Isingeniso:
Amabhethri e-lithiumsesiyingxenye ebalulekile yokuphila kwethu kwansuku zonke, sinikeza amandla yonke into kusukela kuma-smartphones nama-laptops kuya ezimotweni zikagesi nezinhlelo zokugcina amandla. Amabhethri e-lithium asetshenziswa kakhulu, kodwa kube nezigameko zokusha nokuqhuma, okuthi nakuba kungavamile, okuye kwaveza ukukhathazeka ngokuphepha kwawo. Ukuqonda izici ezingase ziholele ezenzakalweni ezinjalo kubalulekile ekuqinisekiseni ukusetshenziswa okuphephile nokuthembekile kwamabhethri e-lithium.
Ukuqhuma kwebhethri ye-lithium kuyinkinga ebucayi yokuphepha, futhi izimbangela zokuvela kwazo ziyinkimbinkimbi futhi ziyahlukahluka, ikakhulukazi ezihlanganisa izici zangaphakathi nezangaphandle.
Izici zangaphakathi
Isifunda esifushane sangaphakathi
Umthamo we-electrode ongemuhle onganele: Uma umthamo we-electrode ongemuhle we-electrode ephozithivu yebhethri ye-lithium unganele, ama-athomu e-lithium akhiqizwa ngesikhathi sokushaja awakwazi ukufakwa esakhiweni se-interlayer se-graphite ye-electrode eyinegethivu, futhi azokwehla phezu kwe-electrode eyinegethivu. ukwakha amakristalu. Ukuqoqwa kwesikhathi eside kwalawa makristalu kungase kubangele ukujikeleza okufushane, iseli yebhethri iphume ngokushesha, ikhiqize ukushisa okukhulu, ishise i-diaphragm, bese idala ukuqhuma.
Ukumuncwa kwamanzi e-Electrode nokusabela kwe-electrolyte: Ngemva kokuba i-electrode imunca amanzi, ingase isabele nge-electrolyte ukuze ikhiqize amaqhuqhuva omoya, okungase kubangele amasekhethi amafushane angaphakathi.
Izinkinga ze-Electrolyte: Ikhwalithi nokusebenza kwe-electrolyte ngokwayo, kanye nenani loketshezi olujovwe phakathi nomjovo olungahlangabezani nezidingo zenqubo, kungase kuthinte ukuphepha kwebhethri.
Ukungcola enqubweni yokukhiqiza: Ukungcola, uthuli, njll. okungenzeka kube khona phakathi nenqubo yokukhiqiza ibhethri nakho kungabangela amasekhethi amafushane amancane.
Ukubaleka okushisayo
Lapho ukuphuma kwe-thermal kwenzeka ngaphakathi kwebhethri ye-lithium, ukusabela kwamakhemikhali e-exothermic kuzokwenzeka phakathi kwezinto zangaphakathi zebhethri, futhi kuzokhiqizwa amagesi avuthayo njenge-hydrogen, i-carbon monoxide, ne-methane. Lokhu kusabela kuzoholela ekuphenduleni okusha okusemaceleni, kwakhe umjikelezo ononya, okubangela izinga lokushisa nokucindezela ngaphakathi kwebhethri kukhuphuke kakhulu, futhi ekugcineni kuholele ekuqhumeni.
Ukushajwa ngokweqile kwesikhathi eside kweseli yebhethri
Ngaphansi kwezimo zokushaja zesikhathi eside, ukushaja ngokweqile kanye ne-overcurrent kungase futhi kuholele ekushiseni okuphezulu nokucindezela okukhulu, okungase kubangele izingozi zokuphepha.
Izici zangaphandle
Isifunda esifushane sangaphandle
Nakuba amasekethe amafushane angaphandle engavamile ukuthi abangele ukushisa kwebhethri ngokuqondile, amasekhethi amafushane angaphandle esikhathi eside angase abangele ukuthi izindawo zokuxhuma ezibuthakathaka ezisesekethe zishise, okungase kubangele izinkinga ezinkulu zokuphepha.
Izinga lokushisa langaphandle eliphezulu
Ngaphansi kwezindawo zokushisa eziphakeme, i-electrolyte solvent yamabhethri e-lithium iyahwamuka ngokushesha, izinto ze-electrode zanda, futhi ukumelana kwangaphakathi kuyanda, okungabangela ukuvuza, izifunda ezimfushane, njll, okubangela ukuqhuma noma imililo.
Ukudlidliza komshini noma ukulimala
Lapho amabhethri e-lithium engaphansi kokudlidliza okuqinile komshini noma ukulimala ngesikhathi sokuhamba, ukusetshenziswa noma ukulungiswa, i-diaphragm noma i-electrolyte yebhethri ingalimala, okuholela ekuxhumaneni okuqondile phakathi kwe-lithium yensimbi ne-electrolyte, kubangele ukusabela kwe-exothermic, futhi ekugcineni kuholele ekuqhumeni noma ekuqhumeni. umlilo.
Inkinga yokushaja
Ukushajwa okweqile: Isekhethi yokuvikela ayilawuleki noma ikhabhinethi yokubona ayisekho ekulawuleni, okubangela ukuthi i-voltage yokushaja ibe nkulu kune-voltage elinganiselwe yebhethri, okuholela ekuwohlokeni kwe-electrolyte, ukusabela okunobudlova ngaphakathi kwebhethri, nokukhuphuka ngokushesha kwangaphakathi. ukucindezela kwebhethri, okungabangela ukuqhuma.
I-Overcurrent: Ukushaja okweqile kungadala ukuthi i-lithium ion ingabi naso isikhathi sokushumeka esiqeshini se-lithium, futhi insimbi ye-lithium yakheka phezu kocezu lwesigxobo, ingene ku-diaphragm, ibangele ukujikeleza okufushane okuqondile phakathi kwezigxobo ezinhle nezimbi kanye nokuqhuma. .
Isiphetho
Izimbangela zokuqhuma kwebhethri ye-lithium zihlanganisa izifunda ezimfushane zangaphakathi, ukugijima okushisayo, ukushaja okweqile kwebhethri yesikhathi eside, izifunda ezimfushane zangaphandle, izinga lokushisa eliphezulu langaphandle, ukudlidliza kwemishini noma ukulimala, izinkinga zokushaja, nezinye izici. Ngakho-ke, lapho usebenzisa futhi ugcina amabhethri e-lithium, kubalulekile ukuthobela imithetho efanele yokuphepha ukuze uqinisekise ukuphepha nokuzinza kwebhethri. Ngesikhathi esifanayo, ukuqinisa ukugadwa kokuphepha kanye nezinyathelo zokuvimbela nazo ziyizindlela ezibalulekile zokuvimbela ukuqhuma kwebhethri ye-lithium.
I-Heltec Energy inguzakwethu omethembayo ekukhiqizeni amaphakethe ebhethri. Ngokugxila kwethu ngokungaphezi ocwaningweni nasekuthuthukisweni, kuhambisana nohlu lwethu olubanzi lwezinsiza zebhethri, sinikeza izixazululo zokuma okukodwa ukuze sihlangabezane nezidingo eziguqukayo zomkhakha. Ukuzibophezela kwethu ekwenzeni okuhle, izixazululo eziklanyelwe, kanye nokusebenzisana okuqinile kwamakhasimende kusenza sibe yinketho kubakhiqizi baphakethe lebhethri nabahlinzeki emhlabeni jikelele.
