Tlhahlobo ea nako ea nalane ea mohloli oa lisebelisoa tsa lithium battery cathode
Tlhahlobo ea thepa ea cathode
Ka 2012, libeteri tsa lithium li ne li etsa karolo ea 41% ea tlhokahalo ea lefats’e ea lithium terminal. Ts’ebetso ea ho kenya le ho tsoa ha betri ea lithium e itšetlehile ka sebopeho le ts’ebetso ea data e ka hare ea betri. Lintlha tse ka hare tsa betri li kenyelletsa tlhahisoleseding e mpe, electrolyte, membrane le tlhahisoleseding e ntle. Lintlha tse ntle ke lintlha tsa bohlokoa tsa bohlokoa, tse ikarabellang bakeng sa 30-40% ea litšenyehelo tsa libeteri tsa lithium. Katoloso e potlakileng ea mabenkele a lisebelisoa tsa elektroniki tsa bareki (lilaptop, matlapa, lifono tse bohlale, joalo-joalo) e lebisitse ho eketseha ha tlhokahalo ea libeteri tsa lithium. Nakong e tlang, likoloi tsa motlakase le limela tsa polokelo ea matla lefapheng le lecha la matla le tsona li tla itšetleha ka libeteri tsa lithium. Ka 2013, indasteri ea lefats’e ea betri ea lithium e lebelletsoe ho fihla ho lidolara tse limilione tse likete tse 27.81 tsa Amerika. Ka 2015, ts’ebeliso ea indasteri ea likoloi tse ncha tsa matla e tla khanna indasteri ea lefats’e ea lithium betri ho fihlela US $ 52.22 limilione tse likete. Ka ho atolosoa ha leano la indasteri ea betri ea lithium, Positive Data’s lithium battery industry plan le eona e boemong ba ho atolosa ka potlako, ‘me tšebeliso ea lithium cobalt oxide ke eona e hōlileng ka ho fetisisa.
Sebedisa ho bola ha sehlopha ka data e nepahetseng
Lintlha tse ntle tsa libeteri tsa lithium tse ntseng li sebelisoa le ho ntlafatsoa haholo-holo li entsoe ka data ea ternary ea lithium cobalt acid, lithium nickel cobalt acid, nickel manganese cobalt, spinel lithium manganese acid le olivine lithium iron phosphate. Naheng ea heso, data ea cathode haholo-holo e kenyelletsa lithium cobalt oxide, data ea ternary, lithium manganate le lithium iron phosphate. Ho senyeha ha sehlopha sa kopo ea data e ntle ho bohlokoa haholo. Lithium cobalt oxide e ntse e le mohloli oa bohlokoa oa data e nepahetseng bakeng sa libeteri tse nyane tsa lithium, hape e bohlokoa haholo bakeng sa libeteri tsa setso tsa 3C tsa lithium. Lintlha tsa Ternary le lithium manganese oxide ke likarolo tsa bohlokoa tsa libeteri tse nyane tsa lithium. Japane le Korea Boroa, theknoloji ea betri e batla e hōlile ‘me e bohlokoa bakeng sa lisebelisoa tsa motlakase, libaesekele tsa motlakase le likoloi tsa motlakase. Lithium iron phosphate e sebelisoa haholo naheng ea heso mme ke tataiso ea nts’etsopele ea nakong e tlang. E na le boleng ba ts’ebeliso ea bohlokoa masimong a setsi sa setsi le polokelo ea matla ea setsi sa data, polokelo ea matla a lapeng, le polokelo ea matla a letsatsi.
Lithium cobalt oxide e tla nkeloa sebaka butle-butle
Ts’ebetso ea tlhahiso ea lithium cobalt oxide e bonolo, ts’ebetso ea electrochemical e tsitsitse, ‘me ke e’ ngoe ea melemo ea pele ea khoebo e feletseng. E na le melemo ea matla a phahameng a discharge, charger e tsitsitseng le voltage discharge, le tekanyo e phahameng ea matla. E na le lits’ebetso tsa bohlokoa ho lihlahisoa tse nyane tsa bareki ba betri. Mmaraka oa lisebelisoa tsa elektronike tsa bareki o ntse o tsoela pele ka potlako, ‘me thekiso ea thepa ea lithium cobalt oxide battery cathode e etsa karolo e kholo ka ho fetisisa, empa chelete e phahameng ha e thuse ho sireletsa tikoloho, tekanyo ea tšebeliso ea matla e tlaase, bophelo ba betri bo khutšoanyane,’ polokeho e fokola. Lintlha tsa Ternary li kopanya melemo ea lithium cobalt, lithium nickel le lithium manganese ‘me e na le phaello ea theko, empa tšebeliso ea eona e angoa ke theko ea cobalt. Ha theko ea cobalt e phahame, theko ea data ea ternary e tlase ho feta ea cobalt lithium, e nang le tlhōlisano e matla ea ‘maraka. Empa ha theko ea cobalt e theohile, molemo oa data ea triad e amanang le cobalt le lithium e nyane haholo. Hajoale, ho nkeloa sebaka ha data ea lithium oxide ke data ea ternary ke mokhoa o akaretsang.
Lintlha tsa Ternary li na le molemo oa litšenyehelo tse tlase
Lintlha tsa ternary li lokisoa ka ho hlahisa nickel, cobalt le manganese ka tekanyo e itseng, ebe ho hlahisa mohloli oa lithium. Koloi ea pele ea lipapali ea Tesla e sebelisitse libeteri tsa 18650 tsa lithium cobalt oxide, ha mohlala oa eona oa bobeli oa tlhahiso ea Model-s o sebelisitse betri ea Panasonic e hlophisitsoeng ea Ternary-Data, e leng betri ea nickel-cobalt-aluminium. Ternary-PositiveData betri. Libetri tsa lithium cobalt oxide li theko e boima, kahoo hoa utloahala ho bapisa ts’ebetso ea mefuta e ‘meli pele le ka morao ho Tesla. Model s e sebelisa libeteri tse fetang 8,000, tse fetang 1,000 ho feta Roadster. Leha ho le joalo, ka lebaka la taolo e ntle ea litšenyehelo tsa betri ea litsela tse 3, litšenyehelo li fokotsehile ka 30%. Hajoale, ho ntse ho e-na le lekhalo le leholo pakeng tsa data ea naha ea heso e phahameng ea lithium betri NCM ternary le ‘maraka oa machaba,’ me ho na le litšitiso tse peli tse kholo tsa thepa le thekenoloji ea taolo ea botsitso, ‘me ho hlakile hore tsoelo-pele e salla morao. E ‘nile ea sebelisoa haholo linaheng tse ling, empa k’hamphani ea rona ha e na lihlahisoa leha ho le joalo.
