Mokhoa o akaretsang oa ho lokisa lisebelisoa tsa lithium battery cathode:

1. Mokhoa o tiileng oa mohato

Ka kakaretso, matsoai a lithium a kang lithium carbonate le cobalt metsoako kapa metsoako ea nickel e sebelisoa bakeng sa ho sila le ho kopanya, ebe karabelo ea sintering e etsoa.Melemo ea mokhoa ona ke hore mokhoa ona o bonolo 'me lisebelisoa tse tala li fumaneha habonolo.Ke ea mokhoa o 'nileng oa batlisisoa ka ho pharaletseng, o hlahisitsoeng le ho hlahisoa qalong ea tsoelo-pele ea lithium betri,' me theknoloji ea linaheng tse ling e batla e hōlile;Botsitso bo fokolang le ho se tsitse ha boleng ba batch-to-batch.

2. Mokhoa o rarahaneng

Mokhoa o rarahaneng o sebelisa motsoako oa manyolo ho qala ho lokisa selelekela se rarahaneng se nang le lithium ion le cobalt kapa vanadium ion, ebe sinter ho itokisetsa.Melemo ea mokhoa ona ke ho kopanya limolek'hule, ho tšoana hantle ha thepa le botsitso ba ts'ebetso, le bokhoni bo phahameng ba lisebelisoa tsa electrode tse ntle ho feta mokhoa o tiileng oa mohato.E 'nile ea lekoa linaheng tse ling e le mokhoa oa indasteri bakeng sa libeteri tsa lithium, empa theknoloji ha e ea hōla,' me ho na le litlaleho tse fokolang Chaena..

3. Mokhoa oa Sol-gel

Ho sebelisa mokhoa oa ho lokisetsa likaroloana tsa ultrafine tse entsoeng lilemong tsa bo-1970 ho lokisetsa lisebelisoa tse ntle tsa electrode, mokhoa ona o na le melemo ea mokhoa o rarahaneng, 'me thepa e lokiselitsoeng ea electrode e na le matla a motlakase a ntlafetseng haholo, a ntseng a tsoela pele ka potlako lapeng le linaheng tse ling.tsela.Bothata ke hore litšenyehelo li phahame, 'me theknoloji e ntse e le sethaleng sa nts'etsopele.

4. Mokhoa oa phapanyetsano oa ion

LiMnO2 e lokiselitsoeng ka mokhoa oa phapanyetsano ea ion e fumane matla a phahameng a ho lahla a 270mA · h / g.Mokhoa ona o fetohile sebaka se secha sa lipatlisiso.E na le litšobotsi tsa ts'ebetso e tsitsitseng ea electrode le bokhoni bo phahameng.Leha ho le joalo, ts'ebetso ena e kenyelletsa mehato e jang matla le e senyang nako joalo ka tharollo ea recrystallization le mouoane, 'me ho ntse ho le hole haholo le ts'ebetso.

Mokhoa oa nts'etsopele ea lisebelisoa tsa lithium battery cathode:

E le karolo ea bohlokoa ea libeteri tsa lithium, indasteri ea matla ea naha ea heso ea lithium battery cathode e tsoetse pele ka potlako.Ka nts'etsopele ea indasteri e ncha ea likoloi tsa matla le indasteri ea polokelo ea matla, ho lebelletsoe hore indasteri ea lisebelisoa tsa lithium battery cathode e tla ba eona e ka sehloohong e susumetsang kholo ea indasteri ea thepa ea cathode ho latela likarolo tse arohaneng tsa lithium iron phosphate le lisebelisoa tsa ternary. bokamoso, mme e tla tlisa menyetla e mengata.le mathata.
