Amabhethri asetshenzisiwe aqukethe inani elikhulu le-nickel, i-cobalt, i-manganese nezinye izinsimbi, ezinenani eliphezulu lokugaywa kabusha. Kodwa-ke, uma bengasitholi isisombululo ngesikhathi, bazodala umonakalo omkhulu emizimbeni yabo. Imfucuzaiphakethe lebhethri le-lithium-ioninezici zobukhulu obukhulu, amandla aphezulu kanye nezinto ezikhethekile. Ngaphansi kwezinga lokushisa elithile, umswakama kanye nokuthintana kabi, kungenzeka ukuthi zishise noma ziqhume ngokuzenzakalelayo. Ngaphezu kwalokho, ukuhlakazeka nokufakwa okungenangqondo kungase kubangele ukuvuza kwe-electrolyte, isifunda esifushane, ngisho nomlilo.
Kubikwa ukuthi okwamanje, kunezindlela ezimbili eziyinhloko zokugaywa kabusha ezisetshenzisiweamabhethri e-lithium-ion: okunye ukusetshenziswa kwezigaba, okusho ukuthi ibhethri esetshenzisiwe iyaqhubeka nokusetshenziswa njengomthombo wamandla ezindaweni ezifana nokugcinwa kwamandla kagesi kanye nezimoto zikagesi ezihamba ngesivinini esincane; okwesibili ukuqaqa nokusebenzisa kabusha ibhethri elingeke lisasetshenziselwa izinjongo zokugaywa kabusha. Abanye ochwepheshe bathi ukusetshenziswa kancane kancane kungenye yezixhumanisi, futhi amabhethri e-lithium aphelile ekugcineni azodilizwa.
Ngokusobala, kungakhathaliseki ukuthi yisiphi isici okufanele sicatshangelwe, inkampani yokuvuselela ibhethri ye-lithium ekuthuthukiseni ubuchwepheshe bayo bokubola iyadingeka. Kodwa-ke, imboni iphinde yathi imboni yolwazi lwe-elekthronikhi yaseChina isencane, ubuchwepheshe obuyinhloko besixhumanisi ngasinye abuvuthwa ngokugcwele, bubhekene nezinselele ezinkulu kwezobuchwepheshe, imishini nezinye izici.
Ukugaywa kabusha kwezinhlobo ezahlukene zamabhethri kwenza kube nzima ukwenza ngokuzenzakalelayo inqubo yokudilizwa, ngaleyo ndlela kuthinte ukusebenza kahle. Abanye ochwepheshe bakholelwa ukuthi ukugaywa kabusha kwamabhethri e-lithium-ion kubhekana nezingqinamba eziningi ngenxa yobunzima bokubunjwa kwawo, kanye nezithiyo eziphezulu zobuchwepheshe.
Embonini yokusebenzisa ibhethri ye-lithium-ion echelon, ukuhlolwa kuyisisekelo, ukuhlakazeka kuyisihluthulelo, uhlelo lokusebenza luyigazi lokuphila, kanye nobuchwepheshe bokuhlola kabusha ibhethri ye-lithium-ion yisisekelo esibalulekile sokuhlakazwa, kodwa namanje ayikaphelele, njenge ukuntuleka kwezindlela zokuhlola ezingahlanganisi izimoto zamandla amasha, isikhathi eside sokuhlola, ukusebenza kahle okuphansi, njll.
Ibhodlela lobuchwepheshe lamabhethri e-lithium kadoti ngenxa yokuhlolwa kwenani lensalela nokuhlola okusheshayo kwenza kube nzima emabhizinisini agaya kabusha ukuze athole amaphethini awo okugaywa kabusha nedatha ehlobene. Ngaphandle kokusekelwa kwedatha efanele, kunzima kakhulu ukuhlola amabhethri asetshenzisiwe ngesikhathi esifushane.
Ukuba yinkimbinkimbi kwamabhethri e-lithium asusiwe nakho kuyinselelo enkulu enkampanini. Ubunkimbinkimbi bamamodeli ebhethri okuphela kwempilo, izakhiwo ezihlukene kanye nezikhala ezinkulu zobuchwepheshe kubangele izindleko eziphakeme kanye namazinga aphansi okusetshenziswa okugaywa kabusha kwebhethri nokuwaqaqa.
Izinhlobo ezahlukene zamabhethri zigaywa kabusha, okwenza ukuhlakazwa okuzenzakalelayo kube nzima kakhulu futhi ngaleyo ndlela kuholele ekwehleni kokusebenza kahle komsebenzi.
Amabhizinisi nabadlali bezimboni bafuna ukuthi kusungulwe uhlelo oluphelele lwe-lithium kanye nokuthuthukiswa kwamazinga ahambisanayo.
Lezi zinkinga zidale ukugaywa kabusha kwamabhethri e-lithium angcolile e-China kubhekene nenkinga "yezindleko eziphakeme zokudilizwa kunokulahlwa ngokuqondile". Kodwa-ke, abanye ochwepheshe bakholelwa ukuthi esinye sezizathu eziyinhloko zale nkinga engenhla ukuthi ayikho indinganiso ehlanganisiwe yamabhethri e-lithium-ion. Ngokuthuthuka okusheshayo kwemboni yaseChina yokugaywa kabusha kwebhethri ye-lithium, kunesidingo esiphuthumayo sokuthuthukisa amazinga amasha ebhethri.
Ukugaywa kabusha nokulahlwa kwamaphakethe ebhethri lamandla kadoti kuhlanganisa izixhumanisi eziningi, ezibandakanya i-physics, ikhemistri, isayensi yezinto zokwakha, ubunjiniyela kanye neminye imikhakha, inqubo iyinkimbinkimbi futhi idla isikhathi. Ngenxa yezindlela ezahlukene zobuchwepheshe kanye nezindlela zokuhlakaza ezisetshenziswa ibhizinisi ngalinye, kubangele ukuxhumana okungekuhle kwezobuchwepheshe embonini kanye nezindleko eziphezulu zobuchwepheshe.
Izinkampani nabadlali bezimboni bacele uhlelo oluphelele lwe-lithium olunamazinga ahambisanayo. Uma kunendinganiso, khona-ke kufanele kube nenqubo evamile yokudilizwa. Ngokusungula isisekelo esimisiwe, izindleko zokutshala izimali zamabhizinisi nazo zingancishiswa.
Khona-ke, ibhethri elijwayelekile le-lithium-ion kufanele lichazwe kanjani? Uhlelo olujwayelekile lokucubungula nokusetshenziswa kabusha kobuchwepheshe lwamabhethri e-lithium-ion kufanele luthuthukiswe ngokushesha okukhulu, ukwakheka okujwayelekile kanye nokudilizwa kwemininingwane yamabhethri e-lithium-ion kufanele kukhuliswe, ukukhushulwa kwamazinga ayisibopho kufanele kuqiniswe, kanye namazinga okulawula ahambisanayo. kufanele yenziwe.
