Abstract
This disclosure provides collector plates for an energy storage device, energy storage devices with a collector plate, and methods for manufacturing the same. In one aspect, a collector plate includes a body. One or more apertures extend into the body. The apertures are configured to allow a portion of a free end of a spirally wound current collector of a spirally wound electrode for an energy storage device to extend into the one or more apertures.
Claims26
An energy storage device, comprising:
- an electrode comprising a current collector, the current collector comprising a plurality of laterally spaced layers forming a free end;
- a container configured to receive the electrode and an electrolyte;
- and
- a collector plate comprising a body with two or more apertures, a first support member extending between two adjacent apertures of the two or more apertures, and a second support member extending around the two or more apertures and the first support member, the two or more apertures extending into a lower surface of the body, and configured to provide flow through the body, wherein a first portion of the free end of the current collector extends into the two or more apertures when the current collector is pressed against the collector plate.
