Abstract
Examples are disclosed herein that relate to curved batteries. One example provides a battery comprising an anode arranged on an anode substrate, a cathode arranged on a cathode substrate, the anode substrate being curved at a first curvature and the cathode substrate being curved at a second curvature, and a separator between the anode and the cathode. A thickness of the anode substrate and a thickness of the cathode substrate are determined based on the curvature of the respective substrate, such that the one of the anode substrate and the cathode substrate with a larger curvature has a larger thickness.
