No published manufacturing models compare cylindrical to prismatic li-ion cell cost. We present a process based cost model for specified cylindrical cell dimensions. Economies of scale already reached in cylindrical cell manufacturing. Larger cells or cells with thicker electrodes offer a lower cost per kWh. Prismatic cells, which can be larger, offer more opportunity for cost reduction.
