Ka nts'etsopele e potlakileng ea indasteri e ncha ea matla, tlhoko ea libeteri tsa lithium tse sebetsang hantle e ntse e eketseha. Leha lisebelisoa tse kang lithium iron phosphate (LFP) le ternary lithium li lula li le maemong a holimo, sebaka sa tsona sa ntlafatso ea matla a matla se na le moeli, 'me polokeho ea tsona e ntse e hloka ho ntlafatsoa le ho feta. Haufinyane tjena, metsoako e thehiloeng ho zirconium, haholo-holo zirconium tetrachloride (ZrCl₄) le lihlahisoa tsa eona, butle-butle li fetohile sebaka sa lipatlisiso ka lebaka la bokhoni ba tsona ba ho ntlafatsa bophelo ba potoloho le polokeho ea libeteri tsa lithium.
Monyetla le melemo ea zirconium tetrachloride
Tšebeliso ea zirconium tetrachloride le lihlahisoa tsa eona ho libeteri tsa lithium e bonahala haholo-holo likarolong tse latelang:
1.Ho ntlafatsa bokhoni ba phetisetso ea ion:Boithuto bo bonts'itse hore li-additives tsa metal organic framework (MOF) tse nang le libaka tse tlase tsa Zr⁴⁺ li ka ntlafatsa haholo ts'ebetso ea phetisetso ea li-ion tsa lithium. Tšebelisano e matla lipakeng tsa libaka tsa Zr⁴⁺ le sheath ea lithium ion solvation e ka potlakisa ho falla ha li-ion tsa lithium, kahoo ea ntlafatsa tšebetso ea lebelo le bophelo ba potoloho ea betri.
2.Enhanced interface botsitso:Li-derivatives tsa zirconium tetrachloride li ka fetola sebopeho sa solvation, tsa ntlafatsa botsitso ba sebopeho pakeng tsa electrode le electrolyte, le ho fokotsa ho hlaha ha karabelo ea lehlakore, ka hona ho ntlafatsa polokeho le bophelo ba tšebeletso ea betri.
Tekanyo lipakeng tsa litšenyehelo le ts'ebetso: Ha ho bapisoa le lisebelisoa tse ling tse tiileng tsa electrolyte tse theko e phahameng, theko ea thepa e tala ea zirconium tetrachloride le lintho tse tsoang ho eona e batla e le tlase. Ka mohlala, theko ea thepa e tala ea li-electrolyte tse tiileng tse kang lithium zirconium oxychloride (Li1.75ZrCl4.75O0.5) ke $ 11.6 / kg feela, e leng tlase haholo ho feta li-electrolyte tse tiileng tsa setso.
Ha ho bapisoa le lithium iron phosphate le ternary lithium
Lithium iron phosphate (LFP) le ternary lithium ke lisebelisoa tse ka sehloohong tsa libeteri tsa lithium hajoale, empa e 'ngoe le e 'ngoe e na le melemo le likotsi tsa eona. Lithium iron phosphate e tsejoa ka polokeho ea eona e phahameng le bophelo ba potoloho e telele, empa matla a eona a matla a tlase; ternary lithium e na le matla a mangata a matla, empa polokeho ea eona e batla e fokola. Ka lehlakoreng le leng, tetrachloride ea zirconium le lihlahisoa tsa eona li sebetsa hantle ho ntlafatsa katleho ea phetisetso ea ion le botsitso ba li-interface, 'me ho lebeletsoe ho etsa hore ho be le mefokolo ea thepa e teng.
Mathata le mathata a khoebo
Leha zirconium tetrachloride e bonts'itse bokhoni bo boholo lipatlisisong tsa laboratori, khoebo ea eona e ntse e tobana le mathata a mang:
1.Khōlo ea ts'ebetso:Hona joale, ts'ebetso ea tlhahiso ea zirconium tetrachloride le lihlahisoa tsa eona ha e e-s'o hōle ka ho feletseng, 'me botsitso le botsitso ba tlhahiso e kholo e ntse e hloka ho netefatsoa ka ho eketsehileng.
2. Taolo ea litšenyehelo:Leha theko ea thepa e tala e le tlase, tlhahisong ea 'nete, lintlha tsa litšenyehelo tse kang ts'ebetso ea ho kopanya le matsete a lisebelisoa li hloka ho nahanoa.
Kamohelo ea 'maraka: Lithium iron phosphate le ternary lithium li se li nkile karolo e kholo ea mmaraka. Joalo ka thepa e hlahang, zirconium tetrachloride e hloka ho bonts'a melemo e lekaneng ts'ebetsong le litšenyehelo ho fumana kananelo ea 'maraka.
