Advantages of solid state batteries

In solid state batteries, the liquid electrolyte that is usually used in conventional batteries is replaced by an ion conducting solid. Since the electrodes and other components of a battery are usually also solid, these batteries are called "solid state batteries".

Solid state batteries offer many advantages: They cannot leak, are generally less toxic, and in case of failure, the components generally cannot burn or explode. Most importantly, solid electrolytes allow the use of electrode materials with voltages in excess of 5 volts because of their wider electrochemical window as well as the use of lithium metal as anode because of their chemical compatibility with lithium. All of these advantages mean an increase in energy density while maintaining the inherent safety of the battery.
