01 Sebopeho sa Litšenyehelo tsa Likoloi tse Ncha tsa Matla
Likarolo tse ka sehloohong tsa litšenyehelo tsa likoloi tsa motlakase tse hloekileng lefapheng la likoloi tse ncha tsa matla ke tse latelang:
Ho latela data e kerafong, ho totobetse hore betri ke ntlha e kholo ka ho fetisisa e susumetsang litšenyehelo tsa koloi ka kakaretso. Ha litšenyehelo tsa betri li ntse li eketseha, li fetisetsoa lihlahisoa tsa ho qetela ka mokhoa o ke keng oa qojoa. Joale, litšenyehelo tsa betri ea motlakase li fumanoa joang?
02 Sebopeho sa Litšenyehelo tsa Libetri tsa Motlakase
Ho hlakile hore thepa e tala ke ntlha ea bohlokoa ho khethoeng ha litšenyehelo tsa betri ea motlakase. Lintlha tse lokollotsoeng ke Mokhatlo oa Chaena oa Batri ea Matla a Likoloi oa Chaena li bontša hore ha ho bapisoa le qalong ea selemo se fetileng, theko e tloaelehileng ea thepa e tloaelehileng ea cathode ea betri ea lithium e nyolohile ka 108.9%, ha theko e tloaelehileng ea thepa ea cathode ea betri ea lithium iron phosphate e eketsehile ka 182.5%. Theko e tloaelehileng ea li-electrolyte tsa betri ea lithium ternary e eketsehile ka 146.2%, 'me ea li-electrolyte tsa betri ea lithium iron phosphate e eketsehile ka 190.2%. Libetri tse tloaelehileng li ke ke tsa phela ntle le lithium, kahoo ha re shebeng mekhoa ea litheko tsa lithium carbonate, lithium hydroxide, le lithium iron phosphate:
Keketseho ea litheko tsa thepa ea betri ea lithium e susumetsoa ke mohopolo oo indasteri ea lithium e bileng le oona ka lilemo tse peli tsa ho putlama ho sa khaotseng, e leng se ileng sa fella ka phokotso ea phepelo ka lebaka la tahlehelo. Leha ho le joalo, nts'etsopele e potlakileng ea likoloi tse ncha tsa eneji le eona e susumelitse tlhoko ea libeteri tsa lithium. Linaha lefatšeng ka bophara li ipehetse lipheo tsa ho kenya motlakase likoloing, e leng se matlafatsang khanyetsano ea phepelo le tlhoko le ho lebisa keketsehong e tsoelang pele ea litheko tsa mehloli ea libeteri tsa lithium. Boemong bo joalo, libeteri tsa motlakase li ka se nyolohe joang ka theko?
03 Libetri tsa Sodium-ion tse nang le Tshebetso e Ntle ea Litšenyehelo li Hole Hakae bakeng sa Likoloi tse Ncha tsa Matla?
Kaha mehloli ea liminerale tsa lithium e fokotsehile haholo Lefatšeng, ho tloha ka 2020, mehloli ea lefats'e ea lithium ore (lithium carbonate) e ne e le lithane tse limilione tse 128, ka mehloli ea lithane tse limilione tse 349, haholo-holo linaheng tse kang Chile, Australia, Argentina le Bolivia. Chaena e boemong ba bone ka mehloli ea lithium e pakiloeng, e ikarabellang bakeng sa 7.1%, 'me ea boraro tlhahisong ea lithium ore, e ikarabellang bakeng sa 17.1%. Leha ho le joalo, letsoai la lithium la Chaena ha le na boleng bo botle 'me ho thata ho le hlahisa le ho le sebetsana. Ka hona, Chaena e itšetlehile haholo ka ho kenya li-concentrate tsa lithium tsa Australia le letsoai la lithium la Amerika Boroa. Chaena hajoale ke moreki e moholo ka ho fetisisa oa lithium lefatšeng ka bophara, e ikarabellang bakeng sa hoo e ka bang 39% ea ts'ebeliso ka 2019. Ka nako e khuts'oane, mehloli ea lithium e lekanyelitsoe ka lebaka la ho kena ka ntle ho naha, 'me ka nako e telele, nts'etsopele ea libeteri tsa lithium-ion e tla thibeloa ke mehloli ea lithium. Ka hona, libeteri tsa sodium-ion, tse nang le mehloli e mengata ea litšireletso, litšenyehelo le melemo ea polokeho, e ka ba tsela ea bohlokoa ea nts'etsopele bakeng sa indasteri ea libeteri nakong e tlang.
Ha e le hantle, ho tloha ka Phupu 2021, CATL (Contemporary Amperex Technology Co., Ltd.) e ne e se e lokolotse betri ea sodium-ion mme e phatlalalitse ho qalisoa ha moralo oa eona oa indasteri, 'me ketane ea mantlha ea indasteri e tla theoa ka 2023. Litaba tse ling tse monate ke hore ka la 28 Phupu selemong se fetileng, mohala oa pele oa lefats'e oa tlhahiso ea betri ea sodium-ion ea 1 GWh o ile oa phethoa Fuyang, Profinseng ea Anhui. Likoloi tse ncha tsa eneji tse tsamaisoang ke betri ea sodium-ion ha li hole haholo.
Khoebo ea likoloi tse ncha tsa eneji tse tsamaisoang ke betri ea sodium-ion ka ts'ebetso e ntle ea litšenyehelo le eona e tla kenya letsoho haholo ho ntšetseng pele likoloi tsa bohloeki ba motlakase metseng e meholo ho pholletsa le Chaena. YIWEI Automotive esale e ikemiselitse ho rala le ho nts'etsapele chassis ea likoloi tse ncha tsa eneji tse inehetseng, ho kopanya litsamaiso tsa motlakase, nts'etsopele ea litsamaiso tse bohlale tsa taolo bakeng sa taolo ea motlakase e kentsoeng likoloing, le nts'etsopele ea marang-rang a likoloi le mahlale a data e kholo. Re bile ka pele ho indasteri ea likoloi tse ncha tsa eneji tse inehetseng 'me re latetse haufi-ufi theknoloji ea betri ea motlakase, re tlisa bareki lefapheng la likoloi tse inehetseng likoloi tse ncha tsa eneji tse theko e tlaase haholoanyane, tse sebetsang, le tse bonolo ho li sebelisa.
