GHGT-9 Phosphate Materials for Lithium Batteries and Energy Storage

The trend to electrification in our societies calls for other sources of energy and storage than carbon materials, especially fossil ones. Lithium batteries have emerged in the last decades as a convenient way to store and deliver the most noble and versatile form of energy: electricity. From cell phones and other portable applications, the technology is now growing fast as a vector to store energy for transportation and use on the grid. Lithium's light weight, its reactivity to form Li2O and its small ionic radius have led to the development of Li-insertion oxide structures that can act as electrode materials or electrolytes. Phosphate materials have recently been discovered that can make new stable complex oxide structures allowing the design of safer, performing and economically viable large–scale storage batteries, C-LiFePO4 being the most successful one to date.
