Lub electrolyte yog ib qho tseem ceeb ntawm cov nyiaj lifepo4 roj teeb, uas muaj qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm, kev nyab xeeb thiab kev nyab xeeb ntawm lub roj teeb.
Lub electrolyte muaj cov haujlwm ntawm ion kev kho, tshuaj lom neeg ruaj khov thiab kev sib txuam nrog cov txheej txheem hluav taws xob (liface Cov kev ua haujlwm hluav taws xob ntau ntawm cov roj teeb (kwv yees li 2. {}}
Cov roj teeb lifo₄ feem ntau siv cov organic kua electrolyte, uas yog feem ntau muaj ntawm peb ntu no:
1. Lithium ntsev: Nws yog tus nqa khoom uas muab lithium ions (li⁺). Feem ntau siv cov ntsev Lithium yog: lithium hexafuorophphate (Lithb₄
2. Organic kuab tshuaj: Nws lub luag haujlwm yog kom yaj lithium ntsev thiab ua raws li nruab nrab rau ion thauj. Feem ntau siv cov kuab tshuaj: carbonate sib xyaw cov kuab tshuaj,
Xws li:
Cyclic carbonates: Ethylene Carbonate (EC), Propylene Carbonate (PC) (PC) (AIDS High Deithium ntsev rov qab). Carbonates cov carbonates: DMC), dithyl carbonate (decc carbonate (EMC) (qis viscosity, tsis muaj viscosity, tsis muaj kev txhim kho flush).
Kev sib xyaw sib xyaw: Feem ntau ECC lossis EC ECC kom sib npaug ntawm qhov tso cai thiab viscosity.
3. Ntxiv (me me): Txhim kho cov khoom tshwj xeeb.
Zaj duab xis ua yeeb yam ntxiv, xws li Vinylene Carbonate (VC), ua tiav SEI zaj duab xis (khoom electrolyte interface) nyob rau saum npoo ntawm anode.
Anti-overcharge ntxiv ntxiv: xws li biphenyl (bp), uas txwv tsis pub muaj electrolyte thaum lub roj teeb tau dhau.
Nplaim taws retardant additives, xws li phosphate esters, rau ntxiv kev nyab xeeb.
Qhov hluav taws xob ntawm lub roj teeb hluav taws xob yog ib lub cev ua kua nrog lithold₆ li Lithium ntsev thiab cov pa roj tov sib xyaw ua ke. Nws yuav tsum tau tsim los ntawm Ionic conductivity, tshuaj lom neeg ruaj khov, thiab interfacial compatibility nyob rau hauv lub siab. Nyob rau hauv lub neej yav tom ntej, khoom electrolytes thiab kev tsim kev nyab xeeb yuav yog cov lus qhia kev txhim kho loj.
AceY muaj tswv yimyog tus kws tshaj lij kev tsim tshwj xeeb hauv Lithium roj teeb siv tshuab, cov roj teeb ntim rau cov khoom siv hluav taws xob me me.Yog xav hu rau peb.
