Maererano nezvinyorwa zveJapan, Sumitomo Metal yakagadzira nzira inoshanda yekubvisa cobalt kubva kumabhatiri akashandiswa emotokari dzemagetsi nezvimwe. Iyo tekinoroji ichaita kuti mune ramangwana zvibvire kudzivirira kana kuderedza kushomeka kweiyi isingawanzo simbi paPasi, pasina iyo kugadzirwa kwemabhatiri anochajiswa hazvifungike nhasi.
Cobalt inoshandiswa kugadzira cathodes ye lithium-ion mabhatiri, kuve nechokwadi chekushanda kwakagadzikana kwezvinhu izvi. Sumitomo Metal, semuenzaniso, inopa cobalt-inotakura ore kubva kuSoutheast Asia. Kambani inobata ore kuburitsa cobalt muJapan, yozopa simbi yakachena kune vanogadzira mabhatiri sePanasonic nemamwe makambani anopa mabhatiri muUnited States emotokari dzeTesla.
Inenge 60% yecobalt inocherwa muDemocratic Republic of the Congo. Makambani eAmerica neSwiss ane migodhi muCongo, asi mumakore achangopfuura akatengwa neChina. Nekudaro, muna 2016, iyo Chinese Molybdenum yakatenga chikamu chakakosha chechikamu chekambani yeTenke Fungurume kubva kuAmerican kambani Freeport-McMoRan, iyo ine migodhi yecobalt kuCongo, uye muna 2017 kambani yeGEM kubva kuShanghai yakatenga migodhi kubva kuSwitzerland. Glencore. Kudzikamisa nzvimbo dzemigodhi yecobalt, vanoongorora vanotenda, kuchatungamira kushomeka kwesimbi iyi kutanga kwa2022, saka migodhi yecobalt kubva kune yakadzokororwa inogona kusundira iyi inosuruvarisa nguva mberi mune ramangwana.
Kudzidza zvingangoitika zvehunyanzvi hwekuita tekinoroji yekubvisa cobalt kubva kumabhatiri akashandiswa, Sumitomo Metal yakatanga kumisa chirimwa chekutyaira muEhime Prefecture paShikoku Island. Maitiro akatsanangurwa anobvumira cobalt kuti ikurumidze kudzoserwa mune yakakwana fomu yakachena kuitira kuti igone kudzoserwa pakarepo kune vanogadzira bhatiri. Nenzira, kuwedzera kune cobalt, mhangura uye nickel ichabudiswawo panguva yebhatiri recycling process, iyo inongowedzera kune zvakanakira nzira itsva. Kana kugadzirwa kwemutyairi kukaratidza kushanda, Sumitomo Metal ichatanga kutengeserana kugadzirisa mabhatiri kuti abvise cobalt muna 2021.
