Lithium hexafluorophosphate CAS:21324-40-3

Lithium hexafluorophosphate imagwira ntchito yofunika kwambiri muukadaulo wa batri ya lithiamu-ion yomwe ingadzazidwenso, komwe imagwira ntchito ngati gawo lofunikira la electrolyte. Mwa kusungunuka mu organic solvents, LiPF6 imapereka lithiamu cations ndi hexafluorophosphate anions zomwe zimathandiza kuyendetsa bwino kwa ionic mkati mwa dongosolo la batri. Izi zimalimbikitsa kuyenda kwa ma lithiamu ion pakati pa anode ndi cathode panthawi yamayendedwe ochapira ndi kutulutsa, zomwe zimathandiza kuyenda kwa magetsi ndikuthandizira magwiridwe antchito onse a batri. Kugwiritsa ntchito LiPF6 ngati mchere wa electrolyte kumawonjezera kuchuluka kwa mphamvu, kukhazikika kwa voltage, komanso kuyendetsa bwino mabatire a lithiamu-ion, zomwe zimapangitsa kuti ikhale yothandiza kwambiri pakugwiritsa ntchito zida zamagetsi zonyamulika, magalimoto amagetsi, ndi makina osungira mphamvu osasuntha. Kuphatikiza apo, lithiamu hexafluorophosphate imalola kupanga mabatire a lithiamu-ion ogwira ntchito kwambiri okhala ndi chitetezo chabwino komanso kukhazikika kwa kutentha. Kugwirizana kwake ndi zipangizo zosiyanasiyana za electrode ndi mapangidwe a electrolyte kumathandizira kupititsa patsogolo ukadaulo wa batri wa m'badwo wotsatira, kuphatikiza mabatire olimba ndi lithiamu-sulfur. Kuphatikiza apo, mankhwalawa amagwiritsidwa ntchito popanga ma electrolyte apadera pazinthu zapadera monga ndege, zida zamankhwala, ndi malo osungira mphamvu, komwe zofunikira zogwirira ntchito ndizofunikira. Ponseponse, lithiamu hexafluorophosphate ndi chinthu chofunikira kwambiri chomwe chimapangitsa ukadaulo wa batri ya lithiamu-ion, zomwe zimapangitsa kupita patsogolo pakusunga mphamvu ndi kuyika magetsi m'magawo osiyanasiyana.
