Iterambere mu ikoranabuhanga ryo kongera gukoresha bateri za Lithium-Ion

Ubushakashatsi buherutse gusohoka ku ya 29 Nyakanga mu kinyamakuruIbikoresho by'ingirakamaro bigezwehoisobanura uburyo bwihuse, bwiza, kandi butangiza ibidukikije bwo kugarura lithium hifashishijwe imirasire ya microwave hamwe n'umusemburo woroshye kubora. Abashakashatsi bo muri Kaminuza ya Rice muri Leta Zunze Ubumwe za Amerika bateguye ubu buryo bushya, bushobora kugarura 50% bya lithium bivuye muri bateri ya lithium-ion yakoreshejwe (LIB) mu masegonda 30 gusa, bigakemura ikibazo gikomeye mu ikoranabuhanga ryo kongera gukoresha LIB.

Muri iki gihe, igikenewe cya lithium, icyuma cy’umweru nk’ifeza, kirimo kwiyongera cyane kurusha ingano y’ibicuruzwa bitangwa.

Uburyo gakondo bwo kugarura lithium muri batiri zakoreshejwe burangiza ibidukikije kandi ntibukora neza cyane. Ingorane nyamukuru zirimo kwanduza lithium no gutakaza igihe cyo kugarura, hamwe no gukoresha ingufu nyinshi. Kubera ko lithium ikunze gukurwamo nyuma y’ibindi byuma, abashakashatsi bashatse uburyo bwihariye bwo kugarura lithium.

Muri ubu bushakashatsi, abashakashatsi bakoresheje uruvange rwa choline chloride na ethylene glycol nk'umusemburo wimbitse wa eutectic (DES). Mbere bavumbuye ko mu gihe cyo gusohora DES, iyoni za lithium zizengurutswe na iyoni za chloride zivuye kuri choline chloride hanyuma zigashyirwa mu gisubizo.

Kugira ngo havemo ibindi byuma nka cobalt cyangwa nikeli, hakenewe choline chloride na ethylene glycol. Muri ibyo bintu, choline chloride ni yo yonyine ifata mikorobe neza. Abashakashatsi binjije imyanda ya bateri mu cyuma gishongesha ibintu maze bashyiramo imirasire ya mikorobe, bituma litiyumu iva mu bindi byuma ivamo.

Gukoresha imirasire ya mikoroonde muri ubu buryo bisa no gushyushya ibiryo vuba mu itanura rya mikoroonde ryo mu gikoni. Ingufu zishyirwa mu buryo butaziguye mu matsinda, bigatuma ingaruka zihuta cyane kurusha uburyo busanzwe bwo gushyushya.

Abashakashatsi basanze uburyo bwo gukoresha mikoroonde, gukuramo 87% bya lithiyumu byatwaraga iminota 15, mu gihe kugera ku gipimo kimwe cyo kugarura ubushyuhe hakoreshejwe amavuta yo mu bwogero byatwaraga amasaha 12. Ubu buryo bushya butuma habaho iterambere rikomeye mu bukungu no mu ngaruka ku bidukikije zo kongera gukoresha bateri za lithiyumu-iyoni, butanga igisubizo gishya kirambye ku kibazo cy’isi kirimo kwiyongera.
