Ndị na-eme nchọpụta nke Raunns Rifo Moore National Laboratory (LLNL) chọpụtara na ike batrị nwere ike ime ka ọ dịkwuo mma ma ọ bụrụhaala na a na-agbakwunye ihe hydrogen na electrodes nke batrị lithium-ion, nke ga-agbatị oge ọrụ ma mee ka ọrụ nnyefe dịkwuo ngwa. Batrị lithium ion bụ ụdị batrị enwere ike ịgbanye, a na-ebugharị ion lithium site na batrị gaa na electrode dị mma n&39;oge mwepu, na lithium ion nke electrode dị mma na-alaghachi na electrode na-adịghị mma n&39;oge ịchaji. Batrị lithium ion bụ ụdị batrị enwere ike ịgbanye, a na-ebugharị ion lithium site na batrị gaa na electrode dị mma n&39;oge mwepu, na lithium ion nke electrode dị mma na-alaghachi na electrode na-adịghị mma n&39;oge ịchaji.

Batrị lithium ion nwere ọtụtụ njirimara isi, voltaji, na ike ike, arụmọrụ nke njirimara ndị a na-ekpebi n&39;ikpeazụ site na nchikota nke lithium ion na electrode. Na nhazi nke electrode, mgbanwe aghụghọ na kemịl na ọdịdị nwere ike imetụta otú ion lithium siri sie ike na njikọ siri ike. Site na nnwale na ngụkọ, ndị na-eme nchọpụta nke Livermore National Lab chọpụtara na na batrị lithium-ion, hydrogen-treated graphene foam electrode na-egosipụta ikike dị elu na ikike nnyefe ngwa ngwa.

"Nchọpụta ndị a na-enye nyocha dị mma, nke na-enyere aka ịmepụta electrodes dị elu dabere na ihe graphene," ọkà mmụta sayensị ihe onwunwe LLNL Morriswang kwuru. Ọ bụkwa otu n&39;ime ndị odee nke a bipụtara na Natural Science Report (NatureScientificReports Journal). Ihe Gallene dị na ngwa azụmaahịa nke ihe nchekwa ike, gụnyere batrị lithium-ion na supercapacitors, na-emetụta ike ya imepụta ihe a na ọnụ ala dị ala.

Usoro njikọ kemịkalụ a na-ejikarị eme ihe ga-emesị hapụ ọnụ ọgụgụ dị ukwuu nke atom hydrogen, nke siri ike ịchọpụta mmetụta nke arụmọrụ electrochemical nke graphene. Nlele na Livermore Lab na-eme nchọpụta achọpụtala na ihe hydrogen na-ama ụma na-eme ka ọgwụgwọ okpomọkụ dị ala nke graphene bara ọgaranya, nke nwere ike imeziwanye ikike ọnụego. Mgbe ntụpọ nke hydrogen element na ntụpọ dị na graphene, a na-emeghe obere pore, nke nwere ike ịkwalite ion lithium dị mfe ịbanye, si otú ahụ na-eme ka ọnụego nnyefe dịkwuo mma.

Enwere ike ịnyekwu ikike ịgbagharị okirikiri site na ion lithium nke etinyere na nsọtụ ọhụrụ (yikarịrị ọ ga-arapara na mmewere hydrogen). "Nkwalite arụmọrụ nke electrode bụ ihe dị mkpa dị mkpa, nke nwere ike imeghe ngwa ngwa ụwa ọzọ," ka onye nyocha postdoctoral nke Livermore Laboratory Materials Science na onye edemede dị mkpa nke akwụkwọ nyocha kwuru. Iji tinye akwụkwọ maka ojiji nke hydrogenation na hydrogenation ntụpọ na lithium ion nchekwa Njirimara nke graphene, ndị na-eme nnyocha tinyere dị iche iche okpomọkụ ọgwụgwọ ọnọdụ kpughere site na njikọ hydrogen element, na-elekwasị anya na electrochemical Njirimara nke ya 3D graphene nanofoam (GNF).

Nke graphene nwere nkwarụ mejupụtara. Ndị nchọpụta ahụ na-eji 3D graphite nano foam n&39;ihi na ọ nwere ngwa dị iche iche nwere ike ime, gụnyere nchekwa hydrogen, catalysis, filtration, mkpuchi, ike absorption, capacitance desal, supercapacitors na lithium-ion batrị, wdg. Njirimara nke graphene 3D foam na-abụghị nrapado enweghị ike ịdị mgbagwoju anya n&39;ihi na mgbakwunye na-agbagwoju anya, ya mere enwere ike iji ya dị ka nhọrọ dị mma maka nyocha usoro.

"Anyị chọpụtara na mgbe ọgwụgwọ nke hydrogen element, graphite olee foam electrode nwere ọganihu dị ịrịba ama. Site na nchikota nke nnwale a, anyị ga-esochi mmekọrịta dị nro na ọganihu dị n&39;etiti ntụpọ na ngwọta hydrogen. Na nzaghachi nye nsonaazụ nke ụfọdụ obere mgbanwe na graphene kemịkalụ na morphology, ọ ga-ekwe omume iweta mmetụta dị ịtụnanya na arụmọrụ, "Ndị nchọpụta LLNL nwekwara onye edemede ọzọ nke ọmụmụ a" Brandonwood.

Dị ka ọmụmụ a si kwuo, a pụkwara iji ọgwụgwọ mmewere hydrogen a na-achịkwa na ihe anode ndị ọzọ dabeere na graphene iji nweta mgbasa ozi lithium ion kachasị mma na ngwa nchekwa a na-emegharịgharị.
