Components, Assembly and Electrochemical Properties of Three-Dimensional Battery Architectures

Abstract

In this research program, we advanced 3-D battery technology through a combination of battery design, component development, and improved understanding of electrochemical properties. Our research on liquid polysulfide catholytes emphasized high concentration systems and wider operating potential regimes in order to increase energy density. We also prepared inorganic gels consisting of nanoscale silica networks that have lithium polysulfide catholyte filling the pores. Another key result was the fabrication of a cathode into a 3-D structure which is compatible with the silicon/SU-8 fabrication process. Finally, we assembled a full 3-D battery device and demonstrated charge and discharge cycling in the prototype.
