Scientists in China and the US say a new anode material they have created represents a significant step forward in the development of long-life stationary lithium-ion batteries for large-scale energy storage systems.
Lithium-ion batteries are one of the most effective rechargeable batteries thanks to their high energy density and low environmental impact. However, the performance of current lithium-ion batteries, which use graphite as the anode material, cannot satisfy requirements of large-scale systems that could support smart electricity grids linked with renewable sources. Their charging rate is limited because at voltages required for a fast charge, lithium deposition, or plating, occurs, which can result in the battery short circuiting.
