Abstract
A current collector for use in a battery wherein the current collector is coaxial with the battery axis and is fabricated with a plurality of pairs of layers of electrically conducting material with alternate layers having different conductivities. An anisotropic resistivity structure is thus formed having a greater resistance in the axial direction than in a radial direction relative to the axis so as to provide for a more uniform current distribution.
