Nekukurumidza kusimudzira kweindasitiri yesimba idzva, kudiwa kwemabhatiri e-lithium ari kukura. Kunyangwe zvinhu zvakaita selithium iron phosphate (LFP) uye ternary lithium inotora chinzvimbo chikuru, nzvimbo yavo yekuvandudza simba remagetsi ishoma, uye chengetedzo yavo ichiri kuda kuvandudzwa. Munguva pfupi yapfuura, zirconium-based compounds, kunyanya zirconium tetrachloride (ZrCl₄) uye zvakabva pairi, zvishoma nezvishoma zvave kutsvaga hotspot nekuda kwekugona kwavo mukuvandudza hupenyu hwekutenderera uye kuchengetedzwa kwemabhatiri e lithium.
Zvinogona uye zvakanakira zirconium tetrachloride
Kushandiswa kwe zirconium tetrachloride uye zvinobva kwayo mumabhatiri e lithium kunonyanya kuratidzwa mune zvinotevera zvinhu:
1.Kuvandudza ion kutamisa kushanda zvakanaka:Zvidzidzo zvakaratidza kuti simbi organic framework (MOF) yekuwedzera ine yakaderera-yakarongeka Zr⁴⁺ masaiti anogona kuvandudza zvakanyanya kutamisa kushanda kwe lithium ions. Kudyidzana kwakasimba pakati penzvimbo dzeZr⁴⁺ uye lithium ion solvation sheath inogona kukurumidza kutama kwe lithium ions, nokudaro nekuvandudza chiyero chekuita uye kutenderera hupenyu hwebhatiri.
2.Enhanced interface kugadzikana:zirconium tetrachloride derivatives inogona kugadzirisa chimiro chekugadzirisa, kuwedzera kugadzikana kweiyo interface pakati pe electrode ne electrolyte, uye kuderedza kuitika kwekuita kwepadivi, nekudaro kunatsiridza kuchengetedzeka uye hupenyu hwesevhisi yebhatiri.
Kuenzana pakati pemutengo nekuita: Zvichienzaniswa nezvimwe zvinodhura zvakatsiga zvemagetsi emagetsi, iyo mbishi mutengo we zirconium tetrachloride uye zvinobva pairi wakadzikira. Semuenzaniso, mari yakasvibirira yemagetsi emagetsi akasimba akadai se lithium zirconium oxychloride (Li1.75ZrCl4.75O0.5) inongova $11.6/kg, iyo yakadzikira zvakanyanya pane zvechinyakare maelectrolyte akasimba.
Kuenzanisa ne lithium iron phosphate uye ternary lithium
Lithium iron phosphate (LFP) uye ternary lithium ndiyo yakajairika mabhatiri e lithium parizvino, asi imwe neimwe ine zvayakanakira nezvayakaipira. Lithium iron phosphate inozivikanwa nekuchengetedzwa kwayo kwepamusoro uye hupenyu hurefu hwekutenderera, asi simba rayo rakaderera; ternary lithium ine yakakwira simba density, asi kuchengetedzwa kwayo hakuna kusimba. Kusiyana neizvi, zirconium tetrachloride uye zvigadzirwa zvayo zvinoita zvakanaka mukuvandudza ion kutamisa kushanda zvakanaka uye kugadzikana kwechimiro, uye zvinotarisirwa kugadzirisa kukanganisa kwezvinhu zviripo.
Kutengesa zvipingamupinyi nematambudziko
Kunyangwe zirconium tetrachloride yakaratidza kugona kukuru mukutsvagisa marabhoritari, kushambadzira kwayo kuchiri kutarisana nemamwe matambudziko:
1.Kukura kwemaitiro:Parizvino, maitiro ekugadzirwa kwe zirconium tetrachloride uye zvigadzirwa zvayo hazvisati zvanyatsokura, uye kugadzikana uye kuwirirana kwekugadzirwa kwakakura kuchiri kuda kusimbiswa zvakare.
2.Cost control:Kunyangwe mutengo wezvigadzirwa wakaderera, mukugadzirwa chaiko, zvinhu zvinodhura senge synthesis process uye kudyara kwemidziyo zvinoda kutariswa.
Kugamuchirwa kwemusika: Lithium iron phosphate uye ternary lithium yakatotora chikamu chikuru chemusika. Sechinhu chiri kubuda, zirconium tetrachloride inoda kuratidza mabhenefiti akakwana mukuita uye mutengo kuti uwane kuzivikanwa kwemusika.
