Ka tsoelo-pele e potlakileng ea sechaba, theknoloji ea rona ea ho sebelisa lisebelisoa tsa betri ea lithium-ion le eona e ntse e tsoela pele ka potlako. Joale u utloisisa lintlha tse qaqileng tsa theknoloji ea ho hlaphoheloa ha betri ea lithium-ion? Ka mor&39;a moo, e re Xiaobian a etelle pele batho bohle ho ithuta haholoanyane ka tsebo. Libetri tsa lithium-ion li na le mefuta e mengata ea lisebelisoa, ka tšebeliso ea matlapa, li-smartphone le li-supernators, li lebeletsoe hore li be haufi le 2020, &39;me tšebeliso ea libeteri tse nyenyane tsa lithium-ion e tla hlahisa mokhoa o mocha o moholo.

Ka nako e ts&39;oanang, bothata ba ho tsosolosa palo e kholo ea libeteri tsa lithium-ion tsa litšila li hlahella haholoanyane, ho sebelisoa mekhoa ea setso e kang ho lahlela mobu, ho chesoa, joalo-joalo, e senyang, &39;me tikoloho e bakile tšilafalo, esita le ho fana ka bophelo bo botle ba batho. Kotsi.

Hona joale, naha ea heso e fetohile mohlahisi oa bohlokoa oa betri ea lithium-ion le tšebeliso ea lefats&39;e, &39;me tšebeliso ea betri e fihlile ho 8 limilione tse likete. Haeba u sena ts&39;ebetso e hlophisitsoeng ea libeteri tsa lithium-ion tse lahliloeng, tšenyo e matla ea lisebelisoa, silafatsa tikoloho le ho lematsa bophelo ba batho. Ho ka bonoa hore &39;maraka oa ho tsosolosa oa libeteri tsa lithium ion o pharaletseng.

Betri ea lithium ion e na le poleiti e ntle ea electrode le poleiti e mpe ea electrode, binder, electrolyte, le separator. Liindastering, moetsi o bohlokoa ho sebelisa lithium cobalt-cobaltate, lithium manganate, nickel-manganese acid lithium ternary material le lithium iron phosphate e le lintho tse ntle, graphite ea tlhaho le graphite ea maiketsetso e le lisebelisoa tse sebetsang ka moea. Polyvinylidene fluoride (PVDF) ke sekhomaretsi sa elektrode se sebelisoang haholo se nang le viscosity e phahameng, botsitso bo botle ba lik&39;hemik&39;hale le thepa ea &39;mele.

Tlhahiso ea indasteri ea libeteri tsa lithium ion Tšebeliso ea bohlokoa ea tharollo ea lithium hexafluorophosphate (LiPF6) le solvent organic e le electrolyte, le filimi ea tlhaho e kang polyethylene (PE) le polypropylene (PP) e sebelisoa e le diaphragm ea betri. Hangata libeteri tsa lithium-ion li nkoa e le li-betri tse tala tse sa silafatsang tikoloho, empa ho hlaphoheloa ha betri ea lithium-ion le hona ho tla baka tšilafalo. Le hoja libeteri tsa lithium-ion ha li na tšepe e boima e chefo e kang mercury, cadmium le lead, empa tšusumetso ea lintho tse ntle le tse mpe tsa electrode, electrolyte, joalo-joalo.

ea betri e ntse e le kholoanyane. Ka lehlakoreng le leng, ka lebaka la tlhokahalo e kholo ea &39;maraka ea libeteri tsa lithium ion, palo e kholo ea libeteri tsa lithium ion e tla hlaha nakong e tlang. Mokhoa oa ho sebetsana le libeteri tsena tsa lithium-ion le ho fokotsa tšusumetso ea tsona tikolohong ke bothata bo potlakileng.

Ka lehlakoreng le leng, e le ho finyella tlhokahalo e kholo ea &39;maraka, moetsi oa betri ea lithium-ion o tlameha ho hlahisa palo e kholo ea libeteri tsa lithium-ion ho fana ka&39; maraka. Libetri tsa lithium ion hangata li entsoe ka lirafshoa tse boima, metsoako ea lintho tse phelang le lipolasetiki, tse nang le karo-karolelano ea boima ba litšepe tse boima bakeng sa 15% -37%, &39;me metsoako ea organic e etsa karolo ea 15%,&39; me polasetiki e etsa 7%. Ka kakaretso, ka ho hlophisoa ha betri ea lithium ion, lisebelisoa tse sebetsang tsa electrode tse ntle, ke hore, litšepe tse boima, tikoloho, &39;me li na le boleng bo phahameng ba ho hlaphoheloa.

