Tsis ntev los no, cov kws tshawb fawb ntawm Stanford University, Tebchaws Asmeskas tau tsim lub tshuab ntse electrostatic spinning separator tshiab, uas muaj lub tshuab ua kom sov, uas muaj cov nplaim hluav taws xob, uas tuaj yeem siv rau kev ceeb toom lithium ion roj teeb combustion. Hauv qhov kev teeb tsa no, cov nplaim hluav taws kub hnyiab tau ntim rau hauv lub plhaub polymer tu, thiab cov cwj mem los tiv thaiv nplaim hluav taws ncaj qha rau hauv cov electrolyte, thiab tom qab ntawd cov roj teeb ua haujlwm tsis zoo. Thaum tshav kub hauv lub lithium ion roj teeb pob yog siab dhau lawm, lub roj teeb tu lub plhaub yuav yaj vim qhov kub thiab txias, tso cov nplaim hluav taws, thiab tom qab ntawd siv cov hluav taws xob hluav taws xob hluav taws xob siab.

1. Siv tus thawj charger: lub sij hawm them nqi yog lub sij hawm siab ntawm qhov tshwm sim tawg ntawm lithium ion roj teeb pob. Thawj lub charger muaj zog dua li cov charger sib xws kom muaj kev nyab xeeb ntawm roj teeb.

2. Siv lub roj teeb ruaj khov: sim yuav cov roj teeb qub lossis cov roj teeb uas muaj npe nrov, xws li lithium-ion roj teeb ntawm Haobo Battery, tsis txhob yuav cov khoom siv thib ob lossis sib npaug kom txuag nyiaj, cov roj teeb zoo li no yuav raug kho, tsis zoo li lub roj teeb qub. 3.

Tsis txhob tso lub roj teeb rau hauv ib puag ncig ntawm ncej: kub, pob, thiab lwm yam. yog qhov tseem ceeb ntawm qhov tawg ntawm lithium ion roj teeb pob, sim ua kom lub roj teeb nyob rau hauv ib qho chaw ruaj khov, nyob deb ntawm lub zos hauv zos. 4.

Tsis txhob kuaj qhov kev hloov kho: Tom qab kev hloov kho, lub roj teeb yuav muaj ib puag ncig uas tsis tau txiav txim siab ua ntej, ntxiv kev nyab xeeb. Cov saw hlau cov tshuaj tiv thaiv ntawm cov hydroxide radicals thaum lub sij hawm cov tshuaj tiv thaiv ntawm lithium-ion roj teeb tseem tso tawm ntau cov cua sov, uas yog qhov nruj uas ua rau lub roj teeb kub hnyiab los yog tawg, ces cov roj teeb los tiv thaiv ion yog nyob rau hauv qhov ntsuas hluav taws kub los yog tawg, raws li qhia hauv qab no. 1.

Kev tiv thaiv los ntawm kev tiv thaiv kev tiv thaiv sab nraud, xws li: overcharge nrog lithium ion roj teeb, nruab ib lub PTC polymer hloov lossis tawg-pov thawj kev nyab xeeb valve hauv lub hau kev nyab xeeb ntawm lub roj teeb. 2, thermal stability ntawm lithium ion roj teeb muaj feem xyuam rau cov khoom zoo, cov electrolyte. Los ntawm optimizing cov khoom siv hluavtaws, txhim kho cov txheej txheem hluavtaws, cov khoom siv hluavtaws, cov khoom siv hluavtaws, cov khoom siv hluavtaws zoo; los yog siv cov thev naus laus zis xws li cov txheej txheem doping, cov txheej txheem cladding nto (xws li txheej txheej txheej) los txhim kho cov thermal stability ntawm cov khoom zoo electrode.

3. Tsis muaj zog oxidation ntawm qhov chaw ntawm cov khoom siv carbon, xws li: txo qis, doping, kev hloov kho deg, thiab lwm yam, los yog siv cov khoom siv spherical, fiber ntau carbon tsis zoo electrode los txhim kho thermal stability ntawm lub roj teeb.

4, siv lub lithium ntsev zoo ruaj khov, muaj peev xwm ruaj khov thiab dav hnyav los txhim kho thermal stability ntawm lub roj teeb. Tsis tas li ntawd, qee qhov hluav taws kub retardant (organic phosphorus nplaim taws retardant, silane, borate, thiab lwm yam) ntxiv rau cov organic electrolyte kuj yog ib txoj hauv kev nruj kom txhim kho roj teeb kev nyab xeeb.
