Based on the prototype design of high-energy-density lithium batteries, it is shown that energy densities of different classes up to 1000 Wh/kg can be realized, where lithium-rich layered oxides (LLOs) and solid-state electrolytes play central roles to gain high energy densities above 500 Wh/kg.
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.
In the laboratory or in the upstream area of battery manufacturing, it is often the case that the performance obtained from coin cells tested in the laboratory is used to estimate the energy density of lithium batteries. The exact energy densities of lithium batteries should be obtained based on pouch cells or even larger batteries.
To obtain lithium-ion batteries with a high power density, the cathode materials should possess high voltage and high electronic/ionic conductivity, which can be realized by selecting high-voltage materials and modifying them to improve the voltage and reduce the battery’s internal resistance.
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) .
Typically expressed in watt-hours per liter (Wh/L) or kilogram (Wh/kg), it determines the power a battery can hold and subsequently deliver. High energy density signifies more incredible energy stored within a compact space or lighter weight, translating to longer-lasting, more powerful, and efficient batteries.