Ts&39;ebetso ea ho hlaphoheloa ha libeteri tsa lithium ion tsa litšila ke ea bohlokoa ho kenyelletsa le pele ho ts&39;ebetso, ts&39;ebetso ea bobeli le ts&39;ebetso e tebileng. Kaha ho ntse ho e-na le motlakase o setseng ka har&39;a betri ea litšila, ts&39;ebetso ea pele ho ts&39;ebetso e kenyelletsa mekhoa e tebileng ea ho ntša metsi, ho senya le ho hlophisa &39;mele. Sepheo sa phekolo ea bobeli ke ho arola ka ho feletseng lintho tse sebetsang tse ntle le tse mpe tsa electrode le substrates.

Hangata e qhibiliha ho sebelisoa phekolo ea mocheso le motsoako oa organic. Alkali solubility le electrolysis mokhoa hlokomela karohano e feletseng ea bobeli; ho teba kalafo Bohlokoa e kenyelletsa mekhoa e &39;meli, karohano, le ho hloekisa mekhoa e&39; meli ea ho ntša lisebelisoa tsa bohlokoa tsa tšepe. Ho ea ka lihlopha tsa ts&39;ebetso ea ho ntša, mokhoa oa ho tsosolosa betri o ka aroloa ka mekhahlelo e meraro: ho hlaphoheloa ho omileng, ho hlaphoheloa ha metsi le ho hlaphoheloa ha likokoana-hloko.

Ts&39;ebetso ea ho hlaphoheloa e metsi e silafatsoa le ho qhibiliha ho sebelisoa mochine o loketseng oa lik&39;hemik&39;hale, ebe o arola likarolo tsa tšepe ka har&39;a tharollo ea perfiltration ka ho khetheha ho hlahisa cobalt ea tšepe ea boleng bo phahameng kapa lithium carbonate, joalo-joalo. Ts&39;ebetso ea ho hlaphoheloa ha metsi e loketse haholoanyane bakeng sa ho hlaphoheloa ha likarolo tsa lik&39;hemik&39;hale tse batlang li le litšila tsa lithium-ion betri, tse nang le litšenyehelo tse tlaase tsa thepa, &39;me li loketse ho hlaphoheloa ha li-betri tse nyenyane le tse mahareng tse reriloeng litšila tsa lithium-ion. Ka hona, mokhoa ona o se o sebelisoa haholo.

Ho hlaphoheloa ho omileng ho bolela lisebelisoa tsa ho hlaphoheloa ka ho toba kapa litšepe tsa bohlokoa ntle le mecha ea litaba e kang tharollo. Har&39;a bona, tsela ea bohlokoa ea ho e sebelisa e arohane &39;meleng le mocheso o phahameng. Mishra et al.

E sebelisetsoa ho khutlisa cobalt le lithium ka betri ea lithium ion ea litšila e sebelisang eosinophilic oxide, le liphello tsa nako ea leaching, mocheso, lebelo le susumetsang le lintlha tse ling mabapi le phello ea leaching ea tšepe ea cobalt ka libeteri tsa lithium ion. Liphello li bontša hore le hoja mokhoa ona o fana ka mokhoa o mocha oa ho hlaphoheloa ha likarolo tsa cobalt, tekanyo ea leaching ea lithium acidophilic acid e tlaase haholo. Nakong e tlang, baktheria e nang le tekanyo e phahameng ea ho lema e bapisoa le mekhoa e meng, mokhoa oa ho tsoa mali oa likokoana-hloko o na le tekanyo e nyenyane ea asiti, litšenyehelo li bonolo, &39;me phello ea tikoloho e nyenyane.

Lintlha tse ka holimo ke tlhahlobo e qaqileng ea tsebo ea theknoloji ea ho hlaphoheloa ea lisebelisoa tsa betri tsa lithium ion. Hoa hlokahala ho tsoela pele ho bokella boiphihlelo bo loketseng ts&39;ebetsong, e le hore u ka rala lihlahisoa tse betere le ho ntlafatsa molemong oa sechaba sa rona.
