Ngowama-2025, umlinganiselo weemveliso zegrafiti ezinokuphinda zisetyenziswe kulindeleke ukuba unyuke ukusuka kwi-15% ngo-2023 ukuya kwi-25%, nto leyo emisela inkqubo evaliweyo "yokuvelisa-ukuphinda kusetyenziswe-ukuhlaziywa."
Ukusasazwa Okukhawulezileyo Komthamo Wokuphinda Usetyenziswe
UBobang Shanhe uqalise isigaba sokuqala seprojekthi yokuvuselela umgangatho ophezulu yeetoni ezingama-20,000 zeetoni zee-anode zegrafiti yenkunkuma, ngelixa iCATL ityale imali kumgca wokuqala wemveliso yobuninzi bokuphinda kusetyenziswe izixhobo zegrafiti yenkunkuma, ifikelela kwizinga lokuphinda kusetyenziswe elingaphezulu kwama-90%. Ngowama-2025, umthamo uwonke wee-anode zegrafiti yenkunkuma ezifuna ukuphinde kusetyenziswe kulindeleke ukuba udlule kwiitoni ezili-150,000, kunye nezinga lokukhula lonyaka elihlanganisiweyo (CAGR) lama-40%, nto leyo ebonisa amandla amakhulu emarike.
III. Imingeni yoShishino: Ukulawula iiWorkshops ezincinci kunye nokungabikho kweMigangatho
Inxalenye Ephezulu Yokusetyenziswa Kabutsha Okungekho Sikweni
Imarike yokusetyenziswa kwakhona kweebhetri ze-lithium-ion ibisoloko ilawulwa ziiworkshop ezincinci, ezithatha i-70% yeli candelo. Ukudilizwa okungekho mthethweni kukhokelela ekuvuthweni kwee-carcinogens (umz., ii-nickel compounds) kunye nezinto ezirhabaxa (umz., i-hydrogen fluoride), nto leyo ebeka umngcipheko kwindalo esingqongileyo nakwimpilo yabantu. Ishishini lokusetyenziswa kwakhona kwee-electrode ze-graphite lijongene nemiba efanayo, apho izinto ze-graphite eziphinda zisetyenziswe ngokungesesikweni zibonisa umgangatho ongaguqukiyo kwaye zingaphumeleli ukuhlangabezana neemfuno zokusetyenziswa okuphezulu.
