Application of Foam Materials in Battery Electrode

Application of Foam Materials in Battery Electrode

Electrodes are conductors by which electrons flow through to generate a current. Large surface area, high electrical conductivity, and abundant channels have been recognized to be essential characteristics of the electrode materials. Thus, as with 3D-reticulate structure, high porosity, high specific surface area and uniform mass, foamed metals, alloys and conductive carbon materials are ideal options for battery electrodes.

The foam battery electrode is an electrode constructed with foam material to allow liquid to flow through the electrode; acting also as a filter. This battery foam technology is very exciting for the future of batteries.
