Abstract
Components for use in electrochemical double-layer capacitors utilize at least one layer of a flexible graphite sheet material in an electrode or current collector or utilize a tanged metal layer in a current collector.
Claims26
An electrochemical double-layer capacitor comprising:
- two paired electrodes wetted with an electrolyte, each electrode being in contact with a current collector comprised of flexible graphite sheet and being separated from the other of the paired electrodes by a separator layer porous to the electrolyte.
An electrochemical double-layer capacitor comprising:
- two paired electrodes comprising graphite, both wetted with an electrolyte, each electrode being in contact with a current collector comprising tanged metal and being separated from the other of the paired electrodes by a separator layer porous to the electrolyte.
