Yunivesiti ya Chalmers yaku Sweden yaamba nzila mpya yakubelesya mabbattery aamyootokala yamagesi. Nzila eeyi taiyandiki misamu iidula naakuti iikola nkaambo basikuvwuntauzya bakabelesya oxalic acid, asidi uujanika muzisyango.
Nzila eeyi ilakonzya kujana 100% ya aluminiyamu a 98% ya lithium kuzwa kumabbatili aamyootokala yamagesi, kweendelanya a yunivesiti. Eezi zipa kuti kutabi kusweekelwa zintu ziyandisi zilimbuli nickel, cobalt antoomwe a manganese.
Ku Chalmers University's Battery Recycling Laboratory, kabunga kakasola kubamba zintu zisiya, musamu uusanganizidwe wazintu ziyandikana zibeleka mumabbattery, mu oxalic acid. Mubwini, twakali kwaambuula aatala abbattery lyamota yamagesi ya Volvo. lugwalo lupandulula nzila eeyi kuti "kupanga kkofi." Mubunike, zyoonse zilakatazya loko, nkaambo kuchitila kuti nzila ya oxalic acid ichite mpindu, kuyandika kusala kabotu-kabotu kupya, bunji achiindi. Mpawo, oxalic acid ilajanwa muzisyango zilimbuli rhubarb a spinach.
"Kusikila lino, taakwe wakakonzya kujana nzila zibotu zyakwaandaanya lithiyamu mpati loko kubelesya oxalic acid akugwisya aluminiyamu yoonse. Nkaambo kakuti mabbattery woonse alijisi aluminiyamu, tweelede kuti tukonzye kugwisya kakunyina kusweekelwa zimwi nsimbi." wakaamba chemistry yaku yunivesiti, wakapandulula Leah Rouquette, sikwiiya uumanizya chikolo muchibeela eechi.
Munzila zya hydrometallurgic zibelesyegwa lino, zintu zijisi butale zilanyonyooka muma asidi aatakwe buumi. "Busofweede" mbuli aluminiyamu a copper mpawo bulagwisigwa mpawo zintu zibeleka mbuli cobalt, nickel, manganese a lithium zilajanwa, kweendelana.
Nokuba boobo, basikuvwuntauzya baku Sweden baamba kuti nikuba tuniini twa aluminiyamu amukuba tuyandika ntaamu zyiingi zyakusalazya, mpawo ntaamu imwi aimwi mumulimo ooyu ilakonzya kupa kuti lithium isweekelwe. Kubelesya nzila mpya, basikuvwuntauzya bakasandula nzila mpawo bakasaanguna kuchesya lithium aaluminiyamu. Eezi zipa kuti bachinche kusowa zintu ziyandisi ziyandikana mukupanga mabbattery mapya.
Ntaamu itobela ilakonzya kweezyanisyigwa akujika kkofi: aawo aluminiyamu a lithium nozili mumaanzi, insimbi zisyeede zilazumanana kuba "muchintu chiyumu". Ntaamu itobela mumulimo ooyu nkwaandaanya aluminiyamu a lithiyamu. "Nkambo kakuti eezi nsimbi zili abube bwiindene, tatuyeeyi kuti inga tiikwaba penzi kwaandaanya. Nzila yesu ninzila mpya iisyomya yakubelesya mabbattery lubo eeyo yeelede kuvwuntauzyigwa," Rouquette wakaamba.
"Tuyanda nzila zimbi zyakubelesya mubusena bwamakemikalu aatakwe buumi. Chimwi chazintu zipati zitulesya mumilimo yamazubaano nkugwisya zintu zyakasyaala zilimbuli aluminiyamu. Eeyi ninzila mpya iikonzya kupa nzila zipya zyakubelesya mumakwebo aakulanganya tombe akugwasya kumanizya mapenzi aalesya kukomena," wakaamba mufundisi wamuchibeela. Martina Petranikova Nokuba boobo, wakayungizya kuti nzila eeyi iyandika buvwuntauzi bumbi: "Mbwaanga nzila eeyi ilakonzya kuyaambele, tulangila kuti ilakonzya kubelesegwa mumakwebo muminyaka iiboola."
Kuzwa mu 2011, twakali kwaambilizya zyakupanga myootokala yamagesi aluyandisisyo lwabasikumwaya makani. Mbuli basikumwaya makani basololela mumulimo ooyu, tulapa makani aali kabotu kapati, aamba zyoonse zicitika, akubeleka mbuli nzila mpati yakusumpula nzila eeyi. Zibikkilizya makani, makani aakaindi, malipooti aakweenzya, mibuzyo, mavidiyo amakani aakusumpula.
