Abstract
The metal clad fiber woven cloth consists of non-metal fiber woven cloth as base material and metal coating cladding the non-metal base cloth. The metal coating includes the electric deposited layer on the non-metal fiber cloth base and conducting film between the non-metal fiber cloth base and the electric deposited layer. The fiber cloth base is first surface treated to obtain excellent surface conductivity, and metal material with high conductivity and high corrosion resistance is deposited electrically to the surface of the base to form compact cladding metal layer. The base material and the cladding metal layer are made to combine firmly into one integral with high mechanical strength, high conductivity and high corrosion resistance. The metal clad fiber woven cloth may be further processed into electrode or electrode material for high power, high specific energy and long service life accumulator.
Description
Technical field:
