Although lithium ion batteries can provide higher energy density (W h/kg) than other secondary systems, they have limited power density (W/kg) compared to double layer and pseudocapacitors. Hence the improvement of the specific power density in lithium ion batteries is a fundamental issue to develop better HEVs and EVs.
