Muva nje, abacwaningi baseStanford University, eU.SA baye badala isihlukanisi esisha esihlakaniphile sokuphotha i-electrostatic, esinomshini wokushisa ukushisa, oqukethe ama-flame retardants, angasetshenziswa ekushiseni kwebhethri ye-lithium ion. Kulokhu kulungiselelwa, i-flame retardant ihlanganiswa ngaphakathi kwegobolondo le-polymer yesondlo, futhi ipeni elivimbela ilangabi lincibilika ngokuqondile ku-electrolyte, bese umsebenzi webhethri uthinteka kabi. Lapho ukushisa ngaphakathi kwephakethe lebhethri le-lithium ion kuphezulu kakhulu, igobolondo lokugcinwa kwebhethri lizoncibilika ngenxa yamazinga okushisa aphezulu, likhulule i-retardant yomlilo, bese lisebenzisa ukuvutha kwe-electrolyte okuvutha kakhulu.

1. Faka ishaja yoqobo: isikhathi sokushaja isikhathi esiphezulu sesigameko sokuqhuma kwephakethe lebhethri le-lithium ion. Ishaja yangempela inamandla kakhulu kuneshaja ehambisanayo ukuze kuqinisekiswe ukuphepha kwebhethri.

2. Faka ibhethri eliqinile: zama ukuthenga ibhethri langempela noma ibhethri lomkhiqizo odumile, njengebhethri le-lithium-ion le-Haobo Battery, ungathengi izinto ezisetshenziswayo noma izinto ezihambisanayo ukuze wonge imali, amabhethri anjalo angase alungiswe, hhayi njengebhethri langempela. 3.

Ungabeki iphekhi yebhethri endaweni yezigxobo: izinga lokushisa eliphezulu, ama-bumps, njll. ziyimbangela ebalulekile yokuqhuma kwephakethe lebhethri ye-lithium ion, zama ukwenza ibhethri endaweni ezinzile, kude nendawo yendawo. 4.

Ungakuhloli ukuguqulwa: Ngemva kokulungiswa, ibhethri lingase libe nendawo ebingakaze icatshangelwe ngaphambilini, yengeze izingozi zokuphepha. Ukusabela kweketango lama-hydroxide radicals ngesikhathi sokusabela kwebhethri ye-lithium-ion kuyaqhubeka nokukhipha ukushisa okukhulu, okuwumthombo oqinile obangela ukuthi ibhethri ishise noma liqhume, khona-ke ibhethri le-anti-ion lisezingeni lomlilo noma ukuqhuma, njengoba kuboniswe ngezansi. 1.

Ukuvikelwa ngamasekhethi okuvikela angaphandle azinikele, njengalokhu: ukushaja ngokweqile ngebhethri ye-lithium ion, faka iswishi ye-polymer ye-PTC noma ivalvu yokuphepha evimbela ukuqhuma kukepisi yokuphepha yebhethri. 2, ukuzinza okushisayo kwebhethri ye-lithium ion kuhlobene nohlobo lwezinto ezinhle, i-electrolyte. Ngokuthuthukisa izimo zokwenziwa, izindlela zokwenziwa ezithuthukisiwe, ezokwenziwa, zokwenziwa, izinto zokwakha ezinhle; noma sebenzisa ubuchwepheshe obuyinhlanganisela obufana namasu okusebenzisa i-doping, amasu okuvala indawo (njengamasu okumboza) ukuze kuthuthukiswe ukuzinza kokushisayo kwempahla ye-electrode ekhangayo.

3. I-oxidation ebuthakathaka yengaphezulu lezinto zekhabhoni, njengokuthi: ukunciphisa, i-doping, ukuguqulwa kwendawo, njll., noma ukusebenzisa i-spherical, i-fibrous carbon negative electrode material ukuze kuthuthukiswe ukuzinza kokushisayo kwebhethri.

4, kusetshenziswa usawoti we-lithium ozinze kahle, ukuzinza okungaba khona kanye ne-solvent ebanzi ukuze kuthuthukiswe ukuzinza okushisayo kwebhethri. Ngaphezu kwalokho, inani elithile le-flame retardant (i-organic phosphorus retardant, i-silane, i-borate, njll.) yengezwa ku-electrolyte ephilayo futhi kuyindlela eqinile yokuthuthukisa ukuphepha kwebhethri.
