Electrodeposition as a Tool for 3D Microbattery Fabrication

3 volume scale, including all components and associated packaging. Moreover, miniaturized devices usually need the energy storage functions to be physically located on a small area—on a chip—making the energy and power density per footprint area a key factor for these batteries. The energy demand for these products is generally in the order of 1 J/(mm2 day), which conventional battery technologies fail to supply by an order of magnitude or more. Given the wide range of electrode chemistries available for lithium-ion batteries, these batteries are well-suited to be shaped into different complex 3D high-capacity architectures. This article focuses on the use of electrodeposition as a tool for manufacturing complex 3D battery architectures.
