Yunivesite ya Chalmers ya Ukadaulo ku Sweden ikunena za njira yatsopano yobwezeretsanso mabatire amagetsi. Njirayi siifuna mankhwala okwera mtengo kapena oopsa chifukwa ofufuzawo adagwiritsa ntchito oxalic acid, asidi wachilengedwe wopezeka muufumu wa zomera.
Malinga ndi yunivesite, njirayi imatha kubweza 100% ya aluminiyamu ndi 98% ya lithiamu kuchokera ku mabatire amagetsi. Izi zimachepetsanso kutayika kwa zinthu zamtengo wapatali monga nickel, cobalt ndi manganese.
Ku Chalmers University's Battery Recycling Laboratory, gulu linayesa kukonza zinthu zakuda, zomwe ndi ufa wosakaniza wa zinthu zofunika kwambiri m'mabatire, mu oxalic acid. Makamaka, tinkalankhula za batire yamagetsi ya Volvo. Kalatayo ikufotokoza njira imeneyi ngati "kupanga khofi." Ndipotu, chilichonse chimakhala chovuta kwambiri, chifukwa kuti njira ya oxalic acid ipange zotsatira zomwe mukufuna, ndikofunikira kusankha bwino kutentha, kuchuluka kwake, ndi nthawi yake. Mwa njira, oxalic acid imapezeka m'zomera monga rhubarb ndi sipinachi.
"Mpaka pano, palibe amene wapeza zinthu zoyenera kulekanitsa lithiamu yambiri chonchi pogwiritsa ntchito oxalic acid ndikuchotsa aluminiyamu yonse. Popeza mabatire onse ali ndi aluminiyamu, tiyenera kutha kuichotsa popanda kutaya zitsulo zina," akutero Leah Rouquette, wophunzira womaliza maphunziro mu dipatimentiyi.
Mu njira zomwe zimagwiritsidwa ntchito pano za hydrometallurgical, zinthu zachitsulo zimasungunuka mu ma inorganic acid. "Zodetsa" monga aluminiyamu ndi mkuwa zimachotsedwa ndipo zinthu zogwira ntchito monga cobalt, nickel, manganese ndi lithiamu zimabwezedwanso, motsatana.
Komabe, ofufuza aku Sweden akuwona kuti ngakhale aluminiyamu ndi mkuwa wotsala pang'ono zimafunika njira zingapo zoyeretsera, ndipo gawo lililonse la njirayi lingayambitse kutayika kwa lithiamu. Pogwiritsa ntchito njira yatsopanoyi, ofufuzawo adasintha dongosololi ndikuchepetsa lithiamu ndi aluminiyamu kaye. Izi zimawathandiza kuchepetsa kutayika kwa zitsulo zamtengo wapatali zofunika popanga mabatire atsopano.
Gawo lotsatira lingathenso kuyerekezeredwa ndi kupanga khofi: pamene aluminiyamu ndi lithiamu zili mumadzimadzi, zitsulo zotsalazo zimakhalabe mu "cholimba". Gawo lotsatira mu njirayi ndikulekanitsa aluminiyamu ndi lithiamu. "Popeza zitsulozi zili ndi makhalidwe osiyana kwambiri, sitikuganiza kuti zidzakhala zovuta kuzilekanitsa. Njira yathu ndi njira yatsopano yodalirika yobwezeretsanso mabatire yomwe ndiyofunika kuifufuza mozama," adatero Rouquette.
"Tikufuna njira zina m'malo mwa mankhwala osapangidwa ndi zinthu zachilengedwe. Chimodzi mwa zopinga zazikulu zomwe zikuchitika masiku ano ndi kuchotsa zinthu zotsalira monga aluminiyamu. Iyi ndi njira yatsopano yomwe ingapereke njira zina zatsopano m'makampani oyendetsera zinyalala ndikuthandizira kuthetsa mavuto omwe akulepheretsa kukula," adatero pulofesa wa dipatimentiyi. Martina Petranikova Komabe, adawonjezera kuti njirayi ikufunika kafukufuku wowonjezera: "Popeza njira iyi ikhoza kukulitsidwa, tikukhulupirira kuti ingagwiritsidwe ntchito m'makampani m'zaka zikubwerazi."
Kuyambira mu 2011, takhala tikufalitsa nkhani zokhudza chitukuko cha magalimoto amagetsi ndi chidwi komanso ukadaulo wa atolankhani. Monga atolankhani otsogola kwambiri mumakampaniwa, timapereka nkhani zapamwamba kwambiri komanso zodzaza ndi zochitika, zomwe zimagwira ntchito ngati nsanja yayikulu yopititsira patsogolo ukadaulo uwu mwachangu. Zimaphatikizapo nkhani, zambiri zakumbuyo, malipoti oyendetsa galimoto, zoyankhulana, makanema ndi zambiri zotsatsira.
