Lithium hexafluorophosphate CAS: 21324-40-3

Lithium hexafluorophosphate ua lub luag haujlwm tseem ceeb hauv kev siv roj teeb lithium-ion uas rov qab tau, qhov chaw uas nws ua haujlwm ua ib qho khoom siv electrolyte uas tsis tuaj yeem tsis tau. Los ntawm kev yaj hauv cov kuab tshuaj organic, LiPF6 muab cov lithium cations thiab hexafluorophosphate anions uas ua rau muaj kev sib txuas lus ionic hauv lub roj teeb. Qhov no txhawb kev txav mus los ntawm lithium ions ntawm anode thiab cathode thaum lub sijhawm them thiab tso tawm, pab txhawb kev ntws ntawm cov hluav taws xob thiab pab txhawb rau lub roj teeb kev ua haujlwm tag nrho. Kev siv LiPF6 ua cov ntsev electrolyte ua rau lub zog ceev, kev ruaj khov ntawm voltage, thiab kev ua haujlwm ntawm cov roj teeb lithium-ion ua rau nws muaj txiaj ntsig zoo rau kev siv cov khoom siv hluav taws xob, tsheb fais fab, thiab cov tshuab khaws cia hluav taws xob. Tsis tas li ntawd, lithium hexafluorophosphate ua rau muaj kev tsim cov roj teeb lithium-ion ua haujlwm siab nrog kev nyab xeeb zoo dua thiab kev ruaj khov thermal. Nws qhov sib xws nrog ntau yam khoom siv electrode thiab cov qauv electrolyte txhawb kev nce qib ntawm cov thev naus laus zis roj teeb tiam tom ntej, suav nrog cov roj teeb solid-state thiab lithium-sulfur. Tsis tas li ntawd, cov tshuaj no pom daim ntawv thov hauv kev tsim cov electrolytes tshwj xeeb rau cov ntawv thov niche xws li aerospace, cov khoom siv kho mob, thiab kev khaws cia hluav taws xob grid, qhov twg cov kev cai ua haujlwm nruj yog qhov tseem ceeb. Zuag qhia tag nrho, lithium hexafluorophosphate sawv cev rau qhov tseem ceeb ntawm kev siv roj teeb lithium-ion, tsav kev nce qib hauv kev khaws cia lub zog thiab kev siv hluav taws xob thoob plaws ntau yam kev lag luam.
