ABSTRACT:
Cathode collectors are made in a substantially dry method from carbon fibrils that have a fiber diameter of from about 2 to about 200 nanometers, a fiber length to diameter ratio of from about 10 to about 500, with a maximum length of 1 millimeter, and a fiber surface area of from about 10 to about 500 m.sup.2 /g, and a binder.
