Guoxuan: Tafika pa 0,212 kWh / kg m'maselo athu a LFP, timapita patsogolo. Awa ndi masamba a NCA / NCM!
A Guoxuan Chinese adadzitamandira kuti adalowa m'dera lomwe kale linali ndi ma cell a lithiamu-ion okhala ndi ma cathodes okhala ndi cobalt. Kampaniyo idati idakwanitsa kupeza mphamvu yopitilira 0,2 kWh / kg mu cell yatsopano ya lithiamu iron phosphate (LFP).
Maselo a LFP - tsiku lina "ofooka kwambiri" amakhala "abwino mokwanira"
Maselo a Lithium iron phosphate ali ndi zabwino zambiri: sagwiritsa ntchito cobalt, motero zotsika mtengo kuposa ma cell okhala ndi ma cathodes okhala ndi chinthu ichi. Komanso, iwo zosapsa ikawonongeka ndi kupirira zikwizikwi za kulipiritsa... Amakhalanso ndi vuto limodzi lalikulu: amapereka mphamvu zochepa kuposa maselo a NCA / NCM chifukwa ali pansi pa 0,2 kWh / kg, pamene NCA / NCM yadutsa 0,25 ndipo ikuyandikira 0,3 kWh. / kg.
Zakhala choncho mpaka pano.
Kampani yaku China Guoxuan, yomwe pakadali pano imapereka ma cell a LFP kumsika waku China, akuti yakwanitsa kupanga ma cell a lithiamu iron phosphate mu sachets (chithunzi) chokhala ndi mphamvu ya 0,212 kWh / kg. Sizinathebe, kampaniyo ikufuna kufika 2021 kWh / kg mu 0,23 mpaka 2022 kWh mu 0,26, yomwe ili kale mtengo pafupi ndi ma cell a NCA / NCM.
Wopanga amadzitamanso kuti amagwiritsa ntchito ukadaulo wa jelly-roll-to-module, womwe, monga dzina limanenera, umalola. pogwiritsa ntchito magulu a maselo ngati ma modules, popanda mipanda yowonjezera. Komabe, chithunzichi sichikusonyeza kuti chiyanjano chimapereka mwayi wotero. Ngati ndi choncho, ndiye kuti iyenera kukhala ndi "chisa" chamtundu wina, chimango chachitsulo chomwe chimamangiriridwa pamphepete mwa sachet, osachepera timaganiza choncho.
