Na-ion batteries are emerging as potential alternatives to existing lithium based battery technologies. In theory, the maximum achievable specific energy densities of sodium-ion batteries (SIBs) are, due to the higher mass and larger ionic radius of Na+ compared to Li+, expected to be slightly. Based on the energy capacity (1 kW h of storage capacity), and with an assumed cycle life of 2000 cycles, the assessed SIB shows promising results already at the lower end of those of.
