KVOPO4 as Cathode for Sodium Ion Batteries
A new material (i.e. KVOPO4) was synthesized and performed as a cathode for sodium ion batteries. It is a multi-electron cathode which can store more than one sodium ion during a single charge/discharge process. The multi-electron feature makes KVOPO4 a high energy density sodium ion battery cathode, which could be applied in a wide battery market, such as being used in electrical vehicles, portable electronics, grid application, etc.
The advantage of KVOPO4 over the other competitive cathodes should be the higher energy density (both gravimetric and volumetric) and better safety, which is the most important two factors for today’s Li/Na ion battery products.
