Battery and assembly method

摘要

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.

主权项

1. An apparatus, comprising:
a stack of battery electrodes, comprising:
a bipolar battery plate including:
an electrically conductive silicon wafer and an active material disposed on at least one surface of the silicon wafer to provide a first battery electrode; anda second battery electrode located on a surface of the electrically conductive silicon wafer opposite the first electrode; anda third battery electrode disposed in the stack and physically spaced apart from the second electrode; a housing, with the stack of battery electrodes disposed in the housing; and an electrolyte disposed in the housing such that a portion of the electrolyte in contact with the second and third battery electrodes is isolated from the first battery electrode at least in part by the electrically conductive silicon wafer; wherein the stack of battery electrodes is configured to establish a conduction path between the first and second battery electrodes through the conductive silicon wafer; and wherein a silicide is included on at least one surface of the conductive silicon wafer between the active material and the conductive silicon wafer.
