Ngokusho kwemithombo yaseJapane, i-Sumitomo Metal ithuthukise inqubo ephumelelayo yokukhipha i-cobalt kumabhethri asetshenzisiwe ezimoto zikagesi nokunye. Ubuchwepheshe buzokwenza kube nokwenzeka esikhathini esizayo ukugwema noma ukunciphisa ukushoda kwale nsimbi eyivelakancane kakhulu eMhlabeni, ngaphandle kwalokho ukwakhiwa kwamabhethri aphinde ashajwe kuyinto engacabangeki namuhla.
I-Cobalt isetshenziselwa ukwenza ama-cathodes amabhethri e-lithium-ion, ukuqinisekisa ukusebenza okuzinzile kwalezi zakhi. I-Sumitomo Metal, isibonelo, ithola insimbi ene-cobalt evela eNingizimu-mpumalanga ye-Asia. Le nkampani icubungula i-ore ukuze ikhiphe i-cobalt eJapan, ngemuva kwalokho inikeze insimbi emsulwa kubakhiqizi bebhethri njengePanasonic nezinye izinkampani ezihlinzeka ngamabhethri e-United States ezimotweni zakwaTesla.
Cishe i-60% ye-cobalt imbiwa eDemocratic Republic of the Congo. Izinkampani zaseMelika nezaseSwitzerland zinezimayini eCongo, kodwa eminyakeni yamuva nje ziye zathengwa ngamaShayina. Ngakho, ngo-2016, iMolybdenum yaseShayina yathenga ingxenye enkulu yamasheya enkampanini iTenke Fungurume enkampanini yaseMelika iFreeport-McMoRan, ephethe izimayini ze-cobalt eCongo, kwathi ngo-2017 inkampani yakwaGEM yaseShanghai yathenga izimayini eSwitzerland. Glencore. Ukukhawulela iziza zezimayini ze-cobalt, abahlaziyi bakholelwa ukuthi, kuzoholela ekushodeni kwale nsimbi ekuqaleni kuka-2022, ngakho-ke i-cobalt yezimayini evela ezintweni ezigaywe kabusha ingase iphushele lesi sikhathi esingesihle siye phambili.
Ukutadisha amathuba enqubo entsha yobuchwepheshe yokukhipha i-cobalt kumabhethri asetshenzisiwe, i-Sumitomo Metal yaqala ukumisa imboni yokuhlola e-Ehime Prefecture e-Shikoku Island. Inqubo ehlongozwayo ivumela i-cobalt ukuthi itholakale ngokushesha ngendlela ehlanzekile ngokwanele ukuze ibuyiselwe ngokushesha kubakhiqizi bebhethri. Ngendlela, ngaphezu kwe-cobalt, ithusi ne-nickel kuzophinde kukhishwe ngesikhathi senqubo yokuvuselela ibhethri, okuzofaka kuphela izinzuzo zendlela entsha. Uma ukukhiqizwa komshayeli wendiza kubonakala kusebenza kahle, iSumitomo Metal izoqala ukucubungula amabhethri ukuze kukhishwe i-cobalt ngo-2021.
