Chii Chiri Nani, Lithium-Ion kana Lithium Iron Phosphate Mabhatiri?
Zvekuchengetedza zvakamira uye zvekufambisa zvekutengesa, LFP inohwina pamutengo wakakwana wevaridzi munenge makumi masere muzana emapurojekiti atinoona. NMC ichiri kuita zvine musoro pahuremu-zvisina kumanikidzika uye kutonhora{3}}kutumirwa kwemamiriro ekunze pasina bhajeti rekutonga kwemafuta. Ndiyo mhinduro pfupi.
Mhinduro refu inosanganisira yako chaiyo yebasa kutenderera, yako saiti zvipingaidzo, uye nekutendeka, izvo CFO yako inoda kusaina kuti ienderere mberi nemitengo yehupenyu. Kana uri kuenzanisa makotesheni evatengesi izvozvi kana kuvaka imwe yeRFP, zvimwe zvese izvi zvinobata izvo zvatakadzidza mukuita.
Kutorwa kwemusika weLFP kwakaitika nekukurumidza kupfuura zvakafanotaurwa nevanoongorora. 49% yepasi rose EV mabhatiri ekushandiswa muna 2024, pedyo-nesimba rose mukuchengetwa kwegridi. Tesla akachinja Megapack kuCATL's LFP maseru uye akawedzera waranti kusvika kumakore gumi nemashanu. BYD's 12.5 GWh chirongwa neSaudi Electricity Company chakaenda kuLFP. CATL inotaura zero yezviitiko zvekupisa mukati me256 GWh yakaiswa. Iyo indasitiri yakavhota nesarudzo dzayo dzekutenga.
Asi zvinyorwa zvekuenzanisa chemistry zvinotenderera zvinopotsa izvo zvinofambisa sarudzo idzi padanho reprojekiti. Nhamba dzesimba remagetsi hadzikuudze kana kuisirwa kwako kuchizokwana mune yakagoverwa tsoka. Cycle life specs haiverengeri maitiro ekudzikisira aunozoona pasi pemamiriro ako ekushanda. Yakabudiswa thermal runaway set tembiricha haishandure zvakananga kune izvo zvichadiwa nefire marshal.
Chaiyo-World Case Study
Takanga tine telecom mutengi gore rapfuura spec NMC yekuisa backup nekuti nhamba dzesimba remupi dzaitaridzika zviri nani pabepa. Kushanya kwesaiti kwakaratidza kuti vaizoda kuwedzera HVAC kugona kubata iyo inopisa. Kukwidziridzwa kwekudzimisa moto kwakasundidzira nguva kumashure mwedzi mitatu. Mari yese yakaiswa yakauya mu22% pamusoro peiyo LFP imwe nzira yavaimboramba. Masero eNMC pachawo aive akachipa pakWh. Zvose zvakavapoteredza zvakanga zvisipo.
Uyu muenzaniso unodzokorora. Iyo bhatiri chemistry sarudzo inowira mumitengo yeBOS, inobvumidza nguva, zvinodiwa inishuwarenzi, uye zvibvumirano zvekugadzirisa. Mapoka ekutenga akatarisana nepadiki-level specs kupotsa masisitimu aya-level effects.
Pahupenyu hwekutenderera, nhamba dzevatengesi dzinofanirwa kuongororwa. "5,000 kutenderera kusvika ku80% huwandu" inonzwika yakatwasuka kudzamara wachera mumamiriro ebvunzo. Ndeipi C-mwero? Zvakadzika sei zvekubuda? Ndeipi tembiricha yemhando? Sero rakaedzwa pa 0.5C uye 25 dhigirii murabhoritari inoita zvakasiyana zvakanyanya kubva kune rimwe bhasikoro pa1C mumudziyo wekutakura muPhoenix.
Mashoko chaiwo-epasi rose ezvikepe ari kutanga kubuda. Electric School Bus Initiative yatsvaga 847 LFP-mabhazi ane midziyo uye yakaratidza kuderedzwa kwe7.2% mumakore mashanu ekushanda chaiko. Izvo zviri nani pane fungidziro zhinji dzewaranti. Zvikepe zveNMC zvinoratidza kusiyana kwakawanda-zvimwe zvakamira zvakanaka, zvimwe zvichirova zvikumbaridzo zvewaranti kare kupfuura zvaitarisirwa. Hunhu hwesero uye kudziya kwehutongi hwemhando inobata zvakanyanya kupfuura chemistry label pane spec sheet.
