The internal resistance of the electrodes influence the discharge capacity. As the electrode geometry influences its resistance, topology optimization can be applied to determine the electrode shape such that it has a minimal internal resistance and thus obtain the maximum discharge performance. The influences of different design parameters have been analysed by means of numerical case studies. Several penalty techniques have been used to make the final topology more realistic and easy to manufacture. The discharge capacity and capacity fade under different discharge current, different design structures and different optimization constraints are imposed and analysed. A three dimensional electrode model based on the topology optimization is built and simulated. The comparison between different optimization methods has been studied.
