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.
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 .
This sets new industry records for single cell capacity and highest energy density for lithium batteries, Talent said in a statement. For comparison, Nio's (NYSE: NIO) 150-kWh semi-solid-state battery pack uses cells from Beijing WeLion New Energy Technology, with a capacity of 360 Wh/kg.
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.
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.
High-energy-density batteries are the eternal pursuit when casting a look back at history. 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 .
