Theoretical energy density above 1000 Wh kg −1 /800 Wh L −1 and electromotive force over 1.5 V are taken as the screening criteria to reveal significant battery systems for the next-generation energy storage. Practical energy densities of the cells are estimated using a solid-state pouch cell with electrolyte of PEO/LiTFSI.
The gravimetric energy density of a battery can be S Mis the sum of the formula mole weights of the two reactants. is the sum of the formula mole volume of the two reactants. ). reactant are known. These values can be found in the thermo- dynamic data handbook.
Energy density of batteries experienced significant boost thanks to the successful commercialization of lithium-ion batteries (LIB) in the 1990s. Energy densities of LIB increase at a rate less than 3% in the last 25 years . Practically, the energy densities of 240–250 Wh kg −1 and 550-600 Wh L −1 have been achieved for power batteries.
The electrode material determines the volume energy density of the battery, so the volume energy density of the battery is forced to increase under the condition that the battery material system and volume are unchanged, which is bound to use thinner separator materials [, , ].
Among all calculated systems, the Li/F2 battery processes the highest energy density and the Li/O2 battery ranks as the second highest, theoretically about ten times higher than current Li-ion batteries.
Strategies such as improving the active material of the cathode, improving the specific capacity of the cathode/anode material, developing lithium metal anode/anode-free lithium batteries, using solid-state electrolytes and developing new energy storage systems have been used in the research of improving the energy density of lithium batteries.
