Lub roj teeb semi-solid state yog dab tsi?

Lub roj teeb semi-solid state yog dab tsi? Dab tsi yog qhov txawv ntawm lithium hlau phosphate roj teeb thiab ternary lithium-ion roj teeb?

Cov roj teeb yog qhov tseem ceeb rau peb lub neej niaj hnub, tab sis lawv tuaj ntau hom. Tshwj xeeb, ntau yam thev naus laus zis yog siv rau cov roj teeb uas muaj peev xwm siab, xws li cov roj teeb rau lub tsheb hluav taws xob thiab cov khoom siv hluav taws xob. Txawm li cas los xij, dab tsi yog tus yam ntxwv, qhov zoo, thiab qhov tsis zoo ntawm txhua hom roj teeb? Tsis tas li ntawd, nyob rau hauv qhov xwm txheej twg yog txhua hom roj teeb siv? Hauv tsab xov xwm no, peb yuav muab cov lus piav qhia meej thiab yooj yim to taub txog qhov sib txawv ntawm cov roj teeb hauv lub xeev ib nrab, cov roj teeb lithium hlau phosphate, thiab cov roj teeb lithium-ion ternary.

1. Lub roj teeb semi-lub xeev yog dab tsi?
Semisolid lub xeev roj teeb yog ib yam tshiab ntawm cov roj teeb uas sib txuas cov yam ntxwv ntawm cov khoom thiab cov kua electrolytes. Nws yog tsuas yog tsim rau cov roj teeb lithium-ion, uas muaj cov ion conductivity siab hauv cov electrolyte. Semisolid lub xeev roj teeb, raws li lub roj teeb thev naus laus zis nrog lub zog ceev, kev nyab xeeb, kev ua neej ntev, thiab kev cuam tshuam ib puag ncig qis, yog lub roj teeb zoo heev. Cov roj teeb hauv lub xeev muaj peev xwm muab faib ua peb hom: gel polymer hom, hom av nplaum thiab hom kua additive.

1) Gel polymer hom: hloov tau lub roj teeb nrog gel electrolyte. Nws muaj qhov zoo khoov tsis kam thiab kev them nyiaj ceev ceev. Haum rau daim npav thiab cov khoom siv hnav.
2) Hom av nplaum: Lub roj teeb zoo ib yam li av nplaum nrog electrolyte sib xyaw hauv cov electrode. Lub neej ua haujlwm ntev, tsis tshua muaj kev pheej hmoo ntawm cov kua xau thiab hluav taws kub. Haum rau kev tsim hluav taws xob hnub ci thiab kev siv tsheb.
3) Cov kua ua kua: Lub roj teeb ua los ntawm cov ceramic nrog me me ntawm electrolyte soaked hauv. Nws muaj cov thermal stability siab thiab tuaj yeem siv rau qhov kub thiab txias. Haum rau Is Taws Nem ntawm Yam, cov cuab yeej siv hauv tsev, thiab tsheb sab hauv.

Cov roj teeb raug them thiab tso tawm los ntawm kev txav ntawm ions ntawm qhov zoo thiab tsis zoo electrodes, thiab lawv cov npe txawv nyob ntawm seb hom ions. Piv txwv li, cov roj teeb lithium-ion muaj lithium hauv daim ntawv ionic. Txoj kev ntawm ion mus ncig yog hu ua electrolyte, thiab cov roj teeb lithium-ion siv cov kua electrolyte, tab sis cov kua no yog nplaim taws thiab txaus ntshai. Yog li ntawd, cov roj teeb uas siv cov khoom siv los yog gel electrolytes tau tsim. Cov no yog hu ua tag nrho cov roj teeb hauv lub xeev lossis cov roj teeb semi-solid state. Ua electrolyte rau hauv cov khoom lossis gel tuaj yeem txhim kho kev nyab xeeb ntawm roj teeb.

2. Dab tsi yog lithium hlau phosphate roj teeb?
Lithium hlau phosphate roj teeb yog lithium-ion roj teeb uas siv hlau phosphate (LiFePO4) ua cov electrode zoo. Hlau phosphate yog ib yam khoom pheej yig thiab ruaj khov uas tsis tshua muaj kev pheej hmoo ntawm thermal runaway lossis ignition. Lithium hlau phosphate roj teeb muaj lub neej ntev thiab ntau lub sijhawm them thiab tawm mus. Tsis tas li ntawd, vim hlau phosphate tsis yog hlau tsis tshua muaj, nws tuaj yeem hais tau tias nws qhov cuam tshuam rau ib puag ncig yog me me.

3. Dab tsi yog ternary lithium-ion roj teeb?
Lub roj teeb ternary lithium-ion yog ib hom roj teeb lithium-ion uas siv ternary compounds xws li npib tsib xee cobalt manganese (NCM) lossis npib tsib xee cobalt aluminium (NCA) ua cov electrode zoo. Lub tsev nyeem ternary muaj lub zog nrawm dua thiab cov zis ruaj khov txawm tias tsis kub. Txawm li cas los xij, nws qhov tsis zoo suav nrog tus nqi siab ntawm kev siv cov hlau tsis tshua muaj cobalt thiab muaj kev pheej hmoo siab ntawm thermal runaway thiab ignition.

Cov lus no qhia txog qhov zoo thiab qhov tsis zoo ntawm cov roj teeb hauv lub xeev ib nrab, lithium hlau phosphate roj teeb, thiab roj teeb lithium-ion ternary.
