Ibhethri ye-lithium cobalt oxide, eyaziwa nangokuthi ibhethri ye-LCO, iwuhlobo lwebhethri ye-lithium-ion ethole ukuthandwa kabanzi eminyakeni yamuva nje. Lolu hlobo lwebhethri lunikeza ukuminyana kwamandla aphezulu, impilo yomjikelezo omude, nokusebenza okuhle kakhulu ngaphansi kwamazinga okushisa aphezulu, okulenza lifaneleke kuhlelo olubanzi lwezinhlelo zokusebenza. Kulesi sihloko, sizoxoxa ngokucaciswa nokusetshenziswa kwamabhethri e-lithium cobalt oxide.

Imininingwane yebhethri ye-lithium cobalt oxide

Amabhethri e-lithium cobalt oxide ngokuvamile akhiwa i-cathode eyenziwe nge-lithium cobalt oxide, i-anode eyenziwe nge-graphite, kanye ne-electrolyte eyakhiwe usawoti we-lithium oncibilike ku-solvent yemvelo. I-cathode iyingxenye ebaluleke kakhulu yebhethri, njengoba inesibopho sokugcina amandla. I-Lithium cobalt oxide yaziwa ngokuminyana kwayo okuphezulu, okuyenza ibe ukukhetha okudumile ukusetshenziswa kumabhethri.

Umthamo othize wamabhethri e-lithium cobalt oxide ngokuvamile awu-140-160 mAh/g, okusho ukuthi angagcina inani elibalulekile lamandla uma kuqhathaniswa nesisindo sawo. I-voltage yokusebenza yamabhethri e-lithium cobalt oxide ngokuvamile icishe ibe ngu-3.7-4.2 volts, ephakeme uma iqhathaniswa nezinye izinhlobo zamabhethri e-lithium-ion.

Izinhlelo zokusebenza zebhethri ze-lithium cobalt oxide

Amabhethri e-lithium cobalt oxide avame ukusetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa izinto zikagesi ezithengwayo, izimoto zikagesi, nezinhlelo zokugcina amandla ezimile. Kuma-electronics abathengi, amabhethri e-lithium cobalt oxide asetshenziselwa ukunika amandla ama-smartphones, amakhompyutha aphathekayo, namanye amadivaysi aphathekayo ngenxa yokuminyana kwawo okuphezulu nempilo yomjikelezo omude.

Embonini yezimoto, amabhethri e-lithium cobalt oxide asetshenziselwa ukunika amandla izimoto zikagesi ngenxa yekhono lazo lokuletha amandla aphezulu nokugcina ukusebenza kwazo isikhathi eside. Amasistimu okugcina amandla amile, njengalawo asetshenziselwa ukugcinwa kwamandla elanga, ajwayele ukusebenzisa amabhethri e-lithium cobalt oxide ngenxa yekhono lawo lokugcina amandla amaningi kanye nempilo yawo yomjikelezo omude uma kuqhathaniswa.