Ramangwana Outlook
Zirconium tetrachloride uye zvinobva mairi zvine tarisiro yakakura yekushandisa mumabhatiri e lithium. Nekuenderera mberi kwekufambira mberi kwetekinoroji, maitiro ayo ekugadzira anotarisirwa kuwedzeredzwa uye mutengo uchadzikira zvishoma nezvishoma. Mune ramangwana, zirconium tetrachloride inotarisirwa kubatanidza zvinhu zvakaita selithium iron phosphate uye ternary lithium, uye kunyange kuwana nzvimbo yekutsiva mune mamwe mamiriro ekushandisa.

ZrCl₄ inovandudza sei kuchengetedza kushanda mumabhatiri?
1. Inhibit lithium dendrite kukura
Kukura kwe lithium dendrites ndechimwe chezvikonzero zvakakosha zvekupfupika kwedunhu uye kupisa kunotiza kwe lithium mabhatiri. Zirconium tetrachloride uye zvigadzirwa zvayo zvinogona kudzivisa kuumbwa uye kukura kwe lithium dendrites nekugadzirisa zvinhu zve electrolyte. Semuenzaniso, zvimwe ZrCl₄-based additives inogona kuumba yakagadzikana interface layer kudzivirira lithium dendrites kubva pakupinda mu electrolyte, nekudaro kuderedza njodzi yekupfupika.
2. Kuwedzera kugadzikana kwekupisa kwe electrolyte
Maelectrolyte emvura echinyakare anowanzoora pakupisa kwakanyanya, achiburitsa kupisa, obva akonzera kutiza kwemafuta.Zirconium tetrachlorideuye zvigadzirwa zvayo zvinogona kuwirirana nezvikamu zviri mu electrolyte kuti uvandudze kugadzikana kwekupisa kwe electrolyte. Iyi electrolyte yakavandudzwa inonyanya kuoma kuora pakupisa kwakanyanya, nekudaro kuderedza njodzi dzekuchengetedza bhatiri pasi pemamiriro ekushisa kwakanyanya.
3. Kuvandudza interface kugadzikana
Zirconium tetrachloride inogona kuvandudza kugadzikana kwechimiro pakati pe electrode uye electrolyte. Nekugadzira firimu rekudzivirira pamusoro pe electrode, inogona kuderedza maitiro eparutivi pakati pezvinhu zve electrode uye electrolyte, zvichiita kuti iwedzere kugadzikana kwebhatiri. Iyi interface kugadzikana kwakakosha kudzivirira kukanganisa kwekuita uye kuchengetedza nyaya dzebhatiri panguva yekuchaja nekuburitsa.
4. Deredza kupisa kwe electrolyte
Maelectrolyte emvura echinyakare anowanzo kubvira zvakanyanya, izvo zvinowedzera njodzi yekutsva kwebhatiri pasi pemamiriro ekushungurudzwa. Zirconium tetrachloride uye zvinobva mairi zvinogona kushandiswa kugadzira maelectrolyte akasimba kana semi-solid electrolytes. Izvi zvinhu zve electrolyte zvinowanzove nekushomeka kwakadzikira, nekudaro zvichidzikisa zvakanyanya njodzi yekutsva kwebhatiri uye kuputika.
5. Kuvandudza kukwanisa kwekutonga kwekushisa kwemabhatiri
Zirconium tetrachloride uye zvinobva kwayo zvinogona kuvandudza kugona kwekupisa kwemabhatiri. Nokuvandudza kupisa kwemafuta uye kugadzikana kwekupisa kwe electrolyte, bhatiri rinogona kubvisa kupisa zvakanyanya kana richimhanya pamitoro yakakwirira, nokudaro kuderedza mukana wekupisa kwekupisa.
6. Kudzivirira kupisa kwekupisa kwezvinhu zvakanaka zve electrode
Mune zvimwe zviitiko, kupisa kwekutiza kwezvinhu zvakanaka electrode ndicho chimwe chezvinhu zvakakosha zvinotungamira kune bhatiri kuchengetedza nyaya. Zirconium tetrachloride uye zvinobva mairi zvinogona kuderedza njodzi yekupisa kwekupisa nekugadzirisa kemikari ye electrolyte uye kuderedza kuparara kwekuita kweiyo yakanaka electrode zvinhu pakupisa kwakanyanya.
