Lithium-fluorocarbon battery (Li-(CFx)n) with cathode material of (CFx)n and anode material of lithium, which is the best Primary Battery system at present. The theoretical energy density of the Li-(CFx)n battery system is up to 2180Wh/kg, which is the battery system with the largest theoretical specific energy in the primary batteries. Lithium-fluorocarbon batteries consist of button, cylindrical and soft package batteries.
