A closer look at Prieto Battery innovation: Foam technology.
Prieto’s first battery to market will be produced with a copper foam substrate. 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.
While the basic science is the same, the specific technology used comes down to the application. Foam will be an ideal application for Prieto Battery’s first product introduction into E-bikes, and other portable electronic devices such as smartphones.
Foam technology and nanowires – better technology, better batteries.
