Ukuhlaziywa kwembangela nezixazululo zezinkinga ezivamile zebhethri ye-lithium ion

Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ububanzi kanye nendima yeamabhethri e-lithiumSekuyisikhathi eside zibonakala, kodwa ekuphileni kwethu kwansuku zonke, izingozi zebhethri ze-lithium zihlala zivela ngokungapheli, okuhlala kusihlupha.Ngenxa yalokhu, umhleli uhlela ngokukhethekile i-lithium Ukuhlaziywa kwezimbangela zezinkinga ezivamile ze-ion nezixazululo, ngithemba ukukunikeza lula.

1. I-voltage ayihambisani, futhi eminye iphansi

1. Ukuzikhipha okukhulu kubangela i-voltage ephansi

Ukuzikhipha kweseli kukhulu, ukuze i-voltage yayo yehle ngokushesha kunabanye.I-voltage ephansi ingaqedwa ngokubheka i-voltage ngemuva kokugcinwa.

2. Ukushaja okungalingani kubangela i-voltage ephansi

Uma ibhethri lishajwa ngemva kokuhlolwa, iseli yebhethri ayishajwa ngokulinganayo ngenxa yokumelana nokuxhumana okungahambisani noma amandla okushaja ekhabhinethi yokuhlola.Umehluko we-voltage olinganisiwe mncane ngesikhathi sokugcinwa kwesikhashana (amahora angu-12), kodwa umehluko we-voltage mkhulu ngesikhathi sokugcina isikhathi eside.Le voltage ephansi ayinazo izinkinga zekhwalithi futhi ingaxazululwa ngokushaja.Igcinwe amahora angaphezu kwama-24 ukukala i-voltage ngemva kokushajwa ngesikhathi sokukhiqiza.

Okwesibili, ukumelana kwangaphakathi kukhulu kakhulu

1. Umehluko emishinini yokuhlonza udalwe

Uma ukunemba kokutholwa kunganele noma iqembu loxhumana nabo lingakwazi ukususwa, ukumelana kwangaphakathi kwesibonisi kuzoba kukhulu kakhulu.Umgomo wendlela yebhuloho le-AC kufanele usetshenziselwe ukuhlola ukumelana kwangaphakathi kwethuluzi.

2. Isikhathi sokugcina side kakhulu

Amabhethri e-lithium agcinwa isikhathi eside kakhulu, okubangela ukulahlekelwa amandla ngokweqile, ukudlula kwangaphakathi, nokumelana okukhulu kwangaphakathi, okungaxazululwa ngokushaja nokuvula ukusebenza.

3. Ukushisa okungavamile kubangela ukumelana okukhulu kwangaphakathi

Ibhethri lishiswa ngendlela engavamile ngesikhathi sokucubungula (i-spot welding, i-ultrasonic, njll.), okwenza i-diaphragm ikhiqize ukuvala okushisayo, futhi ukumelana kwangaphakathi kwanda kakhulu.

3. Ukunwetshwa kwebhethri ye-lithium

1. Ibhethri ye-lithium iyakhukhumala lapho ishajwa

Lapho ibhethri ye-lithium ishajwa, ibhethri ye-lithium izokhula ngokwemvelo, kodwa ngokuvamile ingabi ngaphezu kuka-0.1mm, kodwa ukukhokhiswa ngokweqile kuzobangela ukubola kwe-electrolyte, ukucindezela kwangaphakathi kuzokwanda, futhi ibhethri ye-lithium izokhula.

2. Ukunwetshwa ngesikhathi sokucubungula

Ngokuvamile, ukucutshungulwa okungavamile (okufana nokujikeleza okufushane, ukushisa ngokweqile, njll.) kubangela ukuba i-electrolyte ibole ngenxa yokushisisa ngokweqile, futhi ibhethri ye-lithium iyavuvukala.

3. Nweba ngenkathi uhamba ngebhayisikili

Uma ibhethri lijikeleziswa, ukushuba kuzokwanda ngokunyuka kwenani lemijikelezo, kodwa ngeke kwande ngemva kwemijikelezo engaphezu kuka-50.Ngokuvamile, ukwanda okuvamile kungu-0.3~0.6 mm.Igobolondo le-aluminium libucayi kakhulu.Lesi simo sibangelwa ukusabela kwebhethri okuvamile.Kodwa-ke, uma ukushuba kwegobolondo kwanda noma izinto zangaphakathi zincishiswa, into yokwandisa ingancishiswa ngokufanelekile.

Okwesine, ibhethri linamandla aphansi ngemva kokushiselwa kwendawo

I-voltage yeseli yegobolondo le-aluminium ngemva kokushisela indawo ingaphansi kuka-3.7V, ngokuvamile ngenxa yokuthi indawo yokushisela icishe yephule i-diaphragm yangaphakathi yeseli kanye nama-short-circuits, okubangela ukuba ugesi wehle ngokushesha kakhulu.

