Improvements in materials – whether for existing lithium NMC graphite cells, silicon anodes or lithium-metal solid state cells – can improve output, but the cell format, whether cylindrical or a mix of prismatic and pouch, can reduce wasted space and increase energy density. Then, cell-to-pack and other topologies can further reduce the passive elements in the system.
