CATL ta yi alfahari da karya shingen 0,3 kWh / kg don ƙwayoyin lithium-ion.
Wannan ba shine labarai na ƙarshe na ƙarshe ba, amma mun yanke shawarar cewa idan aka ba da yawan kamfanonin da ke aiki tare da CATL, yana da daraja ambato. To, kamfanin da ke kera kwayoyin lithium-ion na kasar Sin ya sanar da cewa ya shawo kan shingen makamashi mai karfin kilowatt 0,3 na kowace kilogiram na kwayoyin halitta. An samar da daidai 0,304 kWh/kg, wanda a halin yanzu rikodin duniya ne.
Fasahar Amperex ta kasar Sin ta zamani (CATL) tana kan gaba a yawan adadin kwayoyin lithium-ion da aka samar. Koyaya, imanin cewa ƙwayoyin Sinawa sun yi ƙasa da na Koriya ta Kudu LG Chem, Samsung SDI, ko SK Innovation ya ci gaba. Kamfanin yana ƙoƙari akai-akai don yaƙar wannan ra'ayi.
Fiye da shekara guda da rabi da suka wuce, CATL ta yi alkawarin batir 57kWh a cikin BMW i3 - godiya ga ƙananan ƙwayoyin cuta. Yanzu an yabe shi don ƙirƙirar tantanin halitta lithium-ion tare da ƙarfin ƙarfin 0,304 kWh/kg. Bugu da ƙari: leaks akan wannan batu ya riga ya bayyana a tsakiyar 2018. An sami babban ƙarfin makamashi mai yawa godiya ga nickel-rich (Ni) cathode da graphite-silicon (C, Si) anode - ya zuwa yanzu an yi la'akari da mafi kyawun sakamakon Tesla, wanda ya kai matakin kusan 0,25 kWh / kg:
Har ila yau, ya kamata a lura da cewa lokacin amfani da fasaha iri ɗaya, ƙwayoyin da ke cikin jaka (ƙasa dama) suna da ƙarfin makamashi mafi girma. Kuma duk godiya ga gidaje masu ƙarfi da manyan lambobin sadarwa (kasa, tsakiya), waɗanda suke auna nauyi don wannan iko.
Ba a sani ba ko an riga an samar da su da yawa kuma ko ana gabatar da sabbin abubuwa. Ya zuwa yanzu, kawai wani mataki na ci gaba da aka cimma a cikin bincike da ci gaba.
