Litiyumu Cobalt Oxide

Amakuru y'ibanze:

Litiyumu cobalt oxyde, hamwe na formula ya chimique ya LiCoO2, ni uruganda rudasanzwe, rusanzwe rukoreshwa nkibikoresho bya electrode nziza ya batiri ya lithium.Mubisanzwe bikoreshwa muri lithium ion ibikoresho bibiri bya cathode ya cathode, inzira ya synthesis ya feri ya feri, ikoresha alcool ya polyvinyl (pVA) cyangwa polyethylene glycol (pEG) igisubizo cyamazi nkibishishwa, umunyu wa lithium hamwe numunyu wa cobalt ushonga muri pVA cyangwa igisubizo cyamazi ya pEG.Nyuma yo kuvanga, igisubizo gishyushye kugirango kibe gel, hanyuma gel irabora hanyuma ibarwa mubushyuhe bwinshi.Ifu ya cobaltate ya Litiyumu iboneka mugushungura.

Lithium cobaltate irashobora kubuza polarisiyasi ya bateri, kugabanya ingaruka zubushyuhe, kunoza imikorere yingufu, kugabanya imbaraga zimbere muri bateri, biragaragara ko igabanya imbaraga zimbere ziyongera mubikorwa byizunguruka, kunoza ubudahwema no kongera ubuzima bwikiziga. ya batiri;Nibikoresho bizwi cyane kugirango tunoze imikorere ya lithium fer fosifate nibikoresho bya lithium titanate.

Isura yacyo ni ifu yumukara.Ni okiside ikomeye mumuti wa acide, ishobora okiside CI - kuri Cl2 na Mn2 + kugeza MnO4 -.Ubushobozi bwa redox mubisubizo bya acide birakomeye kurenza ferrate, ariko birenze cyane ibya permanganate.

Ibiranga lithium cobalt oxyde:
1. Imikorere isumba iy'amashanyarazi
2. Gutunganya neza
3. Ubucucike bukabije bufasha kuzamura amajwi yihariye ya bateri
4. Igicuruzwa gifite imikorere ihamye kandi ihamye

Ibyiza bya lithium cobalt oxyde:
1. Kubuza bateri polarisiyasi, kugabanya ingaruka zumuriro no kunoza imikorere yo gukuza;
2. Kugabanya ubukana bwimbere bwa bateri, kandi ugabanye cyane imbaraga zimbere ziyongera mubikorwa byizunguruka;
3. Kunoza ubudahwema no kongera ubuzima bwa cycle ya bateri;
4. Kunoza guhuza ibikoresho bikora hamwe no gukusanya no kugabanya igiciro cyo gukora electrode;
5. Kurinda icyegeranyo cyubu kubora na electrolyte;
6. Kunoza imikorere ya lithium fer fosifate nibikoresho bya lithium titanate.
