Ƙungiyar binciken kimiyya ta Jami&39;ar Les ta dogara ne akan tef, haɗe da wasu fasaha na Laser na ci gaba, kuma sun haɓaka sabon nau&39;in kayan lantarki. Wannan abu zai iya shawo kan matsalolin dogon lokaci na baturin lithium-ion na yanzu kuma yana tsammanin ƙara aikin baturi. Batirin ƙarfe na Lithium yana nufin baturin da aka saba amfani da shi azaman graphite wanda ake amfani dashi azaman anode (electrodes biyu) zuwa batir lithium ɗin ƙarfe zalla.

Tun da wannan kayan yana da ƙarfin ƙarfin ƙarfi sosai, ƙarfe lithium na iya sa saurin cajin baturi ya haɓaka sosai, kuma ƙarfin yana iya kaiwa sau 10. Duk da haka, har yanzu akwai wasu gazawa a cikin batir lithium-ion, wanda ya fi damuwa ga "dendrites". A lokacin caji, waɗannan dendrites an kafa su a saman anode kuma suna iya haifar da gajeren kewayawa, gazawa ko wuta, don haka an tattara adadi mai yawa na nazarin baturi don kashe su.

Ƙungiyar binciken kimiyya daga Jami&39;ar Les tana da sabon ɓarna a cikin wannan rukuni, na farko shine tef. Tawagar ta ba da tef ɗin zuwa ga mai karɓar jan ƙarfe na yanzu wanda ya ƙunshi lithium anode, kuma an warware shi da laser don dumama shi zuwa matsanancin zafin jiki na 2300 Kelvin (3680 ¡ã F ko 2026 ¡ã C), ta haka yana ba da wasu fa&39;ida sosai. Sabon fasali.

Wannan tsari yana juya tef ɗin zuwa sutura mai laushi, wanda yake da kyawawa don tsarawa daga silicon, oxygen, da ƙananan graphene mai ban mamaki. Don gwajin farko na fim ɗin, ana iya amfani da shi azaman kariya mai kariya na taron masu tarawa na yanzu, wanda zai iya sha kuma ya saki lithium na ƙarfe, kuma ba zai haifar da dendrites masu cutarwa ba. A cikin rufin kariyar silicon oxide da ke haifar da Laser, ƙungiyar Ƙananan Jami&39;ar na iya samun hanyar yin amfani da waɗannan kyawawan abubuwan, ba sabon nauyin nauyin lithium ba.

Bayanin gwajin sa, baturin sanye take da sabon rufin sa ya nuna sau uku rayuwar sauran batir lithium-ion karfe na "sifili", kuma yana da karfin 70% a cikin zagayowar caji 60. Ƙungiyar ta yi nazarin cewa wannan fasaha tana da sauri kuma mai aminci, ba ta haɗa da sauran ƙarfi ba, kuma za&39;a iya yin shi a cikin zafin jiki. Sabili da haka, an aika shi zuwa bege kuma ya yi imanin yana da babban iko mai girma.
