Rapid Li+ pseudocapacitance observed for the first time in an amorphous material.
Amorphous FePO4 thin film electrodes behave as pseudocapacitors.
Specific power of 1 MW kg−1 obtained in addition to excellent cycling performance.
Self-enhancing kinetics resulted in 50% increased specific capacity during cycling.
