Lattice for a battery electrode substrate.

摘要

An improved substrate (30) for a battery electrode is disclosed. The substrate is in the form of a reticulated lattice bordered by a current conducting perimeter (31) and having a current connection or tab (32) on the perimeter. The lattice is comprised of first current carrying portions (35) which converge toward an imaginary point outside the perimeter of the substrate, which point can lie on an imaginary bisector to the lattice. Second current carrying portions (38) intersect the first current carrying portions (35) and extend generally perpendicularly to them at the points of intersection. The lattice thus formed improves the current density of the electrode and provides for a more uniform current distribution, serves to focus currentflow in the direction of the conducting tab, and mechanically strengthens the tab connection to the substrate.