Ngokuvamile, kubangelwa indawo yokushisela engalungile.Indawo efanele yokushisela indawo kufanele ibe ukushisela indawo phansi noma ohlangothini olunophawu “A” noma “—”.I-Spot welding ayivunyelwe ohlangothini nohlangothi olukhulu ngaphandle kokumaka.Ngaphezu kwalokho, amanye amateyipu e-nickel ane-welded ane-weldability empofu, ngakho-ke kufanele abe ne-spot-welded nge-current enkulu, ukuze itheyiphu yangaphakathi yokumelana nokushisa ingakwazi ukusebenza, okuholela ku-short-circuit yangaphakathi ye-core yebhethri.

Ingxenye yokuphelelwa amandla ebhethri ngemva kokushiselwa kwendawo kungenxa yokuzikhipha okukhulu kwebhethri ngokwalo.

Eyesihlanu, ibhethri liyaqhuma

Ngokuvamile, kunezimo ezilandelayo lapho ukuqhuma kwebhethri kwenzeka:

1. Ukuqhuma kwe-overcharge

Uma isifunda sokuvikela singalawuleki noma ikhabhinethi yokuhlonza ingalawuleki, i-voltage yokushaja inkulu kuno-5V, okubangela ukubola kwe-electrolyte, ukusabela okunobudlova kwenzeka ngaphakathi kwebhethri, ukucindezela kwangaphakathi kwebhethri kukhuphuka ngokushesha, futhi ibhethri liyaqhuma.

2. Ukuqhuma kwe-Overcurrent

Isekhethi yokuvikela ayilawuleki noma ikhabhinethi yokuhlonza ingaphandle kokulawula, ukuze ukushaja kube kukhulu kakhulu futhi ama-ion e-lithium aphuze kakhulu ukushumeka, futhi insimbi ye-lithium yakheka ebusweni besiqephu sesigxobo, ingena ngaphakathi i-diaphragm, kanye nama-electrode aqondile kanye nama-negative afinyezwa ngokuqondile futhi abangele ukuqhuma (akuvamile).

3. Ukuqhuma lapho igobolondo lepulasitiki lishisela i-ultrasonic

Lapho i-ultrasonic i-welding igobolondo lepulasitiki, amandla e-ultrasonic adluliselwa kumgogodla webhethri ngenxa yemishini.Amandla e-ultrasonic makhulu kangangokuthi i-diaphragm yangaphakathi yebhethri iyancibilika, futhi ama-electrode aqondile nama-negative afinyezwa ngokuqondile, abangele ukuqhuma.

4. Ukuqhuma ngesikhathi sokushisela indawo

Ukwanda kwamandla ngesikhathi sokushisela indawo kubangele umjikelezo ongathi sína wangaphakathi obangele ukuqhuma.Ukwengeza, ngesikhathi sokushisela indawo, ucezu oluxhumayo lwe-electrode oluqondile lwaluxhunywe ngokuqondile ku-electrode engalungile, okwenza izigxobo ezinhle nezingezinhle ukuthi zifinyezeke ngokuqondile futhi ziqhume.

5. Ukuqhuma kokukhipha okungaphezulu

Ukuchichima ngokweqile noma ukuchichima okweqile (ngaphezulu kuka-3C) kwebhethri kuzoncibilika kalula futhi kufake ucwecwe lwe-electrode yethusi olunegethivu kusihlukanisi, okubangele ukuthi ama-electrode aphozithivu noma anegethivu abe yimfushane ngokuqondile futhi abangele ukuqhuma (akuvamile ukwenzeka).

6. Phuma lapho ukudlidliza kwehla

Ucezu lwesigxobo lwangaphakathi lwebhethri luyasuswa lapho ibhethri lidlidliza noma liwa, futhi liyafinyezwa ngokuqondile futhi liqhume (akuvamile).

Okwesithupha, inkundla yebhethri engu-3.6V iphansi

1. Ukusampula okungalungile kwekhabhinethi yokuthola noma iKhabhinethi yokuthola engazinzile kubangele ukuthi inkundla yokuhlola ibe phansi.

2. Izinga lokushisa eliphansi le-ambient lidala ipulatifomu ephansi (ipulatifomu yokukhipha amanzi ithintwa kakhulu izinga lokushisa le-ambient)

Eziyisikhombisa, ezibangelwa ukucubungula okungafanele

(1) Hambisa ucezu oluhlanganisayo lwe-electrode ephozithivu yokushisela indawo ngamandla ukuze ubangele ukuthintana kahle kwe-electrode ephozithivu yeseli yebhethri, okwenza ukumelana kwangaphakathi kwengqikithi yebhethri kukhulu.

(2) Indawo yokuxhuma i-welding ayihlanganisiwe ngokuqinile, futhi ukumelana nokuxhumana kukhulu, okwenza ibhethri ukumelana kwangaphakathi kube kukhulu.
