Anode za silicon zakunzwe cyane mu nganda zikora bateri. Ugereranyije nabateri za lithiamu-iyonihakoreshejwe anode za grafiti, zishobora gutanga ubushobozi bunini inshuro 3-5. Ubushobozi bwinshi busobanura ko batiri izamara igihe kirekire nyuma ya buri gusharija, bishobora kongera cyane intera y'imodoka zikoresha amashanyarazi. Nubwo silikoni ari nyinshi kandi ihendutse, imikorere ya anode za Si ni mike. Muri buri sharija-sharija, ingano yazo izaguka cyane, ndetse n'ubushobozi bwazo buzagabanuka, bizatuma uduce twa electrode ducika cyangwa icyuma cya electrode kigacika.

Itsinda rya KAIST, riyobowe na Porofeseri Jang Wook Choi na Porofeseri Ali Coskun, ryatangaje ku ya 20 Nyakanga kole ya molekile ikoreshwa mu gufunga bateri nini za lithium ion zifite silicon anodes.

Itsinda rya KAIST ryashyize hamwe udupira twa molekile (twitwa polyrotaxanes) mu bikoresho bihuza bateri, harimo no kongeramo polymers kuri bateri kugira ngo bafatanye na electrodes ku byuma. Impeta za polyrotane zishyirwa mu gitereko cya polymer kandi zishobora kugenda neza ku gitereko.

Impeta zo muri polyrotane zishobora kugenda neza iyo uduce twa silikoni duhindutse. Gutembera kw'impeta bishobora kugumana imiterere y'uduce twa silikoni, ku buryo tutazasenyuka mu gihe cyo guhindura ingano. Ni ngombwa kumenya ko n'uduce twa silikoni twasenyutse dushobora kugumana imiterere y'amabara bitewe n'ubukonje bwinshi bwa kole za polyrotane. Imikorere y'uduce dushya itandukanye cyane n'iy'uduce dusanzwe (ubusanzwe ni polymeri zoroshye). Uduce dusanzwe dufite ubukonje buke bityo ntidushobora kugumana imiterere y'uduce. Uduce twa mbere dushobora gukwirakwiza uduce twasenyutse no kugabanya cyangwa gutakaza ubushobozi bwa electrode za silikoni.

Umwanditsi yizera ko iki ari ikimenyetso cyiza cy'ingenzi cy'ubushakashatsi bw'ibanze. Polyrotaxane yegukanye igihembo cya Nobel umwaka ushize kubera igitekerezo cya "imigozi y'imashini". "Imigozi y'imashini" ni igitekerezo gishya gishobora kongerwa ku migozi ya kera ya shimi, nk'imigozi y'imashini, imigozi y'imashini, imigozi yo guhuza hamwe n'imigozi y'icyuma. Ubushakashatsi bw'ibanze bw'igihe kirekire burimo gukemura buhoro buhoro ibibazo bimaze igihe kinini by'ikoranabuhanga rya bateri ku muvuduko utunguranye. Abanditsi banavuze ko ubu barimo gukorana n'uruganda runini rwa bateri kugira ngo bahuze imigozi yabo ya molekile mu bicuruzwa nyabyo bya bateri.

Sir Fraser Stoddart, watsindiye igihembo cya Noble Laureate Chemistry mu 2006 muri Kaminuza ya Northwestern, yongeyeho ati: “Impapuro z’ingufu za mekanike zagarutse bwa mbere mu bubiko bw’ingufu. Itsinda rya KAIST ryakoresheje ubuhanga mu byuma bifunga muri polyrotaxanes zikozwe muri slip-ring na alpha-cyclodextrin spiral polyethylene glycol, bigaragaza iterambere mu mikorere ya bateri za lithium-ion ku isoko, iyo imiterere y’ingufu ihujwe n’impapuro zifunga. Imbuto zisimbura ibikoresho bisanzwe n’impapuro z’ingufu imwe gusa, bizagira ingaruka zikomeye ku miterere y’ibikoresho n’ibikoresho.