Maikutlo a Bokamoso
Zirconium tetrachloride le lihlahisoa tsa eona li na le menyetla e pharaletseng ea tšebeliso ea libeteri tsa lithium. Ka tsoelopele e tsoelang pele ea thekenoloji, ts'ebetso ea tlhahiso ea eona e lebelletsoe ho ntlafatsoa le ho feta mme litšenyehelo li tla fokotseha butle-butle. Nakong e tlang, tetrachloride ea zirconium e lebelletsoe ho tlatselletsa lisebelisoa tse kang lithium iron phosphate le ternary lithium, esita le ho fihlela sebaka sa ho nkela sebaka maemong a itseng a ts'ebeliso.

ZrCl₄ e ntlafatsa ts'ebetso ea polokeho joang libetering?
1. Thibela lithium dendrite kgolo
Khōlo ea lithium dendrites ke e 'ngoe ea mabaka a bohlokoa a ho potoloha ha nako e khutšoanyane le ho baleha ha mocheso oa libeteri tsa lithium. Zirconium tetrachloride le lihlahisoa tsa eona li ka thibela ho thehoa le ho hōla ha lithium dendrites ka ho fetola thepa ea electrolyte. Ka mohlala, li-additives tse ling tse thehiloeng ho ZrCl₄ li ka etsa sekhahla se tsitsitseng sa li-interface ho thibela lithium dendrites hore li se ke tsa kenella ka electrolyte, kahoo li fokotsa kotsi ea potoloho e khutšoanyane.
2. Ntlafatsa botsitso ba mocheso oa electrolyte
Li-electrolyte tse tloaelehileng tsa metsi li na le tšekamelo ea ho bola ha mocheso o le holimo, li lokolla mocheso, ebe li baka ho baleha ha mocheso.Zirconium tetrachloride'me lihlahisoa tsa eona li ka sebelisana le likarolo tsa electrolyte ho ntlafatsa botsitso ba mocheso oa electrolyte. Electrolyte ena e ntlafetseng e thata ho feta ho bola ha mocheso o le holimo, kahoo e fokotsa likotsi tsa polokeho ea betri tlas'a maemo a phahameng a mocheso.
3. Ntlafatsa botsitso ba sebopeho
Zirconium tetrachloride e ka ntlafatsa botsitso ba sebopeho pakeng tsa electrode le electrolyte. Ka ho etsa filimi e sireletsang holim'a electrode, e ka fokotsa maikutlo a mahlakoreng pakeng tsa lisebelisoa tsa electrode le electrolyte, kahoo e ntlafatsa botsitso ba betri ka kakaretso. Ho tsitsa ha sebopeho sena ho bohlokoa ho thibela ho senyeha ha ts'ebetso le litaba tsa polokeho ea betri nakong ea ho tjhaja le ho tjhaja.
4. Fokotsa ho chesa ha electrolyte
Li-electrolyte tse tloaelehileng tsa mokelikeli hangata li tuka haholo, e leng se eketsang kotsi ea ho tuka ha betri tlas'a maemo a tlhekefetso. Zirconium tetrachloride le lintho tse tsoang ho eona li ka sebelisoa ho hlahisa li-electrolyte tse tiileng kapa li-electrolyte tse tiileng. Lisebelisoa tsena tsa electrolyte hangata li na le matla a tlase a ho cha, ka hona li fokotsa haholo kotsi ea ho chesa le ho phatloha ha betri.
5. Ntlafatsa bokhoni ba ho laola mocheso oa libeteri
Zirconium tetrachloride le lihlahisoa tsa eona li ka ntlafatsa bokhoni ba ho laola mocheso oa libeteri. Ka ho ntlafatsa conductivity ea mocheso le botsitso ba mocheso oa electrolyte, betri e ka senya mocheso ka katleho ha e matha ka meroalo e phahameng, kahoo e fokotsa monyetla oa ho baleha mocheso.
6. Thibela ho baleha ha mocheso oa lisebelisoa tse ntle tsa electrode
Maemong a mang, ho baleha ha mocheso oa lisebelisoa tse ntle tsa elektrode ke e 'ngoe ea lintlha tsa bohlokoa tse lebisang litabeng tsa polokeho ea betri. Zirconium tetrachloride le li-derivatives tsa eona li ka fokotsa kotsi ea ho baleha ha mocheso ka ho fetola lik'hemik'hale tsa electrolyte le ho fokotsa mokhoa oa ho bola oa thepa e ntle ea electrode mocheso o phahameng.
