Micro-battery, energy density
Micro-batteries could be used to power a wide variety of small system.
Current battery has low energy density and big volume.
This invention is founded on a micro-fabricated structure of 3D electrode array, proposing an integrally packaged, solid-state lithium rechargeable microbattery with a 3-dimensional interpenetrating-electrode internal architecture. The microbatteries will have the capability for outer package aspect ratios of less than 5:1 for maximum to minimum dimensions, active materials packing fraction of >75% in a 1mm3 volume. The proposed approach will use currently available and proven cathode and anode materials, but will allow drop-in of higher energy or higher rate active materials as they are developed in the future.
This invention proposes to achieve the energy densities of 350-1500Wh/L.
