Tekinike yo kuyobora iterambere ryihuta kandi riramba rya bateri-yigihe kizaza

Tekinoroji isukuye kandi ikora neza ningirakamaro mugushiraho ibikorwa remezo byingufu zishobora kubaho.Batteri ya Litiyumu-ion isanzwe yiganje mubikoresho bya elegitoroniki, kandi isezeranya abakandida kububiko bwizewe bwo murwego rwa gride hamwe nibinyabiziga byamashanyarazi.Ariko, iterambere rirakenewe kugirango tunonosore igipimo cyamafaranga nigihe cyo gukoresha.

Kugira ngo bafashe iterambere rya bateri zihuta kandi zimara igihe kirekire, abahanga bakeneye kumenya inzira zibera imbere muri bateri ikora, kugirango bamenye aho ubushobozi bwa bateri bugarukira.Kugeza ubu, kwiyumvisha ibikoresho bya batiri bikora nkuko bikora bisaba syncrotron X-ray cyangwa tekinoroji ya microscopi ya elegitoronike, ishobora kugorana kandi ihenze, kandi akenshi ntishobora gushushanya byihuse kugirango ifate impinduka zihuse ziboneka mubikoresho bya electrode byihuta.Nkigisubizo, ion dinamike ku burebure-burebure bwibice bikora kandi no mubucuruzi bujyanye nubucuruzi bwihuse-bwishyurwa bikomeza kuba ubushakashatsi.

Abashakashatsi bo muri kaminuza ya Cambridge batsinze iki kibazo batezimbere tekinike ihendutse ya laboratoire ishingiye kuri optique ya microscopi optique yo kwiga bateri ya lithium-ion.Basuzumye ibice bya Nb14W3O44, biri mubikoresho byihuta byishyurwa anode kugeza ubu.Umucyo ugaragara woherejwe muri bateri unyuze mu idirishya rito ry'ikirahure, bituma abashakashatsi bareba inzira igenda ikora mubice bikora, mugihe nyacyo, mubihe bitarimo uburinganire.Ibi byagaragaje imbere-nka lithium-concentration gradients zinyura mubice byihariye bikora, bikaviramo imbaraga zimbere zatumye ibice bimwe bivunika.Kuvunika ibice ni ikibazo kuri bateri, kubera ko gishobora gutuma amashanyarazi ahagarara ibice, bikagabanya ubushobozi bwo kubika bateri.Umwanditsi umwe, Dr Christoph Schnedermann, ukomoka muri Laboratwari ya Cavendish ya Cambridge, agira ati: “Ibintu nk'ibyo bidatunguranye bigira ingaruka zikomeye kuri batiri, ariko ntibishobora kugaragara mu gihe nyacyo mbere ya none.”

Ubushobozi bwinshi-bwinjiza bwa tekinike ya optique ya microscopi yafashije abashakashatsi gusesengura umubare munini wibice, byerekana ko gucamo ibice bikunze kugaragara hamwe nigipimo kinini cyo gutandukana no mubice birebire.Umwanditsi wa mbere, Alice Merryweather, umukandida wa PhD mu ishami rya Laboratwari ya Cavendish ya Cambridge, yagize ati:

Kujya imbere, ibyiza byingenzi byuburyo bukoreshwa - harimo kubona amakuru yihuse, kubona igisubizo kimwe, hamwe nubushobozi bwinshi bwo kwinjiza - bizafasha kurushaho gushakisha uko bigenda iyo bateri zananiwe nuburyo bwo kuyirinda.Tekinike irashobora gukoreshwa mukwiga hafi ubwoko bwibikoresho bya bateri, bikabigira igice cyingenzi cya puzzle mugutezimbere bateri izakurikiraho.
