intengo yebhethri ye-lithium cobalt oxide kanye ne-lithium cobalt oxide ibhethri ye-electrolyte
Ibhethri ye-lithium cobalt oxide, eyaziwa nangokuthi ibhethri ye-LCO, iwuhlobo lwebhethri ye-lithium-ion esetshenziswa kakhulu kumadivayisi ahlukahlukene kagesi, njengama-smartphones, amalaptop, namakhamera edijithali. Yaziwa ngobuningi bayo bamandla aphezulu, isisindo esingasindi, kanye nempilo yomjikelezo omude. Kodwa-ke, intengo yamabhethri e-LCO ingaba phezulu kakhulu ngenxa yezindleko zezinto ezingavuthiwe ezisetshenziswa ekukhiqizeni kwayo, futhi i-electrolyte esetshenziswa ebhethrini iyingxenye ebalulekile edlala indima ebalulekile ekusebenzeni nasekuphepheni kwayo.
Okokuqala, ake sikhulume ngentengo yebhethri ye-lithium cobalt oxide. Izindleko zamabhethri e-LCO zingahluka ngokuya ngezinto ezifana nesidingo semakethe, amanani wezinto ezingavuthiwe, nezinqubo zokukhiqiza. I-Cobalt, enye yezingxenye eziyinhloko zamabhethri e-LCO, iyimpahla eluhlaza ebiza kakhulu. Intengo ye-cobalt ibilokhu iguquguquka eminyakeni yamuva, okuholela ekushintshashintsheni kwentengo yamabhethri e-LCO. Ngaphezu kwalokho, izindleko zokukhiqiza amabhethri e-LCO nazo zingaba phezulu kunezinye izinhlobo zamabhethri e-lithium-ion ngenxa yobunzima benqubo yokukhiqiza.
Manje, ake sidlulele ku-electrolyte esetshenziswa kubhethri ye-lithium cobalt oxide. I-electrolyte iyingxenye ebalulekile ebhethrini eqhuba ama-ion e-lithium phakathi kwama-electrode amahle noma angalungile phakathi nemijikelezo yokushaja nokukhipha. I-electrolyte esetshenziswa kakhulu kumabhethri e-LCO inhlanganisela kasawoti we-lithium kanye ne-solvent ephilayo. Kodwa-ke, kunokukhathazeka okuthile kokuphepha okuhlobene nokusetshenziswa kwezinyibilikisi eziphilayo ezivuthayo, futhi zingase zingazinzi emazingeni okushisa aphezulu. Ngakho-ke, abacwaningi bahlola ukusetshenziswa kwama-electrolyte aphephile futhi azinzile, njengama-solid state electrolyte.
Sengiphetha, intengo yebhethri ye-lithium cobalt oxide ingaba phezulu ngenxa yezindleko zezinto ezingavuthiwe nezinqubo zokukhiqiza. I-electrolyte esetshenziswe ebhethrini iyingxenye ebalulekile edlala indima ebalulekile ekusebenzeni nasekuphepheni kwayo. Nakuba i-electrolyte evame ukusetshenziswa kakhulu inokukhathazeka okuthile kokuphepha, abacwaningi basebenzela ukuthuthukisa ama-electrolyte aphephile futhi azinzile ukuze asetshenziswe kumabhethri e-LCO. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe kanye nokwandiswa kwezicelo, kulindeleke ukuthi intengo yamabhethri e-LCO izokwehla, kuyilapho ukusebenza nokuphepha kwabo kuzoqhubeka ngcono.
