Innovative Material Concept for an Improved Silicon Anode

Graphic: Identifying isotope labeling in aged products with GC-MS The lithium-ion battery is currently state of the art, but has not yet realised its full potential. New electrode materials such as silicon instead of pure graphite in the anode offer a significantly increased electrochemical performance. Until now, this has been at the expense of the battery's lifespan. Silicon expands enormously during charge and discharge operation, not only taking up more space, but also significantly reducing the number of possible charge and discharge cycles. In order to counteract the change in volume, a team of scientists with the participation of the MEET Battery Research Center has developed an innovative material concept for a composite based on silicon and graphite for the anode. Strong cooperation for the sustainable battery of the future. "The battery of the future must combine all of these factors: higher energy density, a longer cycle life, maximum safety, improved sustainability and the lowest possible costs.