Iyo DOE's 2020 gidhi rekuchengetedza ongororo yakaratidza LFP inogara ingangoita 67% kureba kupfuura NMC pasi pemamiriro akafanana eku bhasikoro. Rakabudiswa pa energy.gov. Mamiriro acho aifarira maprotocol ebvunzo, saka-musiyano chaiwo wepasi rose uchasiyana, asi mhedziso yegwara inobata pane akawanda mashandisirwo atakaita.
Kutonhora kwemamiriro ekunze ndiko uko LFP inodonha zvechokwadi, uye haisi yekungodzikiswa kwesimba.
Kuchaja LFP pazasi 0℃kunokonzera lithium plating pane anode. Hazvina kuderedzwa kuita-kukuvadzwa kwechigarire kunoungana nechiitiko chega chega chinotonhora. Sero rinotaridzika zvakanaka. BMS inogona kusaratidza chero chinhu. Asi iwe uri kudzikisira paki nguva dzese.
Indasitiri yekuchaja mapuroteni anopindura nekupwanya machaji mareti pakudziya kwakaderera. Pa-10 madhigirii , mwero unotenderwa unodzika kusvika pa 0.02C. Maawa makumi mashanu nekuwedzera kuti muchaji izere pamwero iwoyo. Zvinobudirira zvisingagoneki pasina kupisa kunoshanda.
Takataura mapurojekiti ari kumusoro kuMidwest uko kunodzora kupisa kwakawedzera 12-18% kumutengo wesystem. Insulated enclosures, kudziyisa zvinhu, zvinodzora. Zvichiri kunyorwa penzura zvichipesana neNMC paTCO yemakore gumi, asi Year 1 capital hit yaive chaiyo uye yaida kusaina-yepamusoro kupfuura bhajeti repurojekiti yekutanga.
Kana kuisa kwako kwakatarisana netembiricha -yakadzikama uye bhajeti yako yekudziisa ikaganhurirwa, NMC inogona kunge iri runhare chairwo zvisinei nemutengo wepamusoro wehupenyu. Takataura nevatengi muNMC nechikonzero ichi chaizvo. Haasi ese mapurojekiti anofanira kunge ari LFP.
Pamitengo, ongororo yeBloombergNEF 2024-2025 inoratidza mutengo wepack-level inoita madhora makumi masere nerimwe/kWh yeLFP maringe ne$128/kWh yeNMC. Asi mitengo yepakiti haitore izvo zvauchabhadhara chaizvo.
Mitengo yemasero eChinese LFP yakadzikira pasi pe$50/kWh kusvika pakati-2024. Zvimwe zvekutengesa zvinonzi zvakavharwa pasi pemadhora makumi mana/kWh. Mamiriro ekuwedzera ndeyechokwadi-CATL uye BYD yakakwikwidziridzwa pamberi pekuda, uye vadiki vagadziri vari kuvharisa zvinhu. Kana iwe uchitenga vhoriyamu uye timu yako yekutenga ichiziva kutaurirana, mavhareji akadhindwa masirin'i, kwete pasi.
The flip side: masero akachipa kubva kune vanonetsekana vatengesi dzimwe nguva zvinoreva kusiyana kwemhando. Takaona mabhechi ane huwandu hwakapararira kupfuura spec. BMS calibration nyaya. Zvinyorwa zvisingaenderani nezviri mukireti. Masero e$45/kWh anoda 15% yakawanda yevashandi veQC uye anogadzira zvichemo zvewaranti haachengete mari.
Hukama hwakavamba netier-mutengesi mumwe chete (CATL, BYD, EVE, CALB yeLFP; Samsung SDI, LG Energy Solution, SK On yeNMC) vanotengeserana imwe mari yemubhadharo kuti ivimbike. Kushivirira kwako kwenjodzi uye vhoriyamu yekutenga inotarisisa pekumhara pane iyo spectrum.
Lifecycle mutengo kuverenga kunoda fungidziro nezve mashandisirwo anosiyana nekushandisa.
