Batura lithium sun canza na’urorin lantarki ta hannu kuma ana amfani da su a cikin sabbin na’urorin makamashi, amma ƙarin haɓakawa a rayuwa da ƙarfi zai buƙaci sabbin fasahohi. Ɗayan zaɓi shine baturan ƙarfe na lithium, waɗanda ke da tsawon rayuwar baturi da saurin caji, amma akwai matsalolin wannan fasaha. Lithium adibas, da ake kira dendrites, sukan girma a kan anode kuma zai iya samar da wani gajeren kewaye, haifar da gazawar baturi, wuta ko fashewa.

A halin yanzu, masu bincike daga kwalejin ilmin sinadarai, da kwalejin kimiyyar kasar Sin, da jami’ar koyon ilmin kimiyya ta kasar Sin, da cibiyar binciken kimiyya da fasaha mai zurfi ta kasar Sin, sun kera wani na’ura mai rabe-rabe ta hanyar yin amfani da sinadarin carbon allotropes. Ana kiran shi graphene, wanda ke aiki azaman tace lithium ion don hana ci gaban dendritic [Shangetal. Material.10 (2018) 191-199].

Batura na ƙarfe na lithium suna kama da ra’ayi da baturan lithium, amma sun dogara da anodes na ƙarfe na lithium. A lokacin aikin fitarwa, lithium anode yana samar da electrons zuwa cathode ta hanyar da’ira ta waje. Koyaya, lokacin caji, ana ajiye lithium akan anode. A cikin wannan tsari, dendrites maras so zai haifar.

Wannan shine aikin diaphragm. Mai raba membrane da aka yi da ultra-bakin ciki (10nm) graphite diacetylene (mai girma biyu hexagonal carbon atom monolayer wanda aka haɗa ta sarƙoƙin succinic acid) yana da mahimmancin ƙima. Graphite diacetylene ba wai kawai yana da elasticity da tauri ba, amma tsarinsa na sinadari kuma yana samar da hanyar sadarwa ta pore iri ɗaya, yana barin lithium ion guda ɗaya kawai ya wuce. Wannan yana daidaita motsin ions ta cikin membrane, yana haifar da yaduwar ions daidai gwargwado. Mahimmanci, wannan sifa ta yadda ya kamata ya hana ci gaban lithium dendrites.

Li Yuliang na kwalejin nazarin ilmin sinadarai ta kwalejin kimiyyar kasar Sin, wanda ya jagoranci binciken, ya bayyana cewa, lithium dendrites na iya daidaita ma’aunin karfin wutar lantarki, ta yadda za a tsawaita tsawon rayuwar na’urar da wutar lantarki ta Coulomb. Hana gajeriyar da’ira mai siffar bishiya kuma isa ga baturi lafiya.

Masu bincike sun yi imanin cewa fina-finan graphene-diethyne za su iya shawo kan wasu matsalolin ƙaya da batirin lithium da sauran baturan ƙarfe na alkaline ke fuskanta.

Li ya ce graphitic diacetylene abu ne mai haɓakawa tare da tsari mai haɗaɗɗiya, gibin bandeji na asali, tsarin macroporous na halitta da aikin semiconductor. Yana ba da kyakkyawar fata don magance manyan matsalolin kimiyya a wannan fagen.

Bayanai masu girma biyu kuma suna da sauƙin gaske, kuma yana da sauƙin samuwa a ƙarƙashin yanayin dakin gwaje-gwaje na gabaɗaya.

Masu binciken sun shaida wa manema labarai cewa, ko da yake akwai bukatar a kara yin aiki don inganta ingancin fina-finan graphite-diacetylene a babban sikelin, mun yi imanin cewa graphite-diacetylene na iya yin tasiri sosai kan amincin batirin lithium.
