Isingeniso:
Ibhethri ye-lithiumibhethri esebenzisa i-lithium metal noma i-lithium compound njenge-electrode material. Ngenxa yesikhulumi se-voltage ephezulu, isisindo esilula nempilo ende yesevisi ye-lithium, ibhethri ye-lithium isibe uhlobo oluyinhloko lwebhethri elisetshenziswa kabanzi ku-electronics yabathengi, izinhlelo zokugcina amandla, izimoto zikagesi nezinye izinkambu. Namuhla, ake sihlole izinyathelo ezimbalwa zokugcina zokwenziwa kwebhethri ye-lithium, i-Formation-OCV testcapacity-Separation.
Ukwakheka
Ukwakhiwa kwebhethri ye-lithium kuyinqubo yokuqala yokushaja yebhethri ngemva kokuba ibhethri ye-lithium igcwaliswe ngoketshezi.
Le nqubo ingenza kusebenze izinto ezisebenzayo ebhethrini bese ivulaibhethri ye-lithium. Ngesikhathi esifanayo, usawoti we-lithium uhlangana ne-electrolyte ukwakha ifilimu eqinile ye-electrolyte interface (SEI) ohlangothini lwe-electrode engalungile yebhethri ye-lithium. Le filimu ingavimbela ukuvela okuqhubekayo kokusabela ohlangothini, ngaleyo ndlela yehlise ukulahlekelwa kwe-lithium esebenzayo kubhethri ye-lithium. Izinga le-SEI linomthelela omkhulu empilweni yomjikelezo, ukulahleka kwamandla okuqala, nokusebenza kwezinga lamabhethri e-lithium.
Ukuhlolwa kwe-OCV
Ukuhlolwa kwe-OCV ukuhlolwa kwe-voltage yesekethe evulekile, ukumelana kwangaphakathi kwe-AC kanye ne-voltage yegobolondo yeseli eyodwa. Kuyingxenye ebaluleke kakhulu yenqubo yokukhiqiza ibhethri. Idinga ukuhlangabezana nokunemba kwe-OCV kuka-0.1mv kanye nokunemba kwegobolondo legobolondo elingu-1mv. Ukuhlolwa kwe-OCV kusetshenziselwa ukuhlunga amaseli.
Inqubo yokukhiqiza yokuhlola ye-OCV
Ukuhlolwa kwe-OCV kukala izici zebhethri ngokucindezela ama-probe axhunywe kusihloli se-voltage kanye nesihloli sangaphakathi sokumelana ezindlebeni eziphozithivu nezinegethivu zebhethri lephakethe elithambile.
Ukuhlolwa kwamanje kwe-OCV ngokuyinhloko kuwukuhlola okuzenzakalelayo. Isisebenzi sibeka ibhethri mathupha kudivayisi yokuhlola, futhi i-probe yedivayisi yokuhlola ixhumene nezindlebe zebhethri eziphozithivu nezinegethivu ukuze senze ukuhlola kwe-OCV ebhethrini, bese siyikhipha mathupha futhi siyihlunga ibhethri.
Ukuhlukaniswa kwamandla ebhethri ye-lithium
Ngemva kwenqwaba yeamabhethri e-lithiumzenziwe, nakuba ubukhulu bufana, amandla amabhethri azohluka. Ngakho-ke, kufanele zikhokhiswe ngokugcwele kumishini ngokusho kwemininingwane, bese zikhishwa (zikhishwe ngokuphelele) ngokuvumelana nomthamo oshiwo. Isikhathi esithathwayo ukuze kukhishwe ibhethri, siphindwe ngokugcwele amandla ebhethri.
Uma nje umthamo ohloliwe uhlangana noma udlula umthamo oklanyelwe, ibhethri ye-lithium ifanelekile, futhi ibhethri elingaphansi komthamo oklanyelwe alikwazi ukubhekwa njengebhethri elifanelekayo. Le nqubo yokukhetha amabhethri aqeqeshiwe ngokuhlola umthamo ibizwa ngokuthi ukuhlukaniswa kwamandla.
Indima yeibhethri ye-lithiumukuhlukaniswa kwamandla akusizi nje kuphela ukuzinza kwefilimu ye-SEI, kodwa futhi kunganciphisa isikhathi esidliwe yinqubo yokuhlukanisa amandla, ukunciphisa ukusetshenziswa kwamandla nokwandisa umthamo wokukhiqiza.
Enye inhloso yokuhlukaniswa kwamandla iwukuhlukanisa nokuhlanganisa amabhethri, okungukuthi, ukukhetha ama-monomers anokumelana okufanayo kwangaphakathi namandla okuhlanganiswa. Uma uhlanganisa, yilabo kuphela abanokusebenza okufanayo abangakha iphekhi yebhethri.
Isiphetho
Ekugcineni, iibhethri ye-lithiumiqedele zonke izinqubo zeseli yebhethri ngemva kokuhlolwa okugcwele kokubukeka, ukufafaza kwekhodi yebanga, ukuhlolwa kokuskena kwebanga, nokupakishwa, okulinde ukuqoqwa kuphakethe lebhethri.
Mayelana namaphakethe ebhethri, uma unombono wamaphakethe ebhethri e-DIY, i-Heltec ihlinzekaizihloli zamandla ebhethriukukuvumela ukuthi uqonde amapharamitha ebhethri lakho futhi ucabangele ukuthi ikulungele yini ukuhlanganisa iphakethe lebhethri olifunayo. Siphinde sihlinzekeisilinganisi sebhethriukugcina amabhethri akho amadala futhi ulinganise amabhethri nokushajwa okungalingani kanye nokukhipha ukuze kuthuthukiswe ukusebenza kahle kwebhethri nempilo.
I-Heltec Energy inguzakwethu omethembayo ekukhiqizeni amaphakethe ebhethri. Ngokugxila kwethu ngokungaphezi ocwaningweni nasekuthuthukisweni, kuhambisana nohlu lwethu olubanzi lwezinsiza zebhethri, sinikeza izixazululo zokuma okukodwa ukuze sihlangabezane nezidingo eziguqukayo zomkhakha. Ukuzibophezela kwethu ekwenzeni okuhle, izixazululo eziklanyelwe, kanye nokusebenzisana okuqinile kwamakhasimende kusenza sibe yinketho kubakhiqizi baphakethe lebhethri nabahlinzeki emhlabeni jikelele.
Uma unemibuzo noma ungathanda ukufunda okwengeziwe, sicela ungangabazifinyelela kithi.
