Battery having electrode with carbon current collector

摘要

The battery includes an electrode having an active medium on a current collector. The active medium includes one or more active materials. The current collector includes or consists of carbon nanotubes. The electrical conductivity and weight of carbon nanotubes permit the weight of the battery to be reduced while the energy density and the power density of the battery are increased.
