Isingeniso:
Ibhethri le-lithiumIbhethri elisebenzisa i-lithium Metal noma i-lithium compact njengezinto ze-electrode. Ngenxa yesikhulumi se-voltage ephezulu, isisindo esikhanyayo kanye neLithium Service Life of Lithium, ibhethri le-Lithium selibe uhlobo oluphambili lwebhethri olusetshenziswa kabanzi kwi-Consumer Electronics, amasistimu okugcina amandla, izimoto zikagesi kanye nezinye izinkambu. Namuhla, ake sihlole izinyathelo ezimbalwa zokugcina zokukhiqiza ibhethri le-Lithium, i-Accoment-OCV testcapacity-dearration.
Ukwakheka
Ukwakheka kwebhethri le-Lithium kuyinqubo yokuqala yokushaja yebhethri ngemuva kwebhethri le-lithium ligcwele uketshezi.
Le nqubo ingasebenza izinto ezisebenzayo ebhethri futhi isebenzeibhethri le-lithium. Ngasikhathi sinye, usawoti we-lithium uhlangabezana ne-electrolyte ukwakha i-electrolyte eqinile ye-electrolyte interface (sei) ifilimu elingesihle se-elektrodi sebhethri le-lithium. Le filimu ingavimba ukuvela okuqhubekayo kokuphendula okukhulu, ngaleyo ndlela kunciphisa ukulahleka kwe-lithium esebenzayo yebhethri le-lithium. Ikhwalithi ye-SEI inethonya elikhulu empilweni yomjikelezo, ukulahleka kwamandla okuqala, kanye nokusebenza kwezinga lamabhethri e-lithium.
Ukuhlolwa kwe-OCV
Ukuhlolwa kwe-OCV ukuvivinya kwe-Open Circuity Voltage, ukumelana kwangaphakathi kanye ne-Shell Voltage yeseli elilodwa. Kuyingxenye ebaluleke kakhulu yenqubo yokukhiqiza yebhethri. Idinga ukufeza ukunemba kwe-OCV kwe-0.1MV kanye nokunemba kwe-Shell Voltage ukunemba kwe-1MV. Ukuhlolwa kwe-OCV kusetshenziselwa ukuhlunga amaseli.
Inqubo yokukhiqiza yokuhlola ye-OCV
Ukuhlolwa kwe-OCV ikakhulukazi kukala izici zebhethri ngokucindezela izinghloliso ezixhumeke kumhloli we-voltage kanye nomhloli wokumelana wangaphakathi ezindlebeni ezingezinhle zebhethri elinamahloni nezimbi zebhethri elinemininingwane ethambile nelibi lebhethri elinemininingwane ethambile.
Ukuhlolwa kwamanje kwe-OCV ikakhulukazi ukuhlolwa okuzenzakalelayo okuzenzakalelayo. Isisebenzi sibeka ibhethri ngesandla kudivayisi yokuhlola, futhi ukuphenya kwensiza yokuhlola kuthintana nezindlebe ezinhle nezimbi zebhethri ukwenza ukuhlolwa kwebhethri, bese kuthulula ngesandla futhi kuhlunga ibhethri.
I-Lithium yebhethri yebhethri
Ngemuva kwe-batch yeamabhethri e-lithiumzenziwe, yize ubukhulu bufana, umthamo wamabhethri uzohluka. Ngakho-ke, kumele zikhokhiswe ngokugcwele kwimishini ngokuya ngezincazelo, bese idedelwa (ikhishwe ngokuphelele) ngokuya ngentengo ebekiwe. Isikhathi esithathiwe sokukhipha ibhethri siphindaphindwe ngokuphelele yi-Decumps yamanje yikhono lebhethri.
Uma nje umthamo ohlolwe uhlangabezana noma weqa umthamo owenzelwe, ibhethri le-lithium lifanelekile, futhi ibhethri elinokungaphansi komthamo oklanyelwe alinakubhekwa njengebhethri elifanelekile. Le nqubo yokukhetha amabhethri afanelekayo ngokuhlolwa kwamandla abizwa ngokuthi ukwehlukaniswa kwamakhono.
Indima yeibhethri le-lithiumUkuhlukaniswa kwamakhono akusona kuphela ukuqina kwefilimu ye-SEI, kepha futhi kunganciphisa isikhathi esidliwe yinqubo yokuhlukanisa amandla, ukunciphisa ukusetshenziswa kwamandla futhi kukhuphule amandla okukhiqiza.
Enye injongo yokuhlukaniswa kwamakhono ukuhlukanisa nokuhlanganisa amabhethri, okungukuthi, ukukhetha ama-monomers anokumelana kwangaphakathi okufanayo kanye namandla okuhlanganiswa. Lapho uhlanganisa, yilabo kuphela abasebenza ngokufana kakhulu abangakha iphakethe lebhethri.
Ukugcina
Ekugcineni,ibhethri le-lithiumUqede zonke izinqubo zeseli lebhethri ngemuva kokuhlolwa okugcwele kokubukeka, ukufafaza ikhodi yebanga, ukuhlolwa kokuskena kwebanga, nokupakisha, ukulinda ukuhlanganiswa kwiphakethe lebhethri.
Mayelana namaphakethe ebhethri, uma unombono wamaphakethe webhethri we-DIY, i-Heltec ihlinzekaAbahloli bebhethriUkuvumela ukuthi uqonde amapharamitha wakho webhethri futhi ubheke ukuthi kufanelekile yini ukuhlanganisa iphakethe lebhethri oyifunayo. Siphinde futhi sinikezeIsilinganisi sebhethriUkuze ulondoloze amabhethri akho amadala futhi alinganise amabhethri anecala elingalingani nokukhululwa ukuthuthukisa ukusebenza kwebhethri nokuphila.
IHeltec Energy ngumlingani wakho othembekile ekukhiqizweni kwebhethri yebhethri. Ngokugxila kwethu ngokungapheli kokucwaninga nasekuthuthukisweni, okuhambisana nobubanzi bethu obubanzi bezesekeli zebhethri, Sinikeza izixazululo zokumisa eyodwa ukuze uhlangabezane nezidingo zalo mbombo. Ukuzibophezela kwethu ekusebenzeni kahle, izixazululo ezihambisana nakho, kanye nokubambisana kwamakhasimende okuqinile kusenza sikwazi ukukhetha abakhiqizi bebhethri bebhethri nabaphakeli emhlabeni jikelele.
Uma unemibuzo noma ungathanda ukufunda okuningi, sicela ungangabazifinyelela kithi.
