Ma silicon anode akwezva kutariswa kukuru muindasitiri yemabhatiri. Zvichienzaniswa nemabhatiri e lithiamu-ionvachishandisa ma graphite anodes, vanogona kupa huwandu hwakakura ka3-5. Kukura kwesimba kunoreva kuti bhatiri rinogara kwenguva yakareba mushure mekuchaja kwega kwega, izvo zvinogona kuwedzera zvakanyanya daro rekutyaira remotokari dzemagetsi. Kunyangwe silicon yakawanda uye yakachipa, kutenderera kwekuchaja-kuburitsa maSi anodes kwakaganhurirwa. Munguva yega yega yekuchaja-kuburitsa, huwandu hwavo huchawedzerwa zvakanyanya, uye kunyange kugona kwavo kuchaderera, izvo zvinotungamira mukutyoka kwezvikamu zve electrode kana kupatsanurwa kwefirimu re electrode.

Chikwata cheKAIST, chinotungamirwa naPurofesa Jang Wook Choi naPurofesa Ali Coskun, chakashuma musi wa20 Chikunguru kuti pane chinhu chinonamira chemolecular pulley chinonamira mabhatiri e lithium ion ane simba guru ane silicon anodes.

Chikwata cheKAIST chakabatanidza mapuroleji emolecular (anonzi polyrotaxanes) muma electrode binders ebhatiri, kusanganisira kuwedzera ma polymers kuma electrodes ebhatiri kuti asungirire ma electrodes kune substrates dzesimbi. Mhete dziri mu polyrotane dzakasungirirwa mu polymer skeleton uye dzinogona kufamba zvakasununguka pamwe chete ne skeleton.

Mhete dziri mu polyrotane dzinogona kufamba zvakasununguka nekuchinja kwehuwandu hwe silicon particles. Kutsvedza kwemhete kunogona kuchengetedza chimiro che silicon particles zvinobudirira, kuitira kuti dzisaparare mukuchinja kwehuwandu kunoenderera mberi. Zvakakosha kuziva kuti kunyange silicon particles dzakapwanyika dzinogona kuramba dzakafanana nekuda kwekusimba kwakanyanya kwe polyrotane adhesives. Basa re glues idzva rakasiyana zvakanyanya nere glues dziripo (kazhinji ma polymers ari nyore). Adhesives dziripo dzine kusimba kushoma uye nekudaro hadzigone kuchengetedza chimiro che particles zvakasimba. Adhesives dzekare dzinogona kuparadzira zvidimbu zvakapwanyika uye kuderedza kana kutorasikirwa nekugona kwe silicon electrodes.

Munyori anotenda kuti uku kuratidzwa kwakanaka kwekukosha kwekutsvaga kwekutanga. Polyrotaxane yakahwina Mubairo weNobel gore rapera nekuda kwepfungwa ye "makechanical bonds". "Mechanical bonding" ipfungwa itsva inogona kuwedzerwa kumakemikari ekare, akadai se covalent bonds, ionic bonds, coordination bonds uye metal bonds. Tsvagiridzo yenguva refu iri kugadzirisa zvishoma nezvishoma matambudziko enguva refu etekinoroji yebhatiri nekukurumidza kusingatarisirwi. Vanyori vakataurawo kuti parizvino vari kushanda nemugadziri mukuru wemabhatiri kuti vabatanidze mapurole avo emamorekuru muzvigadzirwa zvebhatiri chaizvo.

Sir Fraser Stoddart, akahwina mubairo weNoble Laureate Chemistry Award muna 2006 kuNorthwestern University, akawedzera kuti: “Mabhondi emakanika adzoka kekutanga munzvimbo inochengeterwa simba. Chikwata cheKAIST chakashandisa zvine hunyanzvi mabhindi emakanika mu slip-ring polyrotaxanes uye functionalized alpha-cyclodextrin spiral polyethylene glycol, zvichiratidza kubudirira mukushanda kwemabhatiri e lithium-ion pamusika, apo pulley-shaped aggregates ne mechanical binders. Makomponi anotsiva zvinhu zvemazuva ano ne chemical bond imwe chete, iyo ichava nemhedzisiro yakakura pahunhu hwezvinhu nemidziyo.
