The copper foam is approximately 98% air, or void space. Through Prieto Battery’s proprietary technology the anode and separator material are applied via electrodeposition. Then the cathode material is applied as a liquid slurry. Due to an increase in surface area of approximately 60X for lithium-ion diffusion, Prieto’s foam battery is expected to have power densities reaching 14,000 W/L while maintaining energy densities of 650 Wh/L. The foam battery will be customizable, capable of being optimized for either power density or energy density." Looks like an explosive potential! ;-) T
