Ibhethri ye-lithium enezinga lokushisa elibanzingokuvamile ibhekisela ekushiseni okuphezulu kwamabhethri e-lithium-ion, ngakho-ke uma kwenzeka ukuqhuma ngesikhathi sokusetshenziswa, kuzoba namuphi umphumela ebhethrini? Siyazi ukuthi iseli yebhethri imvamisa ibhethri le-ternary lithium. Futhi manje kukhona amangqamuzana amaningi ahlukene, njengamanye amabhethri ethu avamile e-ternary lithium asetshenziswa i-graphite negative electrode, lolu hlobo lwezinto ezibonakalayo ze-electrode engalungile, amabhethri e-lithium ayisisekelo asetshenziswa impahla ye-lithium cobaltate ye-electrode enhle. Ngakho izinga lokushisa elibanzi lebhethri le-lithium lizoqhuma ngaphansi kwezinga lokushisa eliphakeme eliqhubekayo? Lapha ukwabelana nawe ngemibono efanele.
Njengezinto ezisetshenziswa kumaseli ebhethri amanje, okuhlanganisa amabhethri e-ternary lithium-ion yi-lithium cobaltate, i-lithium iron phosphate nezinye izinto zokwenza i-electrode enhle. Ngakho-ke ibhethri ye-ternary lithium ekushiseni okuphansi lapho amathuba okuqhuma mancane kakhulu. Kodwa iningi lemakethe yamanje yokushisa okubanzi amabhethri e-lithium azosebenzisa i-lithium cobaltate njenge-electrode enhle. Futhi i-lithium iron phosphate isekelwe ku-ternary lithium ukwenza i-electrode engalungile; futhi i-lithium cobaltate iwukwenza i-electrode enhle; kanye ne-ternary lithium ion ukwenza i-electrode engalungile kune-electrode eqondile. Lokhu kuholela ekushintsheni kwesakhiwo sayo sebhethri.
Ukuxazulula inkinga yokuphepha kwamabhethri e-lithium okushisa okubanzi, ukhiye uwukuthuthukisa ukuphepha. Okokuqala, ingqamuzana yebhethri kufanele ilawulwe ngokuqinile, okuyisiqinisekiso sokusebenza kwebhethri futhi ingagwema ngempumelelo isifunda esifushane sangaphakathi noma ukushajwa ngokweqile ngesikhathi sokusebenza kwebhethri, kanye nokuvimbela ukuvela kokushisa kwangaphakathi okuphezulu kwebhethri. , okuholela ekuqhumeni kwebhethri. Futhi ekusebenziseni kwansuku zonke kufanele futhi unake impilo ephephile yebhethri futhi ugweme ukushisa kwebhethri, ukushajwa ngokweqile nezinye izimo. Okulandelayo, kufanele sinake umthelela wezinga lokushisa ebhethrini. Izinga lokushisa lebhethri liphezulu kakhulu ukuze siphephe impilo yethu nakho kuzoba usongo. Ngakho-ke, uma imikhiqizo yebhethri ifuna ukusetshenziswa kangcono ekuphileni kwethu kwansuku zonke, kufanele futhi sinake umsebenzi wokulawula izinga lokushisa kwebhethri.
Ngokombono wokuphepha, lapho izinga lokushisa lebhethri liphezulu kakhulu, amabhethri e-lithium-ion angenzeka into evuthayo evuthayo. Lokhu kungenxa yokuthi i-ion ye-lithium equkethwe ebhethri ye-lithium-ion yakhiwa ikakhulukazi amaconsi awuketshezi, amaconsi amaningi awuketshezi, izinga lokushisa eliphakeme lebhethri ye-lithium-ion, uma i-ion ye-lithium ekufudukeni ngokweqile kwe-electrolyte, ukusakazeka kuzokwenza i-lithium ion ukufuduka okungahlehliseki okuholela ekushiseni okuzenzakalelayo kwe-short-circuit, njll.. Ngaphezu kwalokho, ibhethri esikhathini eside sokusebenza kwezinga lokushisa eliphezulu okunganqamuki lingase libangele ukubola kwempahla yebhethri kanye nomsebenzi wehla, ngaleyo ndlela kusheshiswe ukujikeleza okufushane okuholela ngaphakathi. umlilo webhethri noma ukuqhuma. Ngakho-ke, ngombono wokuphepha, ukusetshenziswa kwamabhethri e-lithium-ion okushisa aphezulu kufanele kuvaliwe ngesikhathi esifanele. Ngaphezu kwalokho, uma izinga lokushisa liphezulu kakhulu, kulula ukubangela i-short-circuiting yangaphakathi futhi ngaleyo ndlela kubangele umlilo nokuqhuma. Ukwengeza, lapho ubuka ukuphepha kwebhethri lamandla, uma kungenjalo ukuhlola okuphelele kokuphepha kanye nokusetshenziswa kwebhethri ye-lithium-ion okungenzeka iqhume.
Eqinisweni, izinga lokushisa elibanzi lebhethri le-lithium liphephe kakhudlwana ukulisebenzisa ngoba lihlangabezana nezidingo zokuphepha zamabhethri e-lithium-ion ku-GB18483-2001 Safety Technical Specification for Lithium-ion Batteries, ehambisana kakhulu nezindinganiso zokuphepha. Kodwa ngenxa yokuthi umkhiqizo omusha, awekho amazinga acacile kazwelonke namazinga emboni ukuze aqondise ukuthuthukiswa kwalobu buchwepheshe, ngakho-ke sidinga ukuhlanganisa ukusetshenziswa kokuqonda okuthile. Enkambweni yokusetshenziswa kudingeka ugweme ukuthintana nokushisa okuphezulu, ugesi omile, ukukhishwa ngokweqile, ukukhishwa kanye nezinye izici eziyingozi, ngaphandle kwalokho kulula ukubangela ukuqhuma okuyinhloko. Ngakho ekusetshenzisweni kwansuku zonke kufanele kunake ukusetshenziswa okuphephile kwamabhethri e-lithium okushisa okubanzi kanye nokugcinwa okuphephile nokusetshenziswa.
Okungenhla kumayelana nokuthi izinga lokushisa elibanzi lebhethri le-lithium lizoqhuma yini kanye nokuqukethwe okuhlobene nebhethri ye-lithium ebanzi.
