Abashakashatsi barateguye uburyo bwo gusubira gukoresha ibintu bishobora gusubira gukoresha 100% vy’aluminium n’ibice 98% vy’ivyuma vy’umuyagankuba biri mu mabati y’ibinyabiziga bikoresha umuyagankuba.
Abashakashatsi bo muri Suède bavuga ko bateguye uburyo bushasha kandi bukora neza cane bwo gusubira gukoresha amabateri y’ibinyabiziga bikoresha umuyagankuba.
Martina Petranikova, uwurongoye iyo nyigisho, yavuze ati: “Kubera ko ubwo buryo bushobora gukoreshwa cane, twizigiye ko buzokoreshwa mu nganda mu myaka iri imbere.”
Mu buhinga bwa kera bwo gukora ivyuma mu mazi, ivyuma vyose biri mu mabati y’ibinyabiziga bikoresha umuyagankuba biva mu ma aside atagira ubuzima.
”Ibihumanye” nk’ivy’aluminiyumu n’ivy’umuringa biraheza bikakurwaho, ivyuma vy’agaciro nka cobalt, nickel, manganese na litiyumu bikagaruka.
Naho umubare w’amasigarira y’aluminiyumu n’umuringa ari muto, bisaba intambwe nyinshi zo gusukura, kandi intambwe yose yo gusukura ishobora gutuma umuntu atakaza litiyumu.
Abashakashatsi bo muri kaminuza y’ubuhinga bwa none yitwa Chalmers muri Suède, barateguye uburyo bwo gusubira gukoresha ibintu bishobora gusubira gukoresha 100% vy’aluminium n’ibice 98% vy’ivyuma vy’umuyagankuba biri mu mabateri y’imodoka zikoresha umuyagankuba.
Birimwo guhindura urutonde rw’ibikorwa biriho ubu no gutunganya cane cane litiyumu n’aluminiyumu.
Muri ico gihe nyene, ugutakaza ibikoresho vy’agaciro nk’ivy’agaciro bita nickel, cobalt na manganese biragabanywa.
Leah Rouquette, umunyeshure w’umuhinga mu vy’ubuhinga bwa shimi n’ubuhinga bwa shimi, yavuze ati: “Gushika ubu, nta n’umwe yashoboye kuronka ibintu vyiza vyo gukoresha aside oxalique kugira ngo atandukanye litiyumu nyinshi gutyo, mu gihe akuraho aluminium yose icarimwe.” muri kaminuza y’ubuhinga ya Chalmers.
“Kubera ko amabateri yose arimwo aluminium, turakeneye kumenya kuyikuraho tutatakaje ibindi vyuma.”
Mu kibanza cabo co gusubira gukoresha amabateri, Rouquette n’umurongozi w’ubushakashatsi Petranikova barashize amabateri y’imodoka yakoreshejwe be n’ivyo yari arimwo vyajanjaguritse mu gipfukisho c’umwotsi.
Ifu yirabura iseye neza cane ivangwa mu mazi agaragara neza yitwa oxalic acid, kikaba ari ikirungo c’icatsi kibisi kiboneka mu bimera nk’ivyatsi vy’umukara n’ivyatsi vy’umukara.
Ifu n’amazi ubishire mu mashini isa n’iyo mu gikoni. Aha, aluminium na litiyumu biri muri bateri birasenyuka muri aside oxalique, bigatuma ivyuma bisigaye biguma bikomeye.
Intambwe ya nyuma muri iyo nzira ni ugutandukanya ivyo vyuma kugira ngo bikuremwo litiyumu, ivyo bikaba bishobora gukoreshwa mu gukora amabateri mashasha.
Rouquette ati: "Kubera ko ivyo vyuma bifise imiterere itandukanye cane, ntitwibaza ko bizoba bigoye kubitandukanya.
Ishirahamwe ry’abashakashatsi rya Petranikova ryamaze imyaka rikora ubushakashatsi buhambaye ku bijanye no gusubira gukoresha ivyuma mu mabati y’ivyuma bita litiyumu.
Aragira uruhara mu migambi itandukanye yo gukorana n’amashirahamwe akora ibikorwa vyo gusubira gukoresha amabateri y’ibinyabiziga bikoresha umuyagankuba. Iryo shirahamwe ni umufatanyabikorwa mu migambi ikomeye y’ubushakashatsi n’iterambere kandi mu bimenyetso vyaryo harimwo Volvo na Northvolt.
