Abstract
An example includes a method including forming a battery electrode by disposing an active material coating onto a silicon substrate, assembling the battery electrode into a stack of battery electrodes, the battery electrode separated from other battery electrodes by a separator, disposing the stack in a housing, filling the interior space with electrolyte, and sealing the housing to resist the flow of electrolyte from the interior space.
