The classic example of a good military-only battery would be those using molten salts as an electrolyte (typically at 150-500 ºC) [1]. Very high energy density

The classic example of a good military-only battery would be those using molten salts as an electrolyte (typically at 150-500 ºC) [1]. Very high energy density (around 74 Ahr/kg [2] compared to LiPo's ~50 Ahr/kg [3]) and very high power density. Not finger friendly.
