Abstract (en)

[origin: WO0055931A1] Surfaces suited to performing chemical reactions thereon are provided by a sponge material (16) having fine dendrites (18). The sponge material may be formed by growing the dendrites on a substrate (14) or particles of the sponge material may be sintered onto a substrate. The sponge material is suitable for use as an anode (10) or a cathode (12) in a battery (1). The sponge material may be coated with another material, which acts as a catalyst, or which improves the electrical conductivity of the sponge.
