In order to improve lithium-ion batteries, researchers at our laboratory are replacing the graphite of the negative electrode with silicon-based materials that can store much more lithium. These new nano-architected composite materials are made up of active domains of Si-amorphous and crystalline FeSi2 nanoparticles dispersed in a graphite matrix. They are studying the ageing phenomenon of these anodes capable of withstanding 700 cycles with a capacity of nearly 70%
