Abstract

Embodiments described herein relate generally to electrodes for electrochemical cells, the electrodes including an electrode material disposed on a current collector. In some embodiments, an electrode includes an edge protection barrier member on a perimeter of a surface of the current collector. The barrier member forms a wall along the main edge(s) of the current collector, defining an inner region bounded by the barrier member and the top surface of the current collector, and the electrode material occupies the inner region.
