Iqela lophando lwenzululwazi yeYunivesithi yaseLes isekelwe kwiteyiphu, idityaniswe nobuchwepheshe belaser obuphambili, kwaye iphuhlise uhlobo olutsha lwezinto ze-electrode. Esi sixhobo sinokunqoba iingxaki zexesha elide zebhetri ye-lithium-ion yangoku kwaye ulindele ukwandisa ukusebenza kwebhetri. Ibhetri yentsimbi yelithium ibhekisa kwibhetri esetyenziswa ngokuqhelekileyo njengegraphite esetyenziswa njenge-anode (i-electrode ezimbini) kwibhetri yentsimbi ecocekileyo ye-lithium.
Ekubeni le nto inamandla aphezulu kakhulu, i-lithium yensimbi inokwenza isantya sokutshaja kwebhetri sikhawuleze kakhulu, kwaye umthamo unokufikelela kumaxesha angama-10. Nangona kunjalo, kusekho ukusilela kwiibhetri ze-lithium-ion, eyona ngxaki "i-dendrites". Ngethuba lenkqubo yokutshaja, ezi dendrites zenziwe kumphezulu we-anode kwaye zingabangela isiphaluka esifutshane, ukungaphumeleli okanye umlilo, ngoko ke inani elikhulu lezifundo zebhetri zigxininiswe.
Iqela lophando lwezenzululwazi kwiYunivesithi yaseLes inenkqubela entsha kulo mmandla, okokuqala yiteyiphu. Iqela lidlulisela i-tape kumqokeleli wangoku wobhedu owenza i-lithium anode kwaye uyiphathe nge-laser ukuyifudumeza kubushushu obugqithisileyo be-2300 Kelvin (3680 ¡ã F okanye i-2026 ¡ã C), ngaloo ndlela inika into entsha eluncedo kakhulu. Le nkqubo ijika i-tape ibe yi-coating ene-porous, ebaluleke kakhulu kwi-silicon, i-oksijeni, kunye nenani elincinci le-graphene yezinto zomlingo.
Uvavanyo lwangaphambili kwifilimu lubonisa ukuba lunokusetyenziswa njengoluhlu olukhuselayo lweendibano zangoku zabaqokeleli, ezinokufunxa kwaye zikhulule i-lithium yensimbi, kwaye ayiyi kuvumela i-dendrites eyingozi. Kwi-laser-induced silicon oxide yokukhusela i-coating, iqela leYunivesithi eNcinci linokuthi lifumene indlela yokusebenzisa le miba emihle, kungekhona esanda kwandisa umthwalo we-lithium. Imifuniselo yayo ibonisa ukuba ibhetri kunye nokugquma kwayo okutsha kubonisa ngokuphindwe kathathu ubomi bezinye iibhetri ze-lithium-ion zesinyithi, kwaye igcina umthamo we-70% kwimijikelo yentlawulo engama-60.
Iqela lazisa ukuba le teknoloji ikhawuleza kwaye ikhuselekile, ayibandakanyi i-solvent, kwaye inokuqhutyelwa kwiqondo lokushisa. Ke ngoko, lithemba kakhulu, licinga ukuba linamandla okwandisa isikali.
