Isesengura ryibikorwa byiterambere hamwe niterambere ryibikoresho bya cathode ya bateri ya lithium

Imikorere ya batiri ya lithium cathode igira ingaruka itaziguye kumikorere ya batiri ya lithium, kandi igiciro cyayo nacyo kigena neza ikiguzi cya batiri.Hariho uburyo bwinshi bwo gutunganya inganda kubikoresho bya cathode, inzira ya synthesis iragoye, kandi kugenzura ubushyuhe, ibidukikije, nibirimo umwanda nabyo birakomeye.Iyi ngingo izerekana uburyo bwo kubyaza umusaruro niterambere ryibikoresho bya lithium ya cathode.

Ibikoresho bya batiri ya Litiyumu kubikoresho bya cathode:

Ingufu zidasanzwe, imbaraga zidasanzwe, kutisohora wenyine, igiciro gito, ubuzima bumara igihe kirekire n'umutekano mwiza.

Litiyumu ya batiri ya cathode itunganya ibikoresho:

Tekinoroji yo kubara ikoresha tekinoroji nshya yo gukama microwave kugirango yumishe ibikoresho bya electrode nziza ya batiri ya lithium, ikemura ibibazo ko bateri isanzwe ya lithium nziza ya electrode ibikoresho byo kumisha bifata igihe kirekire, bigatuma igishoro cyihuta, gukama ntibingana, kandi ubujyakuzimu bwumye ntabwo buhagije.Ibintu byihariye ni ibi bikurikira:

1. Ukoresheje ibikoresho byo kumisha microwave kubikoresho bya cathode ya lithium, birihuta kandi byihuse, kandi byumye cyane birashobora kurangira muminota mike, bishobora gutuma ubuhehere bwanyuma bugera kubihumbi igihumbi;

2. Kuma ni kimwe kandi ubwiza bwibicuruzwa nibyiza;

3. Ibikoresho bya cathode ya batiri ya lithium irakora cyane, izigama ingufu, itekanye kandi yangiza ibidukikije;

4. Ntabwo ifite ubushyuhe bwumuriro, kandi guhita gushyuha biroroshye kugenzura.Ibikoresho bya cathode ya microwave ya litiro ya batiri ya lithium ifite ibiranga umuvuduko mwinshi, gukoresha ingufu nyinshi, gukoresha ubushyuhe bwinshi, umutekano, isuku no kutanduza umwanda, kandi birashobora kunoza uburinganire numusaruro wibicuruzwa, kandi bigateza imbere microstructure hamwe nimikorere y'ibikoresho byacumuye.

Uburyo rusange bwo gutegura ibikoresho bya lithium ya cathode:

1. Uburyo bukomeye

Mubisanzwe, imyunyu ya lithium nka karubone ya lithium na cobalt cyangwa nikel ikoreshwa mugusya no kuvanga, hanyuma reaction yo gucumura ikorwa.Ibyiza byubu buryo nuko inzira yoroshye kandi ibikoresho bibisi byoroshye kuboneka.Nuburyo bwakorewe ubushakashatsi bwimbitse, butezimbere kandi butangwa mubyiciro byambere byiterambere rya batiri ya lithium, kandi tekinoloji yamahanga irakuze;Umutekano muke hamwe nicyiciro cyiza-cy-ubuziranenge buhoraho.

2. Uburyo bukomeye

Uburyo bugoye bukoresha ibinyabuzima kugirango ubanze utegure prursor igizwe na lithium ion na cobalt cyangwa vanadium ion, hanyuma sinter kugirango utegure.Ibyiza byubu buryo ni molekuline-ivanze, ibintu byiza bihuza hamwe nibikorwa bihamye, hamwe nubushobozi buhanitse bwibikoresho bya electrode nziza kuruta uburyo bukomeye.Yageragejwe mumahanga nkuburyo bwinganda za batiri ya lithium, ariko tekinoroji ntabwo ikuze, kandi hari raporo nke mubushinwa..

3. Uburyo bwa sol-gel

Ukoresheje uburyo bwo gutegura ibice bya ultrafine byakozwe mu myaka ya za 70 kugirango utegure ibikoresho bya electrode nziza, ubu buryo bufite ibyiza byuburyo bugoye, kandi ibikoresho bya electrode byateguwe bifite imbaraga zamashanyarazi cyane, bigenda bitera imbere byihuse murugo ndetse no mumahanga.inzira.Ikibi nuko ikiguzi ari kinini, kandi ikoranabuhanga riracyari mubyiciro byiterambere.

4. Uburyo bwo guhanahana amakuru

LiMnO2 yateguwe nuburyo bwo guhanahana ion yabonye ubushobozi bwo gusohora ibintu bidasubirwaho bwa 270mA · h / g.Ubu buryo bwahindutse ubushakashatsi bushya.Ifite ibiranga imikorere ya electrode ihamye hamwe nubushobozi buhanitse.Nyamara, inzira ikubiyemo imbaraga zitwara imbaraga kandi zitwara igihe nkibisubizo byongeye kugarurwa no guhumeka, kandi haracyari intera nini mubikorwa.

Iterambere ryibikoresho bya litiro ya cathode:

Nkigice cyingenzi cya batiri ya lithium, uruganda rwamashanyarazi ya lithium cathode inganda zateye imbere byihuse.Hamwe niterambere ryinganda nshya zimodoka ninganda zibika ingufu, biteganijwe ko inganda za batiri ya lithium cathode izahinduka imbaraga zingenzi zo kuzamura inganda za cathode mubijyanye na lisiyumu yagabanijwe ya fosifate nibikoresho bya ternary muri ahazaza, kandi izatangiza amahirwe menshi.n'ibibazo.

Mu myaka itatu iri imbere, bateri ya lithium izakomeza iterambere rihamye kandi rirambye, kandi biteganijwe ko ibisabwa muri batiri ya lithium bizagera kuri 130Gwh muri 2019. Kubera kwaguka kwaguka kwinshi kwa batiri ya litiro, ibikoresho bya cathode ya lithium bikomeje gutera imbere no kwaguka .

Ubwiyongere bukabije bwibinyabiziga bishya byingufu byazanye iterambere rirambye kandi ryihuse ryinganda za batiri ya lithium.Biteganijwe ko ibikoresho bya cathode ya lithium ku isi biteganijwe ko bizarenga toni 300.000 muri 2019. Muri byo, ibikoresho bya ternary bizatera imbere byihuse, hamwe n’ikigereranyo cyo kwiyongera kwa buri mwaka kiyongereyeho 30%.Mugihe kizaza, NCM na NCA bizahinduka inzira nyamukuru yibikoresho bya cathode yimodoka.Biteganijwe ko ikoreshwa ryibikoresho bya ternary bizaba hafi 80% byibikoresho byimodoka muri 2019.

Batiri ya Litiyumu nicyerekezo cyiterambere cya batiri, kandi isoko ya cathode yibikoresho bifite ibyiringiro byiterambere.Muri icyo gihe, kuzamura amaterefone ngendanwa ya 3G hamwe n’ubucuruzi bunini bw’imodoka nshya zizana amahirwe mashya kubikoresho bya cathode ya litiro.Ibikoresho bya Litiyumu ya cathode ifite isoko ryagutse, kandi ibyiringiro ni byiza cyane.
