Kaminuza y’ikoranabuhanga ya Chalmers muri Suwede yatangaje uburyo bushya bwo kongera gukoresha bateri z’amashanyarazi. Ubu buryo ntibusaba imiti ihenze cyangwa yangiza kuko abashakashatsi bakoresheje aside oxalic, aside organic iboneka mu bwami bw’ibimera.
Iyi gahunda ishobora kugarura 100% bya aluminiyumu na 98% bya lithiyumu bivuye muri bateri z'imodoka zikoresha amashanyarazi, nk'uko kaminuza ibivuga. Ibi kandi bigabanya igihombo cy'ibikoresho fatizo by'agaciro nka nikeli, kobalti na manganese.
Muri Laboratwari yo Gutunganya Amabatiri ya Kaminuza ya Chalmers, itsinda ryagerageje gutunganya ibintu by'umukara, uruvange rw'ifu y'ibikoresho by'ingenzi bikora muri bateri, muri aside oxalic. By'umwihariko, twavugaga kuri bateri y'imodoka ikoresha amashanyarazi ya Volvo. Inyandiko ivuga ko inzira ari "guteka ikawa." Mu by'ukuri, byose biragoye cyane, kuko kugira ngo inzira ya aside oxalic itange umusaruro wifuza, ni ngombwa guhitamo neza ubushyuhe, ingano n'igihe imara. Ariko kandi, aside oxalic iboneka mu bimera nka rhubarb na epinari.
“Kugeza ubu, nta muntu washoboye kubona uburyo bukwiye bwo gutandukanya ingano nini ya lithiyumu hakoreshejwe aside oxalic no gukuraho aluminiyumu yose. Kubera ko bateri zose zirimo aluminiyumu, tugomba kubasha kuyikuraho tudatakaje ibindi byuma,” nk’uko Leah Rouquette, umunyeshuri wa kaminuza mu ishami abisobanura.
Mu mikorere ikoreshwa muri hydrometallurgike, ibintu bya fer bishongeshwa muri aside inorganic. "Imyanda" nka aluminiyumu na umuringa irakurwaho hanyuma ibikoresho bikora nka kobalti, nikeli, manganese na lithiyumu bigasubizwamo.
Ariko, abashakashatsi bo muri Suwede bavuga ko n'ingano nto ya aluminiyumu n'umuringa bisigaye bisaba intambwe nyinshi zo gusukura, kandi buri ntambwe muri icyo gikorwa ishobora gutuma litiyumu itakaza. Bakoresheje uburyo bushya, abashakashatsi bahinduye gahunda maze bagabanya litiyumu na aluminiyumu mbere na mbere. Ibi bituma bagabanya gupfusha ubusa ibyuma by'agaciro bikenewe mu gukora bateri nshya.
Intambwe ikurikiraho ishobora no kugereranywa no guteka ikawa: mu gihe aluminiyumu na lithiyumu biri mu mazi, ibyuma bisigaye biguma mu "bikomeye". Intambwe ikurikiraho muri iki gikorwa ni ugutandukanya aluminiyumu na lithiyumu. "Kubera ko ibi byuma bifite imiterere itandukanye cyane, ntidutekereza ko bizagorana kubitandukanya. Uburyo bwacu ni uburyo bushya bwiza bwo kongera gukoresha bateri, kandi bukwiye gukorerwa ubushakashatsi bwimbitse," Rouquette yagize ati.
“Dukeneye ubundi buryo busimbura imiti idakomoka ku bimera. Imwe mu mbogamizi zikomeye muri iki gihe ni ugukuraho ibikoresho bisigaye nka aluminiyumu. Ubu ni uburyo bushya bushobora gutanga ubundi buryo bushya bwo gucunga imyanda no gufasha gukemura ibibazo bidindiza iterambere,” nk’uko byatangajwe na Porofeseri w’ishami. Martina Petranikova. Icyakora, yongeyeho ko ubu buryo busaba ubushakashatsi bw’inyongera: “Kubera ko ubu buryo bushobora kongerwamo imbaraga, twizeye ko bushobora gukoreshwa mu nganda mu myaka iri imbere.”
Kuva mu 2011, twakomeje gutangaza ibijyanye n'iterambere ry'ibinyabiziga bikoresha amashanyarazi dushishikajwe n'ubuhanga n'itangazamakuru. Nk'itangazamakuru rikomeye ry'inzobere mu ruganda, dutanga amakuru meza kandi yuzuye ku bikorwa, akaba ari urubuga rw'ingenzi rwo guteza imbere ikoranabuhanga vuba. Harimo amakuru, amakuru y'inkomoko, raporo z'ibinyabiziga, ibiganiro, amashusho n'amakuru yo kwamamaza.
