During the past decade, lithium-ion batteries improved significantly in terms of volumetric energy density, which describes the amount of energy that can be contained within a given volume. The higher the volumetric energy density is, the smaller the battery pack can be (assuming the same energy content).
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.
The devices boast a gravimetric energy density of 711.3 Wh/kg and a volumetric energy density of 1653.65 Wh/L, both of which are the highest in rechargeable lithium batteries based on an intercalation-type cathode, Li tells Physics World.
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.
Recently, according to reports, Amprius announced that it has produced the first batch of ultra-high energy density lithium-ion batteries with silicon based negative electrode, which have achieved major breakthroughs in specific energy and energy density, and the energy density of the lithium battery reached 450 Wh kg −1 (1150 Wh L −1).
Among the above cathode materials, the sulfur-based cathode material can raise the energy density of lithium-ion battery to a new level, which is the most promising cathode material for the development of high-energy density lithium batteries in addition to high-voltage lithium cobaltate and high‑nickel cathode materials. 7.2.
