031-2025 yakajairwa, inoshanda muna Chikunguru 2026, inoda maawa maviri ekushaya moto uye pasina kuputika mushure mekutangisa kwekupisa kwekupisa. Zvinoenderana neongororo yeindasitiri, vangangoita 78% yevagadziri vatove nehunyanzvi hwekutevedzera (greencarcongress.com). Vasara 22% vane basa reinjiniya pamberi pavo.
Kugadzira zvemhando yepamusoro kunonyanya kukosha kupfuura zvinofungwa nevatengi vakawanda-kupfeka kufanana, kuomesa kuzara, kudzivirira kusvibiswa. Battery University inocherekedza kuti "hapana nzira inoshanda iripo yekuyera ese mamiriro ebhatiri munguva pfupi, yakazara bvunzo," ndosaka mutengesi achitevera rekodhi zvine chekuita nezvakatsanangurwa.
Solid-state, silicon anodes, sodium-ion-tekinoroji iyi iri kufambira mberi kubva murabhu kuenda pakugadzira muyero. Amprius yakaratidza 500 Wh/kg ine silicon anodes. CATL's sodium-ion Naxtra inowana 175 Wh/kg ne10,000-hupenyu hwekutenderera. Ingave izvi zvichichinja musika mumakore matatu kana mashanu, -chizvarwa chelithium-ion chazvino chicharamba chiri chinotyisa pamashandisirwo mazhinji mumakore gumi ano. Iyo envelopu yekuita inoramba ichikura, asi izvo zvakakosha zvekufananidza maseru maitiro kune zvinodiwa zvekushandisa hazvina kuchinja.
