Tesla achashandisa LiFePO4 masero muChina panzvimbo yecobalt-based cell?
Nhau dzinonakidza kubva kuFar East. Reuters Inoti Tesla Ari Mukutaura Kwekutanga NeBattery Provider LiFePO4 (Lithium Iron Phosphate, LFP). Ivo vanopa yakaderera simba density pane mamwe cobalt-based lithium-ion masero, asi zvakare akachipa zvakanyanya.
Ko Tesla achaita kuti nyika ishandise masero eLFP?
Iyo LFP (LiFePO4) kashoma kupinda mumotokari nekuti vanogona kuchengeta simba shoma rehuremu hwakafanana. Izvi zvinoreva kuti kuedza kuchengetedza bhatiri rakasarudzwa (semuenzaniso 100 kWh) kunoda kushandiswa kwemabhatiri akakura uye anorema. Uye iro rinogona kuve dambudziko kana mota yasvetuka matani maviri muhuremu uye yava kusvika 2 matani ...

Nekudaro, maererano neReuters, Tesla ari muhurukuro neCATL kuti ape LiFePO maseru.4... Dzinofanirwa kunge dzakachipa "nemakumi akati wandei kubva muzana" pane "chaiwo". Hazvina kubudiswa pachena kana masero eNCA anoshandiswa naTesla pasi rose aionekwa se "aripo," kana NCM yakasiyana yainoda (uye iri kushandisa?) MuChina.
NCA ndeye nickel-cobalt-aluminium cathode masero uye NCM ndeye nickel-cobalt-manganese cathode masero.
LiFePO masero4 vane zvipingamupinyi izvi, asi vanewo zvikomborero zvakati wandei: curve yavo yekuburitsa yakanyanya kuchinjika (minimal voltage kudonha panguva yekushanda), ivo vanotsungirira machaji-discharge cycles uye vakachengeteka kupfuura mamwe masero e-lithium-ion. Izvo zvakaomawo kuwedzeredza chokwadi chekuti havashandisi cobalt, iyo inodhura chinhu uye inogara ichikonzera kukakavara nekuda kwenzvimbo yemadhipoziti ayo uye vana vakajaira kushanda mumigodhi.
