Ho latela lintlha tsa Gartner: Ka 2025, matla a lefats'e a betri ea lithium a tla fihla ho 5.7 bilione Ah, ka sekhahla sa kholo ea selemo le selemo sa 21.5%. Ka tsoelo-pele ea thekenoloji le taolo ea litšenyehelo, betri ea Li-ion e fetohile mokhoa oa tlhōlisano oa theko ho feta betri ea setso ea lead-acid ka betri e ncha ea matla a koloi.
1.Tsela tsa Theknoloji
Theknoloji ea betri ea lithium e ntse e tsoela pele ho ntlafala, ho tloha nakong e fetileng ea lisebelisoa tsa ternary ho ea ho matla a phahameng a matla a lithium iron phosphate, hona joale ke phetoho ho lithium iron phosphate le lisebelisoa tsa ternary, mme ts'ebetso ea cylindrical ke eona e ka sehloohong. Sebakeng sa lisebelisoa tsa elektronike tsa bareki, libeteri tsa cylindrical lithium iron phosphate butle-butle li nkela sebaka sa li-betri tsa cylindrical le square lithium iron phosphate; ho tloha lits'ebetsong tsa betri ea matla, ho tloha qalong ea ts'ebeliso ho fihlela joale, karolo ea lits'ebetso tsa betri ea matla e ntse e eketseha selemo le selemo. Linaha tsa morao-rao tse tloaelehileng tsa linaha tsa machaba karo-karolelano ea tšebeliso ea betri ea matla e ka bang 63%, e lebelletsoe ho fihla hoo e ka bang 72% ka 2025. Nakong e tlang, ka tsoelo-pele ea theknoloji le taolo ea litšenyehelo, sebopeho sa sehlahisoa sa lithium betri se lebelletsoe ho tsitsa le ho hlahisa 'maraka o pharaletseng. sebaka.
2.Maemo a Maraka
Li-ion battery ke mofuta o sebelisoang ka ho fetisisa oa betri ea matla 'me e na le mefuta e mengata ea lisebelisoa tšimong ea likoloi tse ncha tsa matla,' me tlhokahalo ea 'maraka ea betri ea Li-ion e kholo. Ah, e nyolohile ka 44.2% selemo le selemo. Har'a bona, tlhahiso ea Ningde Times e ne e le 41,7%; BYD e behile boemo ba bobeli, ka 18.9% ea tlhahiso. Ka keketseho e tsoelang pele ea matla a tlhahiso ea likhoebo, mokhoa oa tlholisano oa indasteri ea betri ea lithium o ntse o mpefala le ho feta, Ningde Times, BYD le likhoebo tse ling li ntse li tsoela pele ho holisa karolo ea bona ea mmaraka ka melemo ea tsona, ha Ningde Times e fihletse tšebelisano ea maano le eona. Samsung SDI mme e fetohile e mong oa barekisi ba ka sehloohong ba betri ea matla ea Samsung SDI; BYD e ntse e tsoela pele ho eketsa matsete a eona lefapheng la matla a matla ka lebaka la melemo ea eona ea tekheniki, 'me e se e le BYD ea moralo oa tlhahiso ea matla tšimong ea betri ea matla e ntlafetse butle-butle mme e kene sethaleng sa tlhahiso e kholo; BYD e na le tsebo e tebileng le e pharaletseng ea lisebelisoa tse tala tsa lithium, lisebelisoa tsa eona tse phahameng tsa nickel ternary lithium, lihlahisoa tsa tsamaiso ea graphite li khonne ho finyella litlhoko tsa lik'hamphani tse ngata tsa lithium betri.
