Given the high energy density of gasoline, the exploration of alternative media to store the energy of powering a car, such as hydrogen or battery, is strongly limited by the energy density of the alternative medium.

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.

The toolkit is flexible enough to assist the battery community in quantifying the impact of materials chemistry and fractions, electrode thicknesses and loadings, and electron flows on cell energy density and costs and in utilizing inverse engineering concepts to correlate the cell energy density output to materials and cell design inputs.
The main focus of energy storage research is to develop new technologies that may fundamentally alter how we store and consume energy while also enhancing the performance, security, and endurance of current energy storage technologies. For this reason, energy density has recently received a lot of attention in battery research.
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.
Higher energy density batteries can store more energy in a smaller volume, which makes them lighter and more portable. For instance, lithium-ion batteries are appropriate for a wide range of applications such as electric vehicles, where size and weight are critical factors .
Consequently, the energy density metrics reported for SSBs fall quite short of the conventional Li-ion batteries that exceed 250 Wh kg −1 at the cell level. 17 Enabling a SSB technology requires a careful examination of ongoing research and development (R&D) approaches to guide future cell development toward practical applications.
