PILE STRUCTURE AND METHOD OF MAKING SAME

摘要

Pile structure for use in batteries, particularly seawater batteries. The pile structure comprises one or more plates (2) which are separated by separator plugs (3) which extend via through-holes (5) from surface to surface of each plate. The separator plugs (3) are formed to integral spacer heads (33) beyond one surface of each plate. A continuous or intermittent band (30) is formed around the edge of each plate, and is provided with projections (36) which extend beyond that one surface of each plate, coextensively with the spacer heads. The separator plugs (33) and bands (30) may be formed by injection moulding process. The openings between the projections (36) permit passage of seawater. Another application for the pile structure is as a heat exchanger.
