Title:
INSOLUBLE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2006/073163
Kind Code:
A1
Abstract:
An insoluble electrode that even when used in regions of intense consumption such as one where the phenomenon of conversion to negative electrode occurs, can stably maintain positive electrode functions for a prolonged period of time, and that can minimize the amount of electrode active material used, ensuring long operating life and economic advantage. For realizing this, porous layer (20) of spherical titanium powder sintered is provided as a foundation layer on a surface of metal base material (10) of titanium plate. Electrode active material layer (30) is formed across the surface through interior of the porous layer (20). Portion of the electrode active material penetrates the porous layer (20), resulting in realization of a strong anchor effect not comparable to that exhibited at blast processing. Even if portions exposed from the porous layer (20) are detached or caused to fall, the positive electrode functions can be maintained by the electrode active material remaining in the porous layer (20).
