Liquid Battery Offers Safer, More Effective Energy Storage

Jan-23-16 Researchers have created a safe and efficient liquid battery that could have applications in long term energy storage.

Created by a team in Shanghai, the battery features a water soluble cathode made of iodide and triiodide ions that has been dissolved in a watery electrolyte containing either sulfur or lithium ions. The anode, made of polyimide, is separated from the cathode by a polymer membrane. During charging, the iodide forms triiodide, and the lithium or sodium ions move through the membrane to react with the polyimide. The process reverses while the electricity is being discharged by the battery.

Not only is the amount of metal used in the battery reduced, the battery also has a life of up to 50,000 cycles, and can be charged or discharged in just over six seconds—offering a power level that is close to that of supercapacitors.
