Isingeniso:
Amabhethri e-lithiumsezibe yingxenye ebalulekile yempilo yethu yansuku zonke, zinika amandla yonke into kusukela kuma-smartphone nama-laptop kuya ezimotweni zikagesi kanye nezinhlelo zokugcina amandla. Amabhethri e-lithium asetshenziswa kabanzi, kodwa kube nezigameko zomlilo nokuqhuma, okuye kwaphakamisa ukukhathazeka ngokuphepha kwawo, nakuba kungavamile. Ukuqonda izici ezingaholela ezigamekweni ezinjalo kubalulekile ekuqinisekiseni ukusetshenziswa okuphephile nokuthembekile kwamabhethri e-lithium.
Ukuqhuma kwebhethri le-lithium kuyinkinga enkulu yokuphepha, futhi izimbangela zokwenzeka kwazo ziyinkimbinkimbi futhi ziyahlukahluka, ikakhulukazi kufaka phakathi izici zangaphakathi nezangaphandle.
Izici zangaphakathi
Isekhethi esifushane sangaphakathi
Umthamo we-electrode engalungile owanele: Uma umthamo we-electrode engalungile we-electrode elungile yebhethri le-lithium unganele, ama-athomu e-lithium akhiqizwa ngesikhathi sokushaja awakwazi ukufakwa esakhiweni se-interlayer ye-graphite engalungile, futhi azowela phezu kobuso be-electrode engalungile ukuze akhe amakristalu. Ukuqongelela isikhathi eside kwala makristalu kungabangela i-short circuit, iseli lebhethri liphuma ngokushesha, likhiqize ukushisa okuningi, lishise i-diaphragm, bese kubanga ukuqhuma.
Ukumuncwa kwamanzi nge-electrode kanye nokusabela kwe-electrolyte: Ngemva kokuba i-electrode imuncwe amanzi, ingase isabele ne-electrolyte ukuze ikhiqize amaqhubu omoya, okungase kubangele ama-internal short circuits.
Izinkinga ze-Electrolyte: Ikhwalithi kanye nokusebenza kwe-electrolyte ngokwayo, kanye nenani loketshezi olufakwa ngesikhathi sokujova olungahlangabezani nezidingo zenqubo, kungathinta ukuphepha kwebhethri.
Ukungcola enkambisweni yokukhiqiza: Ukungcola, uthuli, njll. okungaba khona ngesikhathi senqubo yokukhiqiza ibhethri nakho kungabangela amasekethe amafushane amancane.
Ukubaleka kokushisa
Uma kwenzeka ukuqhuma kokushisa ngaphakathi kwebhethri le-lithium, kuzovela ukusabela kwamakhemikhali okushisayo phakathi kwezinto zangaphakathi zebhethri, futhi kuzokhiqizwa amagesi avuthayo njenge-hydrogen, i-carbon monoxide, ne-methane. Lokhu kusabela kuzoholela ekuphenduleni okusha okuseceleni, okwakha umjikelezo omubi, okubangela izinga lokushisa kanye nengcindezi ngaphakathi kwebhethri ukuthi kukhuphuke kakhulu, futhi ekugcineni kuholele ekuqhumeni.
Ukushaja ngokweqile isikhathi eside kweseli yebhethri
Ngaphansi kwezimo zokushaja isikhathi eside, ukushaja ngokweqile kanye nokusetshenziswa kwamandla amaningi kungaholela ekushiseni okuphezulu kanye nomfutho ophezulu, okungase kubangele izingozi zokuphepha.
Izici zangaphandle
Isekethe emfushane yangaphandle
Nakuba amasekethe amafushane angaphandle engavamile ukubangela ngqo ukuqhuma kokushisa kwebhethri, amasekethe amafushane angaphandle esikhathi eside angabangela ukuthi izindawo zokuxhuma ezibuthakathaka kusekethe zishise, okungabangela izinkinga zokuphepha ezinkulu kakhulu.
Izinga lokushisa eliphezulu langaphandle
Ngaphansi kwezimo zokushisa okuphezulu, i-electrolyte solvent yamabhethri e-lithium iyahwamuka ngokushesha, izinto ze-electrode ziyanda, futhi ukumelana kwangaphakathi kuyanda, okungase kubangele ukuvuza, imijikelezo emifushane, njll., okubangela ukuqhuma noma imililo.
Ukudlidliza noma umonakalo womshini
Uma amabhethri e-lithium evezwa ukudlidliza noma umonakalo omkhulu ngesikhathi sokuthuthwa, ukusetshenziswa noma ukulungiswa, i-diaphragm noma i-electrolyte yebhethri ingase yonakale, okuholela ekuthinteni okuqondile phakathi kwe-lithium yensimbi ne-electrolyte, okubangela ukusabela kwe-exothermic, futhi ekugcineni kuholele ekuqhumeni noma emlilweni.
Inkinga yokushaja
Ukushaja ngokweqile: Isekethe yokuvikela ayilawuleki noma ikhabhinethi yokuthola ayilawuleki, okwenza i-voltage yokushaja ibe nkulu kune-voltage elinganisiwe yebhethri, okuholela ekuqhekekeni kwe-electrolyte, ukusabela okunamandla ngaphakathi kwebhethri, kanye nokwenyuka okusheshayo kwengcindezi yangaphakathi yebhethri, okungabangela ukuqhuma.
Ugesi Oweqile: Ugesi oshaja ngokweqile ungabangela ukuthi ama-ion e-lithium angabi nesikhathi sokufaka engxenyeni ye-pole, bese kwakheka insimbi ye-lithium ebusweni bengxenye ye-pole, ingena ku-diaphragm, okubangela ukujikeleza okufushane okuqondile phakathi kwezingongolo ezinhle nezimbi kanye nokuqhuma.
Isiphetho
Izimbangela zokuqhuma kwebhethri le-lithium zifaka phakathi amasekethe amafushane angaphakathi, ukugijima kokushisa, ukushaja ngokweqile kweseli lebhethri isikhathi eside, amasekethe amafushane angaphandle, amazinga okushisa aphezulu angaphandle, ukudlidliza noma umonakalo womshini, izinkinga zokushaja, nezinye izici. Ngakho-ke, lapho usebenzisa futhi ugcina amabhethri e-lithium, kuyadingeka ukulandela ngokuqinile imithethonqubo yokuphepha efanele ukuqinisekisa ukuphepha nokuzinza kwebhethri. Ngesikhathi esifanayo, ukuqinisa ukuqapha ukuphepha kanye nezinyathelo zokuvimbela nakho kuyindlela ebalulekile yokuvimbela ukuqhuma kwebhethri le-lithium.
