摘要：A porous electrode for electrochemical cells, methods of making the same andits application are described. The porous electrode is comprised of a porous conductivelayer and an insulating layer, whereas the pores inside the conductive layer function asmini-containers for the active metal for rechargeable batteries, and the insulatingmaterial covers the top conductive surface of the conductive layer and blocks the siteswhere active metal dendrite would otherwise preferentially grow. An example of suchelectrodes is a porous copper foil with top surface coated with polyvinylene difluoride(PVDF). Electrochemical cells containing the invented electrode, such as rechargeablelithium batteries, sodium batteries and aluminum batteries, have good cycle life andsafety performance.
