Investigation on the Strategies for Discharge Capacity Improvement of Aprotic Li-CO 2 Batteries

To achieve a high-capacity battery, parameter sensitivity analysis is conducted. The initial porosity of the cathode is found to the most determining factor on the specific capacity. To this end, various cathode structures are designed and evaluated. Among these designs, the frustum conical porous cathode can lead to the largest capacity improvement of over 60%, demonstrating the feasibility of improving the capacity through structure design.
