THREE DIMENSIONAL ELECTRODE HAVING ELECTRON DIRECTING MEMBERS AND METHOD OF MAKING THE SAME

摘要

A battery has a three dimensional electrode including a current collector, electron directing members, each electron directing member having a perimeter edge attached to a surface of the current collector with a polymer binder, the electron directing members extending from the surface of the current collector and configured to direct electron flow along a layered direction of the electrode, an active material layer on the current collector and a separator. The electron directing members extend into the active material layer and having a free end in spaced relation to the separator.
