Abashakashatsi bavumbuye uburyo bwo kongera gukoresha ibikoresho bishobora kugarura 100% bya aluminiyumu na 98% bya lithiyumu iri muri batiri z'imodoka zikoresha amashanyarazi.
Abashakashatsi bo muri Suwede bavuga ko bateguye uburyo bushya kandi bunoze bwo kongera gukoresha bateri z'imodoka zikoresha amashanyarazi.
“Kubera ko ubu buryo bushobora kongerwa, twizeye ko buzakoreshwa mu nganda mu myaka iri imbere,” uyu ni Martina Petranikova, umuyobozi w’ubushakashatsi.
Mu buhanga busanzwe bwo gukoresha amashanyarazi, ibyuma byose biri mu mabati y'imodoka zikoresha amashanyarazi bishongeshwa muri aside inorganic.
"Imyanda" nka aluminiyumu n'umuringa irakurwaho hanyuma hakaboneka ibyuma by'agaciro nka kobalti, nikeli, manganese na lithiyumu.
Nubwo ingano ya aluminiyumu n'umuringa bisigaye ari bike, bisaba intambwe nyinshi zo gusukura, kandi buri ntambwe muri icyo gikorwa ishobora gutuma litiyumu itakaza.
Abashakashatsi bo muri Kaminuza y’ikoranabuhanga ya Chalmers yo muri Suwede bakoze uburyo bwo kongera gukoresha ibikoresho bishobora kugarura 100% bya aluminiyumu na 98% bya lithiyumu mu bateri z’imodoka zikoresha amashanyarazi.
Bikubiyemo guhindura urukurikirane rw'imikorere igezweho no gutunganya cyane cyane lithiyumu na aluminiyumu.
Muri icyo gihe, igihombo cy'ibikoresho fatizo by'agaciro nka nikeli, kobalti na manganese kiragabanuka.
“Kugeza ubu, nta muntu washoboye kubona uburyo bukwiye bwo gukoresha aside oxalic mu gutandukanya ingano nini ya lithium mu gihe akuramo aluminiyumu yose icyarimwe,” ibi ni ibyatangajwe na Leah Rouquette, umunyeshuri warangije mu ishami rya chimie n’ubuhanga mu by’ubutabire muri kaminuza ya Chalmers.
“Kubera ko bateri zose zirimo aluminiyumu, tugomba kubasha kuzikuraho tudatakaje izindi metali.”
Mu cyumba cyabo cyo gusuzuma bateri, Rouquette n'umuyobozi w'ubushakashatsi Petranikova bashyize bateri z'imodoka zakoreshejwe n'ibirimo byazimenetse mu gipfundikizo cy'umuriro.
Ifu y'umukara isya neza ishongeshwa mu mazi y'umwimerere yitwa aside oxalic, ikintu kibisi kiboneka mu bimera nka rhubarb na epinari.
Shyira ifu n'amazi mu mashini isa n'icyuma gikoresha imashini yo mu gikoni. Aha ngaha, aluminiyumu na lithiyumu biri muri batiri bishongeshwa muri aside oxalike, ibyuma bisigaye bisigara mu buryo bukomeye.
Intambwe ya nyuma muri iki gikorwa ni ugutandukanya ibi byuma kugira ngo hakorwe lithiyumu, hanyuma igakoreshwa mu gukora bateri nshya.
Rouquette yagize ati: “Kubera ko ibi byuma bifite imiterere itandukanye cyane, ntidutekereza ko bizagorana kubitandukanya. Uburyo bwacu ni uburyo bushya bwiza bwo kongera gukoresha bateri, kandi bukwiye gusuzumwa neza.”
Itsinda ry’abashakashatsi rya Petranikova ryamaze imyaka myinshi rikora ubushakashatsi bugezweho ku bijyanye no kongera gukoresha ibyuma mu bateri za lithiamu-iyoni.
Akorana n'ibigo bitandukanye bikora mu kongera gukoresha bateri z'imodoka zikoresha amashanyarazi. Iri tsinda ni umufatanyabikorwa mu mishinga minini y'ubushakashatsi n'iterambere, kandi ibirango byaryo birimo Volvo na Northvolt.
