liquids exhibit excellent hydrolytic stability, low viscosity and high electrochemical and thermal stability. Organic and inorganic salts with FAP anions possess high electrochemical stability and conductivity that makes them attractive for application in several electrochemical devices (Li-ion batteries, super-capacitors, etc.). The possible application of H[(RF)3PF3] (HFAP), (RF)2P(O)(OH) and (RF)P(O)(OH)2
电化学氟化(Simons工艺)为一系列三(全氟烷基)二氟磷烷提供了廉价的商业途径。这些物质是制备各种含氟化合物的方便原料。描述了用全氟烷基氟磷酸盐(FAP)和全氟烷基次膦酸酯阴离子合成新的导电盐和离子液体的方法。FAP离子液体具有出色的水解稳定性,低粘度以及高电化学和热稳定性。具有FAP阴离子的有机盐和无机盐具有很高的电化学稳定性和电导率,这使其在多种电化学设备(锂离子电池,超级电容器等)中具有吸引力。H [(R F)3 PF 3的可能应用讨论了作为质子传导膜的成分的(HFAP),(R F)2 P(O)(OH)和(R F)P(O)(OH)2。
