This pioneering battery exhibited higher energy density value up to 130 Wh kg −1 (gravimetric) and 280 Wh L −1 (volumetric). The Table 1 illustrates the energy densities of initial rechargeable LIBs introduced commercially, accompanied by the respective company names .
This is the calculation formula of energy density of lithium secondary batteries: Energy density (Wh kg −1) = Q × V M. Where M is the total mass of the battery, V is the working voltage of the positive electrode material, and Q is the capacity of the battery.
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 .
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.
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) .
The theoretical specific capacity of the lithium metal anode (3860 mAh g −1) is close to ten times that of the graphite anode (372 mAh g −1), so lithium metal batteries are able to significantly increase the energy density of the battery [18, 76].
