Batrị lithium agbanweela ngwaọrụ eletrọnịkị mkpanaka ma jiri ya na ngwaọrụ ume ọhụrụ, mana n’ihu na nkwalite ndụ na ike ga-achọ teknụzụ ọhụrụ. Otu nhọrọ bụ batrị metal lithium, nke nwere ogologo ndụ batrị yana ọsọ ọsọ ọsọ, mana enwere nsogbu na teknụzụ a. Nkwụnye ego lithium, nke a na-akpọ dendrites, na-etolite na anode ma nwee ike ịmepụta obere sekit, na-akpata ọdịda batrị, ọkụ ma ọ bụ mgbawa.

Ka ọ dị ugbu a, ndị na-eme nchọpụta si na Institute of Chemistry, Chinese Academy of Sciences, University of Chinese Academy of Sciences, na China High Pressure Science and Technology Research Center emebela ihe nkesa akpụkpọ ahụ dabere na carbon allotropes. A na-akpọ ya graphene, nke na-eme dị ka ihe nzacha lithium ion iji gbochie uto dendritic [Shangetal. Ihe.10(2018) 191-199].

Batrị metal lithium yiri n’echiche na batrị lithium, mana dabere na anodes metal lithium. N’oge usoro mwepụ, lithium anode na-enye electrons na cathode site na sekit mpụga. Agbanyeghị, mgbe ị na-ebugharị, a na-edobe lithium na anode. Na usoro a, dendrites achọghị ga-etolite.

Nke a bụ ọrụ nke diaphragm. Ihe nkesa akpụkpọ ahụ nke ultra-thin (10nm) graphite diacetylene (ihe nwere akụkụ abụọ hexagonal carbon atom monolayer jikọtara ya na agbụ succinic acid) nwere uru bara uru dị mkpa. Graphite diacetylene ọ bụghị naanị na ọ nwere ngbanwe na ịdị ike, mana usoro kemịkalụ ya na-etolitekwa netwọọdụ pore otu, na-ekwe ka naanị otu ion lithium gafere. Nke a na-achịkwa mmegharị nke ion site na akpụkpọ ahụ, na-ebute mgbasawanye nke ion nke ukwuu. N’ụzọ dị mkpa, njirimara a na-egbochi uto nke lithium dendrites n’ụzọ dị irè.

Li Yuliang nke Institute of Chemistry nke Chinese Academy of Sciences, bụ onye na-eduzi nyocha ahụ, kọwara na lithium dendrites nwere ike ime ka oghere electrolyte siri ike guzosie ike, si otú ahụ gbasaa ndụ ngwaọrụ na ike Coulomb. Gbochie sekit dị mkpụmkpụ nke yiri osisi wee rute batrị n’enweghị nsogbu.

Ndị nchọpụta kwenyere na ihe nkiri graphene-diethyne nwere ike imeri ụfọdụ n’ime nsogbu ogwugwu nke batrị lithium na batrị ígwè ndị ọzọ na-eche ihu.

Li kwuru na graphitic diacetylene bụ a getter ihe nwere hyper-conjugated Ọdịdị, pụta ụwa band ọdịiche, eke macroporous Ọdịdị na semiconductor ọrụ. Ọ na-enye nnukwu atụmanya maka idozi isi nsogbu sayensị na mpaghara a.

Data akụkụ abụọ dịkwa nnọọ mfe, ọ dịkwa mfe ịnweta n’okpuru ọnọdụ ụlọ nyocha izugbe.

Ndị na-eme nchọpụta gwara ndị nta akụkọ na ọ bụ ezie na ọ dị mkpa ka a rụkwuo ọrụ iji melite ogo ihe nkiri graphite-diacetylene n’ọtụtụ buru ibu, anyị kwenyere na graphite-diacetylene nwere ike inwe mmetụta dị egwu na nchekwa batrị lithium.
