Abashakashatsi bo muri Kaminuza y’Ikoranabuhanga ya Chalmers batanze uburyo bushya kandi bunoze bwo kongera gukoresha ibyuma biva muri bateri z’imodoka zikoresha amashanyarazi. Ubu buryo bugarura aluminiyumu 100% na lithiyumu 98% muri bateri za EV zakoreshejwe. Ibi bigabanya igihombo cy’ibikoresho fatizo by’agaciro nka nikeli, kobalti na manganese. Ubu buryo ntibusaba imiti ihenze cyangwa yangiza kuko abashakashatsi bakoresheje aside oxalike, aside iboneka no mu bwami bw’ibimera.
Kugeza ubu, nta muntu washoboye kubona uburyo bukwiye bwo gutandukanya ingano ya lithiyumu hakoreshejwe aside oxalic no gukuraho aluminiyumu yose. Leah Rouquette, umunyeshuri wa PhD mu ishami rya chimie n'ubuhanga mu by'ubutabire muri kaminuza ya Chalmers y'ikoranabuhanga, yavuze ko kubera ko bateri zose zirimo aluminiyumu, twagombye kubasha kuyikuraho tudatakaje ibindi byuma.
Muri Laboratwari yo Gutunganya Amabatiri muri Kaminuza y’Ikoranabuhanga ya Chalmers, Leah Rouquette n’umuyobozi w’ubushakashatsi Martina Petranikova bagaragaje uburyo ubu buryo bushya bukora. Laboratwari yari irimo bateri z’imodoka zakoreshejwe, kandi mu gipfundikizo cy’umuriro hari ibikoresho byamenetse mu buryo bw’ifu y’umukara ishongeshejwe neza mu mazi asobanutse - aside oxalike. Leah Rouquette akoresha ikintu gisa n’icyuma gikoreshwa mu gikoni mu kuvanga ibinyobwa n’ifu. Nubwo bisa nko koroshye nk’aho arimo gukora ikawa, ubu buryo bwihariye ni umwihariko kandi ni intambwe iherutse gusohoka mu bya siyansi. Binyuze mu kugena neza ubushyuhe, ubwinshi n’igihe, abashakashatsi bakoze resept nshya ikoresha aside oxalike, ikintu kitangiza ibidukikije kiboneka no mu bimera nka rhubarb na epinari.
Hakenewe ubundi buryo bwo guhindura imiti idakomoka ku bimera muri iki gihe. Byongeye kandi, imwe mu mbogamizi zikomeye mu mikorere ya none ni ugukuraho ibisigazwa by'ibikoresho nka aluminiyumu. Martina Petranikova, Porofeseri wungirije mu ishami rya chimie n'ubuhanga mu by'ubutabire muri kaminuza ya Chalmers y'ikoranabuhanga, yavuze ko ari uburyo bushya bushobora gutanga ubundi buryo bushya bwo kongera gukoresha ibikoresho mu nganda zikora ibikoresho byo kongera gukoresha ibikoresho no gufasha gukemura ibibazo bidindiza iterambere.
Uburyo bwo gutunganya hakoreshejwe amazi bwitwa hydrometallurgy. Muri hydrometallurgy isanzwe, "umwanda" uva mu bikoresho nka aluminiyumu n'umuringa ubanza gukurwaho, hanyuma hagakoreshwa ibyuma by'agaciro nka lithiyumu, cobalt, nikeli na manganese. Nubwo hasigaye aluminium nke n'umuringa, hakenewe ibyiciro byinshi byo gusukura, kandi buri cyiciro cy'igikorwa gitera kuva amazi. Muri ubwo buryo bushya, abashakashatsi bahinduye icibwa maze babanza gutandukanya lithiyumu na aluminiyumu. Muri ubu buryo, bashobora kugabanya imyanda y'ibyuma by'agaciro bikenewe mu gukora bateri nshya.
Ndetse n'igice cya kabiri cy'iyi gahunda—kuyungurura uruvange rwijimye—bitwibutsa guteka ikawa. Mu gihe aluminiyumu na lithiyumu byinjira mu mazi, ibindi byuma biguma mu "sump". Intambwe ikurikira muri iyi gahunda ni ugutandukanya aluminiyumu na lithiyumu.
Leah Rouquette agira ati: “Kubera ko ibi byuma bifite imiterere itandukanye cyane, twizera ko kubitandukanya bitazagorana. Uburyo bwacu bushya butanga inzira nshya yizewe yo kongera gukoresha bateri, dufite imbaraga zo kubishakisha cyane.” “Kubera ko ubu buryo bushobora no gukoreshwa ku rugero runini, twizeye ko buzagira akamaro mu nganda mu myaka iri imbere.”
Itsinda ry’ubushakashatsi rya Martina Petranikova rimaze imyaka myinshi rikora ubushakashatsi bukomeye ku bijyanye no kongera gukoresha ibyuma mu bateri za lithiamu-iyoni. Iri tsinda rikorana n’amasosiyete afite uruhare mu kongera gukoresha bateri z’imodoka zikoresha amashanyarazi, kandi ni umufatanyabikorwa mu mishinga minini y’ubushakashatsi n’iterambere nka Volvo Cars n’umushinga wa Northvolt wa Nybat.
Amakuru y'inyongera ku bushakashatsi: Inyandiko ya siyansi igira iti “Gukuramo litiyumu mu bateri z'amashanyarazi za lithiyumu-ion: gukora ibishushanyo no kunoza hakoreshejwe aside oxalic nk'umusemburo” yasohotse mu kinyamakuru Separation and Purification Technology. Ubushakashatsi bwakozwe na Leah Rouquette, Martina Petranikova na Natalia Vieceli bo mu ishami rya chimie n'ubuhanga mu bya chimie muri kaminuza ya Chalmers. Ubushakashatsi bwatewe inkunga n'ikigo gishinzwe ingufu cya Suwede, ikigo cy'amashanyarazi cya Suwede na Vinnova, kandi igerageza ryakozwe hakoreshejwe bateri z'amashanyarazi za Volvo Cars zakoreshejwe zatunganyijwe na Stena Recycling na Akkuser Oy.
