Performant electrochemical storage devices appear as one of the solution to face the challenge of energy transition and development of carbon-less energy processes. In this context, lithium-ion batteries are a well-developed technology because of their lllgh energy density, their long life over cycling and their large field of applications, from microbatteries to stationary storage.
