Umgaqo wokudubula kunye nempazamo yentlawulo

Ukuze uvuthe ngempumelelo ibhetri ye-lithium, ii-athomu ze-lithium okanye i-ion ze-lithium kufuneka zivezwe ngokuthe ngqo kwi-oxygen. Le ndlela inokuqanjwa ukuba i-battery case yonakaliswe bubundlobongela (amandla angaphandle, umlilo ophakathi), i-overcharge okanye i-short circuit, kunye neebhetri zomgunyathi zisetyenziswa.

Makhe sijonge indlela iibhetri ze-lithium ezisebenza ngayo. Okokuqala, ii-athomu ze-lithium zigcinwa kuphela kwi-electrodes ephilileyo kunye ne-negative, kwaye amaziko afanelekileyo kunye angalunganga ahlukaniswe yi-electrolyte okanye i-electrolyte (ibhetri ye-lithium i-electrolytes; i-lithium i-electrolyte engekho-liquid). Kule meko, i-lithium izinzile kwiindawo ezisenyakatho nasezantsi. Ngokukodwa kwiibhetri ze-lithium polymer, i-lithium ikhona kwifom ye-compounds, kwaye akulula ukuyitshisa ngokuthe ngqo kwaye iqhume nangona ibonakaliswe kwi-oxygen.

Kwinkqubo yokutshaja kunye nokukhupha, imeko yebhetri iyatshintsha: iathomu ye-lithium kwi-electrode enye ilahlekelwa yi-electron, ibe yi-ion ye-lithium, ingene kwenye i-electrode nge-electrolyte ephakathi okanye i-electrolyte, kwaye utshintsho lusuka kwi-zero state ukuya kwi-athomu. urhulumente. Imeko eyingozi kakhulu yinkqubo yokufuduka kwe-lithium ion. Unokutshabalalisa ezi ion ze-lithium okanye i-electrolytes ngolu hlobo.

1, isiphaluka esifutshane

Okubizwa ngokuba yi-short circuit, ndiyakholelwa ukuba wonke umntu uyawuqonda umgaqo wayo. Xa ibhetri ye-lithium ifutshane, i-electrolyte iqala ukugcina ubushushu. Ekuqaleni, ixabiso elincinci lobushushu alibonakali liyingxaki, kodwa xa sele lishushu ngokwaneleyo, i-electrolyte iqala ukwanda kwaye i-electrolyte iqala ukutshintsha ngokuthe ngqo ukusuka kulwelo ukuya kumphunga. Emva koko, imeko embi kakhulu kukuba i-battery casing iya kuphuka, ngoko i-lithium ion ebekwe ngokutsha iya kuba isondele ngokwaneleyo kwi-oksijini, kwaye umphumo unokucingelwa.

2. Umrhumo ogqithisileyo

Umgaqo we-overcharge eyenza i-blasting ifana ne-short-circuit forming blasting, kodwa isizathu esibalulekileyo asiyiyo i-electrolyte okanye i-electrolyte, kodwa i-electrode engalunganga. Xa ibhetri ihlawuliswe ngokupheleleyo, i-athomu ye-lithium ezinzile kwi-electrode engalunganga iya kuba yintsimbi ye-lithium crystals, ingena kwi-gap phakathi kwe-electrolyte (ulwelo) kunye ne-electrode. Ngenxa yoko, intlawulo iya kudibaniswa kwi-electrode efanelekileyo, ebangela isiphaluka esifutshane sangaphakathi.

3. Ikhava yebhetri yonakele

Ungathethi, akufuneki uthembele kwi-electrolytes (i-liquids) okanye uhlawule ibhetri ngendlela ecasulayo. Ungonakalisa ibhetri ngokucofa nje kube kanye kwisingxobo sebhetri. Ke, ioksijini inokungena ebhetri kakuhle, kwaye ibhetri iya kubamba umlilo okanye iqhume ngaphambi kokuba ube nexesha lokuqhawula uvavanyo.

Nangona kunjalo, iibhetri ze-lithium zisakhuselekile

Ukuba uyoyika, yintoni umahluko phakathi kwebhetri ye-lithium kunye nendudumo kunye nokukhaba kabini? Ndifuna wazi ukuba kukho umahluko. I-Short-circuit kuqala ikhuselekile. Sineendlela ezintathu: sebenzisa ikhebula lokutshaja elingenamgangatho ukukhusela i-short-circuits yangaphandle kunye nokuthintela iindlela zokukhusela iisekhethi ezifutshane zokutshaja kwifowuni ephathekayo. Ibhetri inokunciphisa i-gap kwaye ithintele i-lithium ion ezigqithisiweyo ukuba ziqhubeke zihamba. Ngala manyathelo mathathu, ukubakho komlilo obangelwa isiphaluka esifutshane ngoku kuncinci. Ngokumalunga nokutshaja, iifowuni eziphathwayo zeempawu eziqhelekileyo ngoku zinesekhethi yokhuseleko lokutshaja, ethintela ibhetri epheleleyo ukuba ingaqhubeki nokuhlawulisa. Ke ngoko, izazinzulu kudala zizazi ezi ngozi kwaye ziseke indlela yokuvumela iibhetri ze-lithium ukuba zingene ngokuvulelekileyo kwiifowuni zethu eziphathwayo. Akunyanzelekanga ukuba sizikhathaze ngabafundi abakhulu.

Kukho enye into. Nangona imele umenzi kancinane, kufuneka sithathele ingqalelo: Amawakawaka eefowuni eziphathwayo zithunyelwa minyaka le, kwaye amathuba amancinci aya kwandiswa, ke i-iPhone yethu engaphantsi inombono onjalo, kwaye yathi Buyela ukuziqhelanisa, ubungozi bezi zinto. Iibrendi azikho phezulu kunezinye iibrendi, singasathethi ke ngokuthelekisa nezazo knockoffs. Ngaba inkxalabo yethu malunga nokhuseleko lweebhetri zeselfowuni ayiveli kwezi meko zinqabileyo?

umhlala phantsi

isenza sikholelwe ukuba sinendlela yokuvuthela ibhetri. Ke, kuthekani ukuba ufuna ukunqanda ibhetri ekuqhumeni? Okokuqala, nceda ubeke phantsi itshaja yakho jikelele! Ukutshaja jikelele kufana nokuncama ukhuseleko lwebhetri yefowuni ephathwayo. Akunakuqinisekisa kuphela ukuzinza kombane, kodwa ayiyi kunqunyulwa emva kokutshaja, kwaye iya kubangela ukugqithisa. Logama nje usebenzisa iiselfowuni ezingezizo ezomgunyathi ukuhlawulisa, oku akuyi kwenzeka.
