Batteries and supercapacitors serve as the basis for electrochemical energy-storage devices. Although both rely on electrochemical processes, their charge-storage mechanisms are dissimilar, giving rise to different energy and power densities. Pseudocapac
A high-efficiency, high-power-density buffer architecture is proposed for power pulsation decoupling in power conversion between dc and single-phase ac. We present an active decoupling solution that yields improved efficiency and reduced circuit complexity compared to existing solutions. In the proposed...

the cell may need to be large if the power density is low. Power density (i.e., electrical energy per unit area of fuel cell MEA) depends greatly upon cell architecture and polarization losses within the cell. Indeed, the design of efficient cells with high power density is the subject ...
Commercial lithium ion cells are now optimised for either high energy density or high power density. There is a trade off in cell design between the power and energy requirements. A tear down protocol has been developed, to investigate the internal components and cell engineering of nine cylindric...
There is ever increasing demand of advanced battery technologies with high safety and low cost for applications in portable electronics, electrified vehicles, and renewable energy storage1,2,3,4,5,6,7. Although lithium-ion batteries have gained great improvement in energy/power density and life spa...
