Ma silicon anode akope chidwi chachikulu m'makampani opanga mabatire. Poyerekeza ndimabatire a lithiamu-ionPogwiritsa ntchito ma anode a graphite, amatha kupereka mphamvu yokulirapo katatu kapena kasanu. Mphamvu yokulirapo imatanthauza kuti batire idzakhala nthawi yayitali pambuyo pa chaji iliyonse, zomwe zitha kukulitsa mtunda woyendetsa magalimoto amagetsi. Ngakhale kuti silicon ndi yochuluka komanso yotsika mtengo, ma cycle a chaji-discharge a ma anode a Si ndi ochepa. Pa nthawi iliyonse ya chaji-discharge, voliyumu yawo idzakulitsidwa kwambiri, ndipo ngakhale capacitance yawo idzachepa, zomwe zingayambitse kusweka kwa tinthu ta electrode kapena kufalikira kwa filimu ya electrode.

Gulu la KAIST, lotsogozedwa ndi Pulofesa Jang Wook Choi ndi Pulofesa Ali Coskun, linanena pa 20 Julayi za gulu la mamolekyulu a pulley a mabatire akuluakulu a lithiamu ion okhala ndi ma silicon anode.

Gulu la KAIST linaphatikiza ma pulley a mamolekyu (otchedwa polyrotaxanes) m'ma batire electrode binders, kuphatikizapo kuwonjezera ma polima ku ma batire electrodes kuti amangirire ma electrodes ku zitsulo. Mphete za polyrotane zimakulungidwa mu polymer skeleton ndipo zimatha kuyenda momasuka m'mabatire.

Mphete za polyrotane zimatha kuyenda momasuka ndi kusintha kwa voliyumu ya tinthu ta silicon. Kutsetsereka kwa mphete kumatha kusunga mawonekedwe a tinthu ta silicon, kuti tisasweke mu njira yopitilira yosinthira voliyumu. Ndikofunikira kudziwa kuti ngakhale tinthu ta silicon tophwanyika titha kukhalabe ndi coalescent chifukwa cha kulimba kwa ma polyrotane. Ntchito ya ma glue atsopano ndi yosiyana kwambiri ndi ya ma glue omwe alipo (nthawi zambiri ma polima osavuta). Ma glue omwe alipo ali ndi kulimba kochepa ndipo motero sangathe kusunga mawonekedwe a tinthu. Ma glue akale amatha kufalitsa tinthu ta silicon ndikuchepetsa kapena kutaya mphamvu ya ma electrode a silicon.

Wolembayo akukhulupirira kuti ichi ndi chisonyezero chabwino kwambiri cha kufunika kwa kafukufuku woyambira. Polyrotaxane adapambana Mphoto ya Nobel chaka chatha chifukwa cha lingaliro la "ma bond a mechanical". "Mechanical bond" ndi lingaliro latsopano lomwe lingawonjezedwe ku ma bond akale a mankhwala, monga ma covalent bond, ma ionic bond, ma coordination bond ndi ma metal bond. Kafukufuku woyambira wa nthawi yayitali akuyang'ana pang'onopang'ono mavuto akale a ukadaulo wa batri pamlingo wosayembekezereka. Olembawo adanenanso kuti pakadali pano akugwira ntchito ndi wopanga mabatire akuluakulu kuti aphatikize ma pulley awo a molecular muzinthu zenizeni za batri.

Sir Fraser Stoddart, wopambana mphoto ya Noble Laureate Chemistry Award mu 2006 ku Northwestern University, anawonjezera kuti: “Ma bond a makina abwerera kwa nthawi yoyamba m'malo osungira mphamvu. Gulu la KAIST linagwiritsa ntchito mwaluso ma bond a makina mu ma polyrotaxanes opindika ndi ma alpha-cyclodextrin spiral polyethylene glycol, zomwe zikusonyeza kupita patsogolo kwa magwiridwe antchito a mabatire a lithiamu-ion pamsika, pamene ma pulley ooneka ngati ma bond amakina amasonkhana pamodzi. Ma compounds amalowa m'malo mwa zinthu wamba ndi bond imodzi yokha ya mankhwala, yomwe idzakhala ndi zotsatira zazikulu pa katundu wa zipangizo ndi zida.
