Ngokwezindaba ezikhishwe uMnyango Wezokwazisa Nge-elekthronikhi woMnyango Wezimboni Nobuchwepheshe Bolwazi ngoDisemba 10, ukuze kuqhutshekwe nokuqinisa ukuphathwa kwemboni yebhethri ye-lithium-ion futhi kugqugquzelwe ukuguqulwa nokuthuthukiswa kwemboni kanye nenqubekela phambili yezobuchwepheshe, UMnyango Wezimboni Nobuchwepheshe Bolwazi uphathe okwesikhashana “Izimo Zezimo Zemboni Yebhethri Ye-Lithium-ion” kanye “Nesimemezelo Sesimemezelo Semboni Yebhethri Ye-Lithium-ion” Izinyathelo zibuyekeziwe futhi ziyamenyezelwa."Imibandela Yezimo Zemboni Yebhethri ye-Lithium-ion (Ushicilelo lwango-2018)" kanye "Nezinyathelo Zesikhashana Zokuphathwa Kwezimemezelo Zezinqumo Zemboni Yebhethri ye-Lithium-ion (Ushicilelo luka-2018)" (Isimemezelo No. 5, 2019 Somnyango Wemboni Nobuchwepheshe Bolwazi ) izochithwa ngesikhathi esifanayo.
"Izimo ezijwayelekile zemboni yebhethri ye-Lithium-ion (2021)" iphakamisa ukuqondisa izinkampani ukuze zinciphise amaphrojekthi okukhiqiza avele andise umthamo wokukhiqiza, aqinise ukuqanjwa kabusha kwezobuchwepheshe, athuthukise ikhwalithi yomkhiqizo, futhi anciphise izindleko zokukhiqiza.Izinkampani zebhethri ye-lithium-ion kufanele zihlangabezane nalezi zimo ezilandelayo: e-People's Republic of China zibhaliswe ngokusemthethweni futhi zasungulwa ezweni, ezinobuntu obusemthethweni obuzimele;ukukhiqiza okuzimele, ukuthengisa kanye namakhono wesevisi wemikhiqizo ehlobene embonini yebhethri ye-lithium-ion;Izindleko ze-R&D azikho ngaphansi kuka-3% wemali engenayo yebhizinisi eyinhloko yonyaka, futhi izinkampani zikhuthazwa ukuthi zithole izikhungo ezizimele ze-R&D ezingeni lesifundazwe noma ngaphezulu Iziqu zezikhungo zobuchwepheshe noma amabhizinisi zobuchwepheshe obuphezulu;imikhiqizo eyinhloko inamalungelo obunikazi bokusungulwa kwezobuchwepheshe;umkhiqizo wangempela wonyaka odlule ngesikhathi sokumenyezelwa akufanele ube ngaphansi kuka-50% wamandla okukhiqiza wangempela wonyaka ofanayo.
“Izimo ezijwayelekile zemboni yebhethri ye-Lithium-ion (2021)” futhi idinga ukuthi izinkampani zisebenzisa ubuchwepheshe obuthuthukisiwe, ukonga ugesi, ukungavumelani nendawo ezungezile, okuphephile nezinzile, kanye nezinqubo zokukhiqiza ezihlakaniphe kakhulu nezinto zokusebenza, futhi zihlangabezane nalezi zidingo ezilandelayo: 1. I-Lithium-ion izinkampani zebhethri kufanele zibe Ikhono lokuqapha ukufana kwe-electrode ngemva kokumbozwa, futhi ukunemba kokulawula kokuqina nobude be-electrode abukho ngaphansi kuka-2μm no-1mm ngokulandelana;kufanele ibe nobuchwepheshe bokumisa i-electrode, futhi ukunemba kokulawula okuqukethwe kwamanzi akufanele kube ngaphansi kuka-10ppm.2. Izinkampani zebhethri ye-lithium-ion kufanele zibe namandla okulawula izimo zemvelo ezifana nezinga lokushisa, umswakama kanye nokuhlanzeka ngesikhathi sokujova;kufanele babe nekhono lokuthola ukuhlola kwangaphakathi kwe-short-circuit high-voltage (HI-POT) ku-inthanethi ngemva kokuhlanganiswa kwebhethri.3. Amabhizinisi ephakethe lebhethri ye-lithium-ion kufanele abe nekhono lokulawula i-voltage yesekethe evulekile kanye nokumelana kwangaphakathi kwamaseli angawodwa, futhi ukunemba kokulawula akufanele kube ngaphansi kuka-1mV no-1mΩ ngokulandelana;kufanele babe nekhono lokuhlola umsebenzi webhodi lokuvikela iphakethe lebhethri ku-inthanethi.
Ngokusebenza komkhiqizo, "Izimo Zezimo Zemboni Yebhethri Ye-Lithium-ion (Uhlelo Lwango-2021)" zenze lezi zidingo ezilandelayo:
