Power density of spinel cathode secondary lithium-ion batteries

Several commonly used representations of power densities and their shortcomings for describing the high-power, short-pulse regime are discussed. The Specific Power Profile (SPP) is presented as an informative and well-defined power density representation. The power densities of Mn-based and Co-based Li-ion (commercially available MOLICEL), nickel cadmium, and nickel metal hydride cells are compared using the SPP.
