Core Functions ntawm Mica hauv EVs
1. Roj teeb rwb thaiv tsev
Hauv tsheb fais fab, roj teeb kev nyab xeeb nyob ntawm siab -kev ua haujlwm rwb thaiv tsev.Mica ua ob qho tib sitxheej caisthiab adielectric barriernyob rau hauv lithium{0}} roj teeb ion, stabilizing ib leeg hlwb, txo thermal runaway txaus ntshai, thiab thaiv cov cua kub hloov ntawm cov hlwb.
Mica's non-combustible nature and low thermal conductivity ua rau nws zoo tagnrho rau kev nyab xeeb-cov roj teeb tseem ceeb ib puag ncig.Nws tuaj yeem tsim tau raws li:
Nyias, hloov tau mica nplooj ntawvrau complex- roj teeb zoo li tus
Rigid mica daim hlaurau siab - thaj chaw tiv thaiv
Qhov yooj yim no tso cai rau mica rwb thaiv tsev kom haum ze li ntawm EV roj teeb tsim.
Tswv yim: Mica rwb thaiv tsev nyob rau hauv lub roj teeb tshuab thaiv ob qho tib si hloov hluav taws xob thiab hluav taws xob hla- tham ntawm hlwb, tiv thaiv luv luv Circuit Court.
2. EV Kev Nyab Xeeb
Kev nyab xeeb yog qhov tseem ceeb hauv cov tsheb hluav taws xob.Mica tiv thaiv cov roj teeb thiab cov khoom siv hluav taws xob los ntawm cov cua sov thiab hluav taws xob surges, ua raws li hluav taws kub thiab thermal barrier txawm tias thaum lub sij hawm thermal runaway txheej xwm.
Mica-cov ntaub ntawv rwb thaiv tsev raws li covUL 94 V-0 flammability tus qauv, txhais tau hais tias lawv yog cov nplaim taws heev- tiv taus txawm tias qhov kub thiab txias.
Cov roj teeb pob
High -voltage Cheebtsam
Kev them nyiaj system
Nws ua kom ruaj khov ua haujlwm txawm tias nyob rau hauv cov xwm txheej hnyav.
3. Thermal stability
Cov roj teeb yuav tsum tau rwb thaiv tsev uas tiv taus cua sov heev.Mica tswj kev ua haujlwm tshwj xeeb ntawm qhov kub thiab txias:

|---|---|
| Muscovite | 600 degree |
| Phlogopite | 1000 degree |
Qhov kev ruaj ntseg no tiv thaiv cov roj teeb thaum lub sij hawm siab - lub hwj chim tawm los yog kub sab nraud, txo qhov hluav taws kub.
4. High Dielectric zog
Mica ua haujlwm zoo thaiv tam sim no los ntawm ntws qhov twg nws yuav tsum tsis txhob, tiv thaiv luv luv circuits.
| Khoom siv | Dielectric zog (kV / mm) | Dielectric tsis tu ncua | Kev nqus dej |
|---|---|---|---|
| Muscovite | 2000 – 78.74 | 6–7 | Tsawg heev |
| Phlogopite | 1500 – 59.05 | 5–6 | Tsawg heev |
Nws lub zog dielectric siab ua kom muaj kev nyab xeeb, ruaj khov roj teeb ua haujlwm.
5. Tshuaj Inertness
Mica tsis hnov mob nrog dej, oxygen, acids, lossis cov khoom siv tshuaj lom neeg.
6. Tsim Flexibility
Mica tuaj yeem tsim ua cov yeeb yaj kiab nyias, cov nplooj ntawv hloov tau yooj yim, lossis cov phaj nruj.
