Silicon anode yakwegereye cyane mubikorwa bya batiri.Ugereranije nabateri ya lithium-ionukoresheje grafite anode, zirashobora gutanga ubushobozi bunini inshuro 3-5.Ubushobozi bunini bivuze ko bateri izaramba nyuma ya buri giciro, gishobora kwagura cyane intera yo gutwara ibinyabiziga byamashanyarazi.Nubwo silikoni ari myinshi kandi ihendutse, inzinguzingo-isohoka ya Si anode ni nto.Muri buri cyiciro cyo kwishyuza-gusohora, ingano yabyo izaguka cyane, ndetse nubushobozi bwabo buzagabanuka, ibyo bikaviramo kuvunika ibice bya electrode cyangwa gusenya firime ya electrode.

Itsinda rya KAIST riyobowe na Porofeseri Jang Wook Choi na Porofeseri Ali Coskun, ryatangaje ku ya 20 Nyakanga ko umusemburo wa molekuline ufata bateri nini ya litiro ion zifite ubushobozi bwa anode ya silicon.

Itsinda rya KAIST ryinjije molekile pulleys (bita polyrotaxane) mumashanyarazi ya bateri ya electrode, harimo kongeramo polymers kuri electrode ya batiri kugirango ihuze electrode na substrate yicyuma.Impeta ziri muri polyrotane zinjijwe muri polymer skeleton kandi irashobora kugenda yisanzuye kuri skeleton.

Impeta ziri muri polyrotane zirashobora kugenda mubwisanzure hamwe nihinduka ryijwi ryibice bya silicon.Kunyerera kw'impeta birashobora kugumana neza imiterere yibice bya silicon, kugirango bitazasenyuka muburyo bukomeza bwo guhindura amajwi.Birashimishije kubona ko uduce duto twa silicon twajanjaguwe dushobora gukomeza guhurira hamwe kubera ubwinshi bwimikorere ya polyrotane.Imikorere yibikoresho bishya bitandukanye cyane cyane nibisanzweho (mubisanzwe byoroshye umurongo wa polymers).Ibifatika bihari bifite ubuhanga buke bityo ntibishobora gukomeza imiterere yimiterere.Ibikoresho byabanje birashobora gusasa ibice byajanjaguwe kandi bikagabanya cyangwa bigatakaza ubushobozi bwa electrode ya silicon.

Umwanditsi yizera ko iki ari ikimenyetso cyiza cyerekana akamaro k'ubushakashatsi bwibanze.Polyrotaxane yatsindiye igihembo cyitiriwe Nobel umwaka ushize kubera igitekerezo cy '“imashini zikoreshwa”."Mechanical bonding" nigitekerezo gishya cyasobanuwe gishobora kongerwa kumasoko ya chimique ya kera, nka covalent bonds, ionic bonds, guhuza imiyoboro hamwe nicyuma.Ubushakashatsi bwigihe kirekire burimo gukemura buhoro buhoro ibibazo bimaze igihe kinini byikoranabuhanga rya batiri ku kigero gitunguranye.Abanditsi bavuze kandi ko kuri ubu barimo gukorana n’uruganda runini rwa batiri kugira ngo bahuze molekile zabo mu bicuruzwa nyabyo.

Sir Fraser Stoddart, 2006 wegukanye igihembo cya Noble Laureate Chemistry Award muri kaminuza ya Northwestern, yongeyeho ati: “Imashini zikoresha imashini zongeye kugaruka ku nshuro ya mbere mu bubiko bw'ingufu.Ikipe ya KAIST yakoresheje ubuhanga bwo guhuza imashini muri polyrotaxane kunyerera kandi ikora alpha-cyclodextrin spiral polyethylene glycol ikora, ibyo bikaba byerekana ko hari intambwe imaze guterwa mu mikorere ya bateri ya lithium-ion ku isoko, iyo igiteranyo kimeze nka pulley hamwe na mashini zihuza imashini.Imvange isimbuza ibikoresho bisanzwe hamwe nubumwe bumwe gusa, bizagira ingaruka zikomeye kumiterere yibikoresho nibikoresho.
