Abstract
This invention provides an electrode comprising a porous conductive substrate as well as an electrode active material and a conductive auxiliary filled in the pores in the substrate. This electrode exhibits improved shape stability (strength), a lower resistivity and better response. This electrode can be used to provide an electrochemical cell capable of quick charge/discharge and exhibiting improved cycle properties.