3.Tlhahlobo ea sebopeho sa lisebelisoa tsa betri ea lithium
Ho tsoa ho sebopeho sa lik'hemik'hale, ho na le lisebelisoa tsa cathode haholo (ho kenyeletsoa lisebelisoa tsa lithium cobaltate le lithium manganate), lisebelisoa tse mpe tsa electrode (ho kenyeletsoa lithium manganate le lithium iron phosphate), electrolyte (ho kenyeletsoa tharollo ea sulfate le tharollo ea nitrate), le diaphragm (ho kenyeletsoa LiFeSO4 le LiFeNiO2). Ho tloha ts'ebetsong ea thepa, e ka aroloa ka lisebelisoa tse ntle le tse mpe tsa electrode. Libetri tsa lithium-ion hangata li sebelisa cathode ho ntlafatsa ts'ebetso ea ho tjhaja, ha li ntse li sebelisa lithium joalo ka thepa ea cathode; electrode e mpe e sebelisang motsoako oa nickel-cobalt-manganese; lisebelisoa tsa cathode haholo-holo li kenyelletsa NCA, NCA + Li2CO3 le Ni4PO4, joalo-joalo; electrode e mpe e le betri ea ion ka har'a thepa ea cathode le diaphragm ke eona ea bohlokoa ka ho fetisisa, boleng ba eona bo ama ka kotloloho ts'ebetso ea libeteri tsa lithium-ion. Bakeng sa ho fumana tefo e phahameng le ho ntša matla a khethehileng le bophelo bo bolelele, lithium e tlameha ho ba le ts'ebetso e phahameng le litšobotsi tsa bophelo bo bolelele. Li-electrode tsa lithium li arotsoe ka libeteri tsa boemo bo tiileng, libeteri tsa metsi le libeteri tsa polymer ho ea ka thepa, eo lisele tsa mafura a polymer e leng theknoloji e batlang e hōlile e nang le melemo ea litšenyehelo 'me e ka sebelisoa ka liselefouno le lisebelisoa tse ling tsa elektronike tsa bareki; matla a boemo bo tiileng ka lebaka la matla a mangata a matla le litšenyehelo tse tlaase tsa tšebeliso, tse loketseng ho boloka matla le masimo a mang; le matla a polymer ka lebaka la matla a tlase a matla le theko e tlase empa khafetsa ea tšebeliso, e loketseng lithium battery pack. Lisele tsa mafura a polymer li ka sebelisoa ka liselefouno, lilaptop le lik'hamera tsa dijithale; thekenoloji ea betri ea boemo bo tiileng ha joale e mothating oa liteko.
Ts'ebetso ea 4.Manufacturing le tlhahlobo ea litšenyehelo
Libetri tsa elektronike tsa Consumer lithium li etsoa ho sebelisoa lisele tse phahameng tsa motlakase, tseo haholo-holo li entsoeng ka lisebelisoa tsa electrode tse ntle le tse mpe le lisebelisoa tsa diaphragm. Ts'ebetso le litšenyehelo tsa lisebelisoa tse fapaneng tsa cathode li fapana haholo, moo ts'ebetso e ntle ea lisebelisoa tsa cathode, theko e tlase, ha ts'ebetso e mpe ea lisebelisoa tsa diaphragm, theko e phahame. Ho latela data ea China Industry Information Network e bonts'a hore lisebelisoa tsa elektronike tsa lithium betri tse ntle le tse mpe li etsa karolo ea 50 ho isa ho 60% ea litšenyehelo tsohle. Thepa e ntle e entsoe haholo-holo ka thepa e mpe empa litšenyehelo tsa eona li ikarabella ho feta 90%, 'me ka theko e mpe ea thepa e eketsehang, theko ea sehlahisoa e ile ea eketseha butle-butle.
5.Thepa e tšehetsang litlhoko tsa thepa
Ka kakaretso, lisebelisoa tsa kopano ea betri ea lithium li kenyelletsa mochine oa ho bopa ka ente, mochini oa laminating, le mohala o chesang oa ho qeta, joalo-joalo mochini oa ho kenya ente: o sebelisetsoang ho hlahisa libethe tsa lithium tse boholo bo boholo, tse sebelisoang haholo ho ba le tekanyo e phahameng haholo ea ho iketsetsa bakeng sa ts'ebetso ea kopano, ha e ntse e na le tiiso e ntle. Ho ea ka tlhokahalo ea tlhahiso, e ka hlomelloa ka liforomo tse tsamaellanang, e le ho hlokomela ho itšeha ho nepahetseng ha thepa ea ho paka (konokono, lisebelisoa tse mpe, diaphragm, joalo-joalo) le enfelopo. Mochini oa stacking: Thepa ena e sebelisoa haholo ho fana ka mokhoa oa ho bokella matla a lithium betri, eo haholo-holo e nang le likarolo tse peli tse kholo: lebelo le phahameng la stacking le tataiso ea lebelo le phahameng.
