A contact lens battery management system (BMS) monitors battery health in an electronic contact lens. A battery made with high-internal-resistance cells is coupled on a cell-by-cell basis to input switches of a power management integrated circuit (PMIC) that monitors, detects, and isolates faulty circuit components.

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.

A three-dimensional electrode array for use in electrochemical cells, fuel cells, capacitors, supercapacitors, flow batteries, metal-air batteries and semi-solid batteries.

A first separator (130) covers a first surface of a cathode electrode (110). The first separator (130) has a melting point of a first temperature. A second separator (140) covers a second surface of the cathode electrode (110). The second separator (140) has a melting point of a second temperature higher than the first temperature. An adhesive layer (132) is formed by melting a portion of the first separator (130). The adhesive layer (132) pastes the first separator (130) and the second separator (140) to each other.
