Ngenxa yobuningi bamandla amabhethri e-lithium-ion, ukuzinza okushisayo okuphansi kwezinto ezinhle nezingezinhle, kanye ne-electrolyte evuthayo ye-organic electrolyte, amabhethri e-lithium-ion angase abe nezinkinga ezinkulu zokuphepha ngaphansi kwezimo ezithile, njengamazinga okushisa aphezulu noma zavutha zaqhuma.Kunezizathu eziningi zezinkinga zokuphepha zamabhethri e-lithium-ion, njengokulimala kwemishini, ukulimala kwemvelo, ukulimala kukagesi, nokungazinzi kwawo.Kungakhathaliseki imbangela yezinkinga zokuphepha zamabhethri e-lithium-ion, izingozi zokuphepha ezivezwa amabhethri e-lithium-ion ekugcineni zihambisana nama-short-circuits angaphakathi nangaphandle aholela ekukhuphukeni okubukhali kwezinga lokushisa noma ngisho nomlilo nokuqhuma, okungukuthi, inkinga yokubaleka okushisayo kwamabhethri e-lithium-ion.
Ngokusetshenziswa okukhulu kwamabhethri e-lithium-ion emkhakheni wezimoto zikagesi kanyeukugcinwa kwamandla, amamojula ebhethri asetshenziswa ezimotweni zikagesi ngokuvamile amakhulu kakhulu.Uma ukushisa kungakwazi ukushajwa ngaphandle kwemojuli yebhethri ngesikhathi ngenxa yezizathu zedizayini noma ukwehluleka kwesistimu yokupholisa, iseli elilodwa noma amaningi awodwa ngaphakathi kwemojuli izokwakha ukunqwabelana kokushisa.Uma izinga lokushisa lebhethri ligcina lifinyelele izinga lokushisa elishisayo, ibhethri lingavuza noma ishise, noma libangele ukuthi ibhethri liqhume.Isimangaliso esikhulu sokubaleka kwayo yonke isistimu yebhethri okubangelwa ukubaleka okushisayo kwamabhethri e-lithium-ion ukunwetshwa kokubaleka okushisayo kwamabhethri e-lithium-ion.Ngomthamo omkhulu, amamojula webhethri ye-lithium-ion enamandla amakhulu, izinkinga zokuphepha zigqama nakakhulu.Ngenxa yokuthi ukwanda kokushisa okushisayo kwenzeka kumamojula amakhulu ebhethri ye-lithium-ion, kunzima kakhulu ukucisha umlilo, okuvame ukubangela ukulimala kanye nokulahlekelwa okukhulu kwezomnotho, futhi umthelela mkhulu kakhulu.
Ngokusho kwemiphumela yokuhlolwa, umthamo wokushisa othize weibhethri ye-lithium ion ye-ternarykanye nebhethri ye-lithium iron phosphate lithium ion esetshenziswa ngokuyisisekelo iyafana.Esivivinyweni esinwetshiwe sokushisa okushisayo, ngemva kokuba imojuli yebhethri ye-lithium-ion ye-ternary ibangele ukubaleka kokushisa kwebhethri elilodwa, amabhethri asele abhekana nokugijima okushisayo ngokushintshana, futhi abonise ukujwayelekile okuthile ekuthuthukisweni kwe-thermal runaway;i-lithium iron phosphate Ukunwetshwa okushisayo kwemojuli yebhethri ye-ion kuhlulekile ukwenzeka.Ngemva kokucupha ukubaleka kokushisa kwebhethri elilodwa, amabhethri asele awazange abe nokuphuma kokushisa.Ngemuva kwamahora angu-3 okushisa okuqhubekayo, ukugijima okushisayo akuzange kwenzeke.Ibhethri ye-lithium ion ye-ternary ibamba umlilo futhi ivutha ngamandla lapho ukushisa kungalawuleki, futhi amandla akhululwayo aphezulu kunalawo ebhethri ye-lithium iron phosphate lithium ion.
