Lilemong tsa morao tjena, indasteri e ncha ea likoloi e ntse e tsoela pele ka potlako, 'me Chaena e bile ea finyella leapfrog lefapheng la tlhahiso ea likoloi, ka theknoloji ea eona ea betri e etellang pele lefats'e. Ka kakaretso, tsoelo-pele ea theknoloji le ho eketseha ha tekanyo ea tlhahiso ho ka fokotsa litšenyehelo, ho baka boleng bo ntlafetseng le ho fokotsa litheko tsa lihlahisoa tsa ho qetela. Kajeno, sengoloa sena se sekaseka pono ea litšenyehelo tsa libeteri tse ncha tsa matla a koloi, se shebane le hore na bareki ba ka khona ho lefella likoloi tse ncha tse theko e phahameng ka mor'a thekiso ea libeteri tsa sodium-ion.
01 Sebopeho sa Litšenyehelo tsa Likoloi tse Ncha tsa Matla
Litšenyehelo tsa mantlha tsa likoloi tse hloekileng tsa motlakase lekaleng le lecha la likoloi tsa matla li batla li le tjena:
Ho tsoa ho data ho kerafo, ho hlakile hore betri ke eona ntho e kholo ka ho fetisisa e susumetsang litšenyehelo tsa koloi ka kakaretso. Ha litšenyehelo tsa betri li ntse li eketseha, ha ho pelaelo hore li fetisetsoa lihlahisoa tsa ho qetela. Joale, litšenyehelo tsa betri ea matla li khethoa joang?
02 Sebopeho sa Litšenyehelo tsa Libetri tsa Matla
Ho hlakile hore lisebelisoa tse tala ke tsona tse ka sehloohong ho khethollang litšenyehelo tsa betri ea matla. Lintlha tse lokollotsoeng ke China Automotive Power Battery Industry Innovation Alliance li bontša hore ha ho bapisoa le qalong ea selemo se fetileng, theko e tloaelehileng ea lisebelisoa tse tloaelehileng tsa ternary lithium betri cathode e nyolohile ka 108,9%, ha theko e tloaelehileng ea lithium iron phosphate battery cathode e eketsehile ka 182,5%. Ka karolelano theko ea ternary lithium battery electrolyte e eketsehile ka 146.2%, 'me ea lithium iron phosphate battery electrolyte e nyolohile ka 190.2%. Libetri tsa mantlha li ke ke tsa etsa ntle le lithium, ka hona, ha re shebeng litheko tsa lithium carbonate, lithium hydroxide, le lithium iron phosphate:
Keketseho ea litheko tsa thepa ea betri ea lithium e tsamaisoa ke mohopolo oo indasteri ea lithium e bileng le ona ka lilemo tse peli tsa ho putlama ho sa khaotseng, ho bakileng phepelo e fokotsehileng ka lebaka la tahlehelo. Leha ho le joalo, nts'etsopele e potlakileng ea likoloi tse ncha tsa matla le eona e tsamaisitse tlhokahalo ea libeteri tsa lithium. Linaha lefats'eng ka bophara li ipehetse lipakane tsa motlakase oa likoloi, ho matlafatsa khanyetsano ea tlhokahalo ea phepelo le ho lebisa ho eketseha ho tsitsitseng ha litheko tsa lisebelisoa tsa lithium battery. Boemong bo joalo, ke joang libeteri tsa motlakase li ke keng tsa eketseha ka theko?
03 Libetri tsa Sodium-ion li Hole Hakae tse nang le Ts'ebetso e Betere ea Litšenyehelo tsa Likoloi tse Ncha tsa Matla?
Ka lebaka la hore mehloli ea liminerale tsa lithium e fokotsehile haholo Lefatšeng, ho tloha ka 2020, mehloli ea lefatše ea lithium ore (lithium carbonate) e ne e le lithane tse limilione tse 128, ka lisebelisoa tsa lithane tse limilione tse 349, tse abuoang haholo linaheng tse kang Chile, Australia, Argentina le Bolivia. China e boemong ba bone ho latela mehloli e netefalitsoeng ea lithium, e ikarabellang bakeng sa 7.1%, le ea boraro tlhahisong ea ore ea lithium, e ikarabellang bakeng sa 17.1%. Leha ho le joalo, letsoai la lithium la China ha le boleng bo tlaase 'me ho thata ho hlahisa le ho sebetsa. Ka hona, China e itšetlehile haholo ka ho kenya lihlahisoa tsa lithium tsa Australia le letsoai la lithium la Amerika Boroa. Hona joale Chaena ke eona e kholo ka ho fetisisa ea bareki ba lithium lefatšeng ka bophara, e ikarabellang bakeng sa hoo e ka bang 39% ea tšebeliso ea 2019. Ka nako e khutšoanyane, mehloli ea lithium e fokotsehile ka lebaka la thepa e tsoang linaheng tse ling, 'me ka nako e telele, tsoelo-pele ea libeteri tsa lithium-ion e tla be e thibetsoe ke mehloli ea lithium. Ka hona, libeteri tsa sodium-ion, tse nang le mehloli e mengata ea polokelo, litšenyehelo le melemo ea polokeho, e ka fetoha tsela ea bohlokoa ea nts'etsopele ea indasteri ea betri nakong e tlang.
Ha e le hantle, ho tloha ka July 2021, CATL (Contemporary Amperex Technology Co., Ltd.) e ne e se e lokolitse betri ea sodium-ion 'me e phatlalalitse ho qalisoa ha mohaho oa eona oa indasteri, e nang le ketane ea motheo ea indasteri e tla thehoa ka 2023. Litaba tse ling tse monate ke hore ka July 28th selemong se fetileng, 1 GWh ea pele ea lefats'e e ne e phethiloe mohala oa tlhahiso ea sodium A Fuyang Profinseng ea Fuyang. Likoloi tse ncha tse tsamaeang ka betri ea sodium-ion ha li hole haholo.
Ho rekisoa ha likoloi tse ncha tse tsamaisoang ke betri ea sodium-ion tse nang le litšenyehelo tse ntle le hona ho tla kenya letsoho haholo kholisong ea likoloi tsa likhoerekhoere tsa motlakase metseng e meholo ho pholletsa le China. YIWEI Automotive esale e ikemiselitse ho theha le ho nts'etsopele ea chassis ea koloi e ncha e inehetseng, ho kopanya lisebelisoa tsa motlakase, nts'etsopele ea litsamaiso tse bohlale tsa taolo bakeng sa taolo ea matla a koloi, le nts'etsopele ea marang-rang a likoloi le mahlale a maholo a data. Re bile ka pele-pele indastering e inehetseng ea likoloi tse ncha tsa matla 'me re latetse haufi-ufi ka pele-pele ea theknoloji ea betri ea matla, ho tlisa bareki ba lekala la likoloi tse inehetseng tse bolokang chelete e ngata, tse sebetsang, le tse sebelisoang habonolo.
