1 、 Lub zog siab electrolyte

Kev nrhiav lub zog tshwj xeeb yog qhov kev tshawb fawb loj tshaj plaws ntawm lithium-ion roj teeb, tshwj xeeb tshaj yog thaum cov khoom siv mobile tuav ntau thiab ntau qhov hnyav hauv tib neeg lub neej, qhov ntau, dhau los ua qhov tseem ceeb tshaj plaws ntawm cov roj teeb.

2 、 Lub zog siab hom electrolyte

Tam sim no, lub lag luam lithium-ion roj teeb yog qhov nyuaj rau kev ua tiav qhov siab ntawm kev tso tawm, qhov tseem ceeb yog vim li cas lub roj teeb ncej pob ntseg kub kub hnyav, kev ua haujlwm sab hauv coj mus rau tag nrho cov kub ntawm lub roj teeb siab dhau lawm, ua rau thermal runaway. . Yog li ntawd, rau electrolyte tuaj yeem cuam tshuam lub roj teeb los ntawm cua sov sai heev thaum tuav lub siab conductivity. Thiab hais txog lub hwj chim lithium roj teeb, kom ua tiav kev them nyiaj ceev kuj yog ib qho tseem ceeb ntawm kev txhim kho electrolyte.

3 、 Dav kub electrolyte

Lub roj teeb yog nquag mus rau decomposition ntawm electrolyte nws tus kheej thiab intensification ntawm sab cov tshuaj tiv thaiv ntawm cov khoom thiab electrolyte qhov chaw ntawm kub siab; thaum nyob rau ntawm qhov kub tsis tshua muaj tej zaum yuav muaj electrolyte ntsev los nag thiab ntau qhov tsis zoo SEI zaj duab xis impedance. Qhov hu ua dav kub electrolyte yog ua kom lub roj teeb muaj qhov chaw ua haujlwm dav.

4 、 Kev nyab xeeb electrolyte

Kev nyab xeeb ntawm lub roj teeb yog ib qho tseem ceeb hauv kev sib tsoo thiab txawm tias tawg. Ua ntej ntawm tag nrho cov, lub roj teeb nws tus kheej yog flammable, yog li thaum lub roj teeb yog overcharged, overdischarged los yog luv luv-circuited, thaum nws tau txais sab nraud pinprick los yog extrusion, thiab thaum lub sab nraud kub yog siab dhau heev lawm, tej zaum yuav ua rau muaj kev nyab xeeb xwm txheej. Yog li ntawd, nplaim taws retardant yog ib qho tseem ceeb kev taw qhia rau kev ruaj ntseg electrolyte kev tshawb fawb.

5 、 Lub voj voog ntev hom electrolyte

Txij li thaum tseem muaj teeb meem tseem ceeb hauv kev rov ua dua lithium-ion roj teeb, tshwj xeeb tshaj yog nyob rau hauv kev rov ua dua ntawm cov roj teeb lithium, kev txhim kho lub roj teeb lub neej yog ib txoj hauv kev los daws qhov teeb meem no. Muaj ob lub tswv yim tshawb fawb tseem ceeb rau lub voj voog ntev hom electrolyte, ib qho yog kev ruaj ntseg ntawm electrolyte, nrog rau thermal stability, tshuaj stability, voltage stability; Qhov thib ob yog kev ruaj ntseg nrog rau lwm cov ntaub ntawv, yuav tsum tau ruaj khov zaj duab xis tsim nrog electrodes, tsis muaj oxidation nrog diaphragm, thiab tsis muaj corrosion nrog collector kua.
