The rechargeable battery systems with lithium anodes offer the most promising theoretical energy density due to the relatively small elemental weight and the larger Gibbs free energy, such as Li–S (2654 Wh kg −1), Li–O 2 (5216.9 Wh kg −1), Li–V 2 O 5 (1532.6 Wh kg −1), Li–FeF 3 (1644 Wh kg −1), etc.
A high-power battery, for example, can be discharged in just a few minutes compared to a high-energy battery that discharges in hours.

With an energy density range of 30 to 50 Wh/kg, lead-acid batteries lag behind lithium-ion batteries'' energy density range of 50 to 260 Wh/kg. Moreover, lithium-ion batteries consist of smaller cell types with different energy ranges and thus they are thermally more stable.
1 Introduction. Following the commercial launch of lithium-ion batteries (LIBs) in the 1990s, the batteries based on lithium (Li)-ion intercalation chemistry have dominated the market owing to their relatively high energy density, excellent power performance, and a decent cycle life, all of which have played a key role for the rise of electric vehicles (EVs).

The energy density of lithium-ion batteries can vary with the state of charge and the number of charge-discharge cycles. Cycling behavior, including depth of discharge and charging rates, can affect the degradation of active materials, impacting energy density over the battery''s lifespan.
At present, the energy density of the mainstream lithium iron phosphate battery and ternary lithium battery is between 200 and 300 Wh kg −1 or even <200 Wh kg −1, which can hardly meet the continuous requirements of electronic products and large mobile electrical equipment for small size, light weight and large capacity of the battery order to achieve high
However, the current energy densities of commercial LIBs are still not sufficient to support the above technologies. For example, the power lithium batteries with an energy density between 300 and 400 Wh/kg can accommodate merely 1–7-seat aircraft for short durations, which are exclusively suitable for brief urban transportation routes as short as tens of minutes [6, 12].
