Ngabe ibhethri le-lithium-ion liyakhokhisa kanjani futhi likhiphe?

Amabhethri e-Lithium-Ion athandwa ngabantu abaphakeme bamandla aphezulu, impilo ende yokujikeleza, kanye nezinga eliphansi lokuzikhulula. Ukuqonda ukuthi la mabhethri asebenza kanjani kubalulekile.

Izingxenye zebhethri ze-lithium-ion

Izakhi eziyisisekelo zebhethri le-lithium-ion zifaka i-anode, i-cathode, i-electrolyte, kanye ne-ahlukanisi. Lezi zinto zisebenza ngokubambisana ukugcina nokukhipha amandla kahle. I-anode imvamisa yenziwe ngegrafu, ngenkathi i-cathode iqukethe i-lithium metal oxide. I-electrolyte yisixazululo sikasawoti se-lithium kwi-organic solvent, futhi ohlukanisayo ulwelwesi oluncane oluvimbela amasekethe amafushane ngokugcina i-anode ne-cathode ehlukaniswe ngayo.

Inqubo yokukhokhisa nenqubo yokuphuma

Izinqubo zokushaja nezinto zokulahla zamabhethri e-lithium-ion zibalulekile ekusebenzeni kwazo. Lezi zinqubo zibandakanya ukunyakaza kwama-lithium ion phakathi kwe-anode ne-cathode ngokusebenzisa i-electrolyte.

Inqubo yokushaja

Lapho kushaywa izindleko zebhethri ze-lithium-ion, ama-lithium ion asuka e-cathode eya e-anode. Lokhu kunyakaza kwenzeka ngoba umthombo wamandla kagesi wangaphandle, usebenzisa i-voltage kuwo wonke ama-terminals ebhethri. Leli voltage lishayela ama-lithium ion nge-electrolyte naku-anode, lapho agcinwa khona. Inqubo yokushaja ingadilizwa ibe yizigaba ezimbili eziyinhloko: isigaba se-Constant samanje (CC) kanye nesigaba seVoltage Voltage (CV).

Ngesikhathi sesigaba se-CC, okwamanje kunikezwa ibhethri, okwenza ukuthi ivolula likhuphuke kancane kancane. Lapho ibhethri lifinyelela umkhawulo walo omkhulu we-voltage, i-Charger ishintshela esigabeni se-CV. Kulesi sigaba, i-voltage ibanjwa njalo, futhi kancane kancane kuyancipha kuze kube yilapho ifinyelela inani elincane. Okwamanje, ibhethri likhokhiswa ngokuphelele.

Inqubo yokukhipha

Ukukhipha ibhethri le-lithium-ion kufaka phakathi inqubo yokubuyela emuva, lapho i-lithium ion isuka e-anode ibuyele e-cathode. Lapho ibhethri lixhunyiwe kudivayisi, idivaysi idonsa amandla kagesi ebhethri. Lokhu kudala ukuthi ama-lithium ion ashiye i-anode futhi ahambe nge-electrolyte e-cathode, akhiqiza ugesi wamanje onamandla okunika amandla idivaysi.

Ukusabela kwamakhemikhali ngesikhathi sokuhlanza empeleni kungukubuyiselwa kwalabo ngesikhathi sokushaja. I-Lithium Ion ihlangana (faka) kwizinto ze-cathode, kanti ama-elektroni ahamba ngokujikeleza kwangaphandle, anikeze amandla kudivayisi exhunyiwe.

Lokhu kuphendula kugcizelela ukudluliswa kwama-lithium ion kanye nokugeleza okuhambisanayo kwama-elektroni, okuyisisekelo ekusebenzeni kwebhethri.

Izici zebhethri ze-Lithium-Ion

Amabhethri e-Lithium-Ion ayaziwa ngezimpawu zawo ezithile, njengokuqina kwamandla aphezulu, ukuzimela okuphansi, impilo ende yomjikelezo. Lezi zimfanelo zizenza zilungele izinhlelo zokusebenza lapho amandla ahlala njalo aqakathekile. Amamenyu asemqoka ambalwa asetshenziselwa ukuhlola amabhethri e-lithium-ion:

Ubuningi bamandla: Kukala inani lamandla agcinwe ngevolumu enikeziwe noma isisindo.

Impilo Yomjikelezo: Ibonisa inani lemijikelezo yokushaja ibhethri lingangena ngaphambi kokuba umthamo walo ungcolise kakhulu.

I-C-Rate: ichaza izinga lapho ibhethri likhokhiswa khona noma likhishwe isihlobo salo esiphezulu.

Ukubaluleka kokuqapha ukushaja nokukhipha

Ukuqapha imali ekhokhwayo kanye nemijikelezo yokukhipha amabhethri e-lithium-ion kubalulekile ukuze kuqinisekiswe isikhathi eside nokuphepha kwabo. Ukweqisa noma ukudilizwa okujulile kungaholela ekulimaleni kwebhethri, umthamo oncishisiwe, kanye nezingozi zokuphepha ezinjenge-traway eshisayo. Ukuqapha okusebenzayo kusiza ekugcinweni kokusebenza kahle futhi kunwebe isikhathi sokuphila kwebhethri. Izisombululo zokuqapha ezithuthukisiwe ezifana I-DFUN EMAHHALA yokuhlola ibhethri idlala indima ebalulekile ekuqapheleni nasekuphatheni inqubo yokukhokhisa neyokulahlwa. Uhlelo luqopha ukushaja okuphelele nesimo sokudilizwa, sibala umthamo wangempela, futhi siqinisekise ukuthi ipakethe lebhethri eliphelele lihlala lisebenza kahle futhi liphephile ukulisebenzisa.
