Developments towards high energy density Li-batteries: new sulfide rocksalt cathode materials and improvement of lithium metal anode
Résumé
Li-Ion batteries are the technology of choice for most of today’s applications, especially those demanding
high energy densities. Large part of this success is due to intercalation electrodes, like graphite in the
negative electrode and lamellar oxides in the positive electrode, which constitute a limit in term of energy
density and power. Renewable energy and especially electric mobility demand a considerably higher
energy density, which is unlikely to be met with the current technology. Therefore, investigating new
materials to overcome these limits is fundamental. In this presentation, both cathode and anode
developments will be considered.
