Theoretical gravimetric capacity
WebbThe gravimetric capacity of the former was only 15 mAh/g. The material obtained by the sol–gel method was made up of smaller crystalline grains and had a porous structure, which led to an increase in capacity to 50 mAh/g. Difficulty in achieving the theoretical value (170 mAh/g) was mainly attributed to poor electronic conductivity . Webb9 juli 2024 · Electrodes, Oxides Abstract Lithium sulfur (Li-S) batteries with high theoretical energy density (∼2.5 kWh kg –1) and high theoretical gravimetric capacity (1672 mAh g –1) have drawn great attention as they are promising candidates for large-scale energy storage devices.
