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.
At present, the publicly reported highest energy density of lithium-ion batteries (lithium-ion batteries in the traditional sense) based on embedded reactive positive materials is the anode-free soft-pack battery developed by Professor Jeff Dahn's research team (575 Wh kg −1, 1414 Wh L −1) .
Furthermore, the development of high energy density lithium batteries can improve the balanced supply of intermittent, fluctuating, and uncertain renewable clean energy such as tidal energy, solar energy, and wind energy.
The theoretical energy density of lithium-ion batteries can be estimated by the specific capacity of the cathode and anode materials and the working voltage. Therefore, to improve energy density of LIBs can increase the operating voltage and the specific capacity. Another two limitations are relatively slow charging speed and safety issue.
In order to achieve high energy density batteries, researchers have tried to develop electrode materials with higher energy density or modify existing electrode materials, improve the design of lithium batteries and develop new electrochemical energy systems, such as lithium air, lithium sulfur batteries, etc.
Among various rechargeable batteries, lithium-ion batteries have an energy density that is 2–4 times higher than other batteries such as lead-acid batteries, nickel‑cadmium batteries, and nickel-metal hydride batteries, demonstrating a significant advantage in energy density [, , ].
