Abstract
A carbon fiber material is substantially constituted by fiber agglomerates, having agglomerate sizes in a range of not less than 5 .mu.m and not more than 500 .mu.m, formed by vapor grown carbon fibers having a diameter of not less than 0.05 .mu.m and not more than 5 .mu.m, having a microstructure such that some fiber contact points are bonded together with substances produced by carbonizing carbonaceous matters. This carbon fiber material is used as a filler material to various matrices, and used also as an electrode material for making electrodes in batteries, especially in electric double-layer capacitors, and in secondary batteries, especially those based on lithium or lead.
