Researchers from the Martin group in Materials Science and Engineering have developed a new approach to improve the capacitive energy storage density of materials. Capacitors that rapidly store and release electric energy are key components in modern electronics and power systems. However, the most commonly used ones have low energy densities compared to other storage systems like batteries or fuel cells, which in turn cannot discharge and recharge rapidly without sustaining damage. The research illustrates a process whereby the team can greatly improve the material performance parameters essential to achieving large energy storage densities.
