Cov electrolytes ntawm lithium-ion roj teeb tuaj yeem muab faib ua ob hom: organic electrolytes thiab inorganic electrolytes, txhua tus muaj qhov sib txawv thiab qhov tsis zoo:
1, Organic electrolytes:
1. Qhov zoo:
High conductivity thiab ion conductivity: Organic electrolytes feem ntau muaj cov ion conductivity zoo, uas tuaj yeem pab txhawb kev them nqi thiab tawm cov txheej txheem ntawm cov roj teeb.
Siab solubility thiab viscosity tsawg: Organic electrolytes muaj siab solubility thiab viscosity tsawg, uas yog qhov zoo rau kev ua tiav cov ion hloov pauv siab hauv cov roj teeb.
Flexibility thiab plasticity: Organic electrolytes tuaj yeem tsim rau hauv cov qauv molecular sib txawv los tswj lawv lub cev thiab cov khoom siv hluav taws xob, yog li hloov mus rau cov qauv tsim roj teeb sib txawv.
Kev khiav hauj lwm kub qis: Organic electrolytes feem ntau ua haujlwm zoo ntawm qhov kub qis, uas yog qhov tseem ceeb rau kev siv xws li cov khoom siv nqa tau thiab lub tsheb fais fab hauv qhov chaw txias.
2. Qhov tsis zoo:
Tsis zoo thermal stability: Organic electrolytes yog nquag decomposition ntawm kub kub, uas yuav ua rau muaj kev ruaj ntseg teeb meem xws li overheating thiab luv circuits nyob rau hauv lub roj teeb, txwv tsis pub nws muaj peev xwm ua hauj lwm nyob rau hauv high kub.
Qhov teeb meem kev nyab xeeb: Organic electrolytes muaj cov thermal stability tsis zoo thiab yooj yim cuam tshuam los ntawm kev cuam tshuam sab hauv lossis kev puas tsuaj rau lub roj teeb, ua rau muaj kev nyab xeeb ntawm lub roj teeb.
2, Inorganic electrolytes:
1. Qhov zoo:
Zoo thermal stability: Inorganic electrolytes feem ntau muaj thermal stability thiab tuaj yeem ua haujlwm ntau dua qhov kub thiab txias yam tsis tau yooj yim decomposed, yog li txhim kho kev nyab xeeb ntawm cov roj teeb.
Chemical stability: Inorganic electrolytes muaj tshuaj lom neeg ruaj khov, tsis tshua muaj kev cuam tshuam rau kev puas tsuaj, thiab ua rau lub neej ntev ntawm cov roj teeb.
Tsawg conductivity: Vim tsis zoo ion conductivity, inorganic electrolytes tuaj yeem txo qhov tshwm sim ntawm tus kheej tawm hauv lub roj teeb, uas pab txhim kho lub sijhawm ntev cia ntawm lub roj teeb.
2. Qhov tsis zoo:
Tsawg ion conductivity: Cov ion conductivity ntawm inorganic electrolytes feem ntau qis dua li cov organic electrolytes, uas tuaj yeem txwv kev ua haujlwm ntawm cov roj teeb hauv kev siv hluav taws xob siab.
High viscosity: Qee cov inorganic electrolytes muaj viscosity siab, uas yuav ua rau kom lub zog sab hauv ntawm lub roj teeb thiab cuam tshuam rau kev them nqi thiab kev ua haujlwm ntawm lub roj teeb.
Hauv cov ntsiab lus, cov organic electrolytes thiab inorganic electrolytes txhua tus muaj lawv qhov zoo thiab qhov tsis zoo. Kev xaiv hom electrolyte uas tsim nyog nyob ntawm qhov yuav tsum tau ua ntawm lub roj teeb tsim, xws li kev nyab xeeb, lub zog ceev, lub voj voog lub neej, thiab kev ua haujlwm kub. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm technology, cov khoom siv electrolyte tshiab yuav tshwm sim los daws cov kev txwv tshwj xeeb ntawm cov roj teeb tam sim no.
