Muri sisitemu ya batiri ya lithium-ion yubucuruzi, ibintu bigabanya cyane cyane amashanyarazi.By'umwihariko, ubushobozi budahagije bwibikoresho bya electrode nziza bigabanya mu buryo butaziguye ibikorwa bya reaction ya electrochemic.Birakenewe kongeramo uburyo bukwiye bwo kuyobora kugirango twongere ibintu neza kandi twubake umuyoboro uyobora kugirango utange umuyoboro wihuse wo gutwara electron kandi urebe ko ibikoresho bifatika byakoreshejwe neza.Kubwibyo, umukozi uyobora ibintu nabyo ni ingenzi muri bateri ya lithium ion ugereranije nibikoresho bifatika.

Imikorere yumukozi uyobora biterwa ahanini nuburyo imiterere yibikoresho hamwe nuburyo bigenda bihura nibikoresho bifatika.Ubusanzwe ikoreshwa rya batiri ya lithium ion ikoresha ibintu bikurikira:

.Ibice byiza, urunigi rwuzuye rwuzuye, urunani runini rwubuso, hamwe nuburinganire bwibice, bifite akamaro ko gukora urunigi ruyobora muri electrode.Nkumuhagarariye ibintu gakondo bitwara ibintu, karubone yumukara nubu ikoreshwa cyane.Ikibi nuko igiciro kiri hejuru kandi bigoye gutatana.

(2)Igishushanyo.Ikora nk'urufatiro rw'urusobe ruyobora muri bateri, no muri electrode mbi, ntishobora kunoza imikorere gusa, ahubwo n'ubushobozi.

.Ikibi nuko bigoye gutatana.

(4)Carbone nanotubes (CNTs): CNT ni ibintu byayobora byagaragaye mumyaka yashize.Mubisanzwe bafite diameter ya 5nm n'uburebure bwa 10-20um.Ntibashobora gukora nk '"insinga" gusa mu miyoboro ikora, ariko kandi bigira n'ingaruka ebyiri za electrode kugirango batange gukina kurwego rwo hejuru ruranga supercapacitor.Ubushuhe bwiza bwumuriro nabwo bufasha gukwirakwiza ubushyuhe mugihe cyo kwishyuza bateri no gusohora, kugabanya polarisiyasi, kuzamura imikorere ya batiri hejuru nubushyuhe buke, no kongera igihe cya bateri.

Nkumukozi uyobora, CNTs irashobora gukoreshwa hamwe nibikoresho bitandukanye bya electrode nziza kugirango byongere ubushobozi, igipimo, hamwe nizunguruka ryibikoresho / bateri.Ibikoresho byiza bya electrode bishobora gukoreshwa harimo: LiCoO2, LiMn2O4, LiFePO4, polymer nziza electrode, Li3V2 (PO4) 3, okiside ya manganese, nibindi nkibyo.

Ugereranije nibindi bikoresho bisanzwe, karubone nanotubes ifite ibyiza byinshi nkibintu byiza kandi bibi bitwara bateri ya lithium ion.Carbone nanotubes ifite amashanyarazi menshi.Mubyongeyeho, CNTs ifite igipimo kinini kinini, kandi umubare winyongera urashobora kugera kumurongo wa percolation ugereranije nibindi byongeweho (kugumana intera ya electron mukigo cyangwa kwimuka kwaho).Kubera ko carbone nanotube ishobora gukora umuyoboro mwiza wo gutwara ibintu bya elegitoronike, agaciro kogutwara gasa nako kongeramo uduce duto duto dushobora kugerwaho hamwe na 0.2 wt% ya SWCNTs gusa.

(5)Grapheneni ubwoko bushya bwibice bibiri-byoroshye bya planar carbone ibikoresho byiza byamashanyarazi nubushyuhe bwiza.Imiterere yemerera urupapuro rwa graphene gukomera kubintu bifatika, kandi bigatanga umubare munini wibibanza byitumanaho kubintu byiza kandi bibi bya electrode ikora ibintu bifatika, kuburyo electron zishobora gukorerwa mumwanya wibice bibiri kugirango ube a umuyoboro munini uyobora imiyoboro.Kubwibyo bifatwa nkumukozi mwiza uyobora muri iki gihe.

Carbone umukara nibikoresho bifatika biri murwego rwo guhuza, kandi birashobora kwinjira mubice byibikoresho bikora kugirango byongere byimazeyo imikoreshereze yibikoresho bifatika.Carbone nanotubes iri mumurongo uhuza, kandi irashobora guhuzwa hagati yibikoresho bikora kugirango ibe imiterere y'urusobekerane, itongera gusa imiyoboro, Mugihe kimwe, irashobora kandi gukora nkigice cyo guhuza igice, nuburyo bwo guhuza graphene ni ingingo-imbonankubone, ishobora guhuza ubuso bwibikoresho bifatika kugirango habeho urusobe runini ruyobora imiyoboro nkumubiri nyamukuru, ariko biragoye gupfukirana ibintu bifatika.Nubwo ingano ya graphene yongeweho ikomeza kwiyongera, biragoye gukoresha rwose ibikoresho bifatika, no gukwirakwiza Li ion no kwangiza imikorere ya electrode.Kubwibyo, ibi bikoresho bitatu bifite inzira nziza yo kuzuzanya.Kuvanga karubone yumukara cyangwa karubone nanotubes hamwe na graphene kugirango wubake umuyoboro wuzuye wuzuye urashobora kurushaho kunoza imikorere rusange ya electrode.

Mubyongeyeho, ukurikije graphene, imikorere ya graphene iratandukanye muburyo butandukanye bwo gutegura, murwego rwo kugabanuka, ingano yurupapuro nigipimo cyumukara wa karubone, ikwirakwizwa, hamwe nubunini bwa electrode byose bigira ingaruka kuri kamere y'abakozi bayobora cyane.Muri byo, kubera ko imikorere yumukozi uyobora ari ukubaka umuyoboro uyobora ubwikorezi bwa elegitoronike, niba umukozi uyobora ubwayo adatatanye neza, biragoye kubaka umuyoboro mwiza uyobora.Ugereranije na karubone gakondo ya karubone yumukara, graphene ifite ubuso buhanitse bwubuso bwihariye, kandi effect-π conjugate ingaruka byoroha guhuriza hamwe mubikorwa bifatika.Kubwibyo, uburyo bwo gukora graphene ikora sisitemu nziza yo gukwirakwiza no gukoresha neza imikorere yayo myiza nikibazo cyingenzi kigomba gukemurwa mugukoresha graphene.
