Abstract
A process for making an electrode for an electrochemical cell includes loading a porous metal support with an active material, placing a porous metal electrical connector on the loaded support, and compressing the connector and the loaded support together such that the connector and support interpenetrate each other. The resulting electrode comprises a porous support which is loaded with active material and incorporates an electrical connector displaying a structure similar to that of the support. The three-dimensional structures of the porous materials of the support and of the connector have interpenetrated and bonded through compression.
