CovLiFePO4 roj teebpib nrog John B. Goodenough thiab Arumugam Manthiram.Lawv yog thawj tus pom cov khoom siv hauv cov roj teeb lithium-ion.Cov khoom siv anode tsis haum rau siv hauv cov roj teeb lithium-ion.Qhov no yog vim hais tias lawv nyob nraum nquag mus rau luv luv-circuiting tam sim ntawd.

Cov kws tshawb fawb pom tias cov khoom siv cathode yog lwm txoj hauv kev zoo dua raulithium-ion roj teeb.Thiab qhov no yog qhov tseeb heev hauv LiFePO4 roj teeb hloov pauv.Fast-forward los ntawm nce stability thiab conductivity thiab txhim kho txhua yam, thiab poof!LiFePO4 roj teeb tau yug los.

Niaj hnub no, muaj cov roj teeb LiFePO4 rechargeable nyob txhua qhov chaw.Cov roj teeb no muaj ntau yam siv tau zoo - lawv tau siv hauvnkoj,hnub ci tshuab,tshebthiab ntau dua.LiFePO4 roj teeb yog cobalt-dawb, thiab raug nqi tsawg dua li feem ntau ntawm nws cov kev xaiv (thaum sijhawm).Nws tsis muaj tshuaj lom thiab nws kav ntev dua.Tab sis peb yuav ua tiav qhov ntawd sai sai.Lub neej yav tom ntej muaj kev cia siab heev rau LiFePO4 roj teeb.
