Imodoka nshya yingufu za lithium anode irimotungsten oxyde WO3 nanoparticles.

Mu gukora ibinyabiziga bishya byingufu, gukoresha ibikoresho bya lithium anode irimo oxyde ya tungsten yumuhondo birashobora gutanga ingufu za batiri yumuriro no kuzamura imikorere yikinyabiziga.
Ku bijyanye n’inganda nshya z’ibinyabiziga bitanga ingufu, igice cya batiri ni ishingiro ry’ikoranabuhanga ry’amashanyarazi atatu. Nkuko abakozi babishinzwe babivuga, muri 2019, icyiciro cya mbere cy’ibinyabiziga bishya by’ingufu za ingufu za 160Wh / Kg cyangwa zirenga , moderi zose hamwe 15, ukurikije BYD, CITIC Guoan, Itsinda rya GAC, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri. ko mugikorwa cyo gukora ibikoresho bya lithium anode, kongeramo okiside ya nano yumuhondo tungsten oxyde irashobora gutuma bateri ikora neza, hanyuma igateza imbere guhangana mumodoka nshya yingufu kumasoko mpuzamahanga.Impamvu ituma uduce twa oxyde tungsten yumuhondo nano nini cyane ikoreshwa nkibikoresho bya lithium anode nuko okiside yumuhondo tungsten ifite ibyiza byubwinshi bwingufu nigiciro gito.

Nano umuhondo tungsten trioxide, ifu ya WO3, ni ibikoresho bidasanzwe bya N-semiconductor ibikoresho, bishobora gukoreshwa mugutegura ibikoresho bya electrode bikoresha amafaranga menshi, ni ukuvuga ko bateri ya lithium yateguwe byihuse ntabwo ifite imikorere y’amashanyarazi gusa, ahubwo ikanagabanya igiciro cy’umusaruro. Ugereranije na bateri zisa muri isoko, bateri ya lithium irimo ifu ya nanometero tungsten ifata imikoreshereze yagutse, kandi irashobora gutanga ingufu zihagije kubinyabiziga bishya byingufu, ibikoresho byamashanyarazi, terefone igendanwa ikoraho, mudasobwa zigendanwa nibindi bikoresho.

Batteri ya lithium ya Ternary hamwe na batiri ya lithium fer fosifate ifata umwanya munini wisoko.Nyamara, bafite bimwe mubitagenda neza, nkumwanya muto wo kuzamura ubucucike bwingufu.Mu ntego, abahanga bibanda kubushakashatsi bwibikoresho bya anode na cathnode.

Iterambere ryikoranabuhanga ryibikoresho bya lithium cathode

Orthosilicate, igizwe na lithium ikungahaye kuri manganese, ibikoresho bya cathode ya sulfide nubushakashatsi bugezweho bishyushye.Mu nyigisho, orthosilicate irashobora kwemerera guhanahana 2 Li +, ifite ubushobozi bwihariye bwihariye, ariko muburyo bwo kurekura, ubushobozi nyabwo ni kimwe cya kabiri cyubushobozi bwa theoretical. Usibye ingufu zidasanzwe, lithium ikungahaye kuri manganese base ifite ibyiza byigiciro cyiza.Mbere yibi, birakenewe gushakisha uburyo bukwiye bwo kubyaza umusaruro.Ibikoresho bya cathode bishingiye kuri sulfure bifite ingufu zingana na 2600Wh / kg, ariko kwaguka kwinshi biroroshye kugaragara muburyo bwo kwishyuza no gusohora, bigomba kunozwa.
Iterambere ryikoranabuhanga ryibikoresho bya lithium anode

Graphene, lithium titanate na nano yumuhondo tungsten oxyde ni ibikoresho bya lithium anode ishishikaye cyane.Graphene irashobora gukoreshwa nkibikoresho bitwara ibintu nabi kugirango ikore ibihimbano hamwe nibikoresho byiza kandi bibi, ariko ntishobora gukoreshwa mubwinshi nkibintu bifatika byo gusimbuza grafite ibikoresho bya anode.Litiyumu titanate ifite ubuzima burebure, kugeza inshuro zirenga 10,000, kandi irashobora kwishyurwa vuba, bikwiranye n'umwanya ntibisaba umwanya wo kubika ingufu.Nano yumuhondo tungsten oxyde ni ibikoresho bidasanzwe bya electrode ifite ubushobozi bwa 693mAh / g nibikorwa byiza bya electrochromic.Mubyongeyeho, ifite ibyiza byigiciro gito, ibigega byinshi hamwe nuburozi.

Mu gusoza, nano-nini ya tungsten oxyde WO3 irashobora gukoreshwa nkibikoresho bya electrode kandi bigakoreshwa mumodoka nshya yingufu.

Guangzhou Hongwu Material Technology Co., Ltd. iratanganano umuhondo tungsten trioxide WO3ku bwinshi, hamwe nibisohoka buri kwezi birenga toni 2.Dutwarwa nibinyabiziga bishya byingufu, tugenda twagura buhoro buhoro umurongo utanga umusaruro, dutanga ibicuruzwa byiza kumasoko, kandi dutanga umusanzu uciriritse murwego rushya rwingufu.
