Tesla adzagwiritsa ntchito maselo a LiFePO4 m'malo mwa ma cell a cobalt ku China?
Nkhani zosangalatsa zochokera ku Far East. Reuters Imati Tesla Ali Pakukambitsirana Koyambirira ndi Wopereka Battery LiFePO4 (Lithium Iron Phosphate, LFP). Amapereka mphamvu yocheperako kuposa ma cell ena a lithiamu-ion a cobalt, komanso ndi otsika mtengo kwambiri.
Kodi Tesla adzatsimikizira dziko kuti ligwiritse ntchito ma cell a LFP?
LFP (LiFePO4) samalowa m'magalimoto kawirikawiri chifukwa amatha kusunga mphamvu zochepa pa kulemera komweko. Izi zikutanthauza kuti kuyesa kusunga mphamvu ya batire yosankhidwa (monga 100 kWh) kumafuna kugwiritsa ntchito mapaketi akuluakulu ndi olemera kwambiri. Ndipo izi zitha kukhala vuto galimoto ikadumpha matani 2 kulemera kwake ndikuyandikira matani 2,5 ...

Komabe, malinga ndi Reuters, Tesla akukambirana ndi CATL kuti apereke maselo a LiFePO.4... Ziyenera kukhala zotsika mtengo "ndi makumi angapo peresenti" kuposa "zenizeni". Sizinawululidwe ngati maselo a NCA omwe Tesla amagwiritsa ntchito padziko lonse lapansi amaonedwa kuti ndi "omwe alipo," kapena kusiyana kwa NCM komwe akufuna (ndipo akugwiritsa ntchito?) Ku China.
NCA ndi maselo a nickel-cobalt-aluminium cathode ndipo NCM ndi maselo a cathode a nickel-cobalt-manganese.
Maselo a LiFePO4 ali ndi zovuta izi, koma alinso ndi zabwino zingapo: mayendedwe awo otulutsa amakhala opingasa kwambiri (kutsika kwamagetsi pang'ono panthawi ya opareshoni), amalimbana ndi zowongolera zotulutsa ndipo amakhala otetezeka kuposa maselo ena a lithiamu-ion. Zimakhalanso zovuta kuwerengera kuti sagwiritsa ntchito cobalt, yomwe ndi chinthu chamtengo wapatali ndipo nthawi zonse imayambitsa mikangano chifukwa cha malo omwe ali nawo komanso ana omwe amazolowera kugwira ntchito m'migodi.
