The United States Advanced Battery Consortium ( @USABC ) has awarded a $4-million contract to @SiNodeSystems for the development of advanced anode materials for automotive lithium-ion batteries. The 30-month program will focus on the development of silicon-graphene anode material for vehicle applications, and the development and scale-up of pouch cells. #SiNode ’s technology uses a composite of silicon and graphene in a layered structure designed to overcome technical hurdles to silicon anodes such as volumetric expansion and unstable SEI that leads to poor cycle life. The SiNode materials architecture disperses silicon nanoparticles within a flexible 3D #graphene network that stabilizes the Si active material during charge and discharge, leading to minimal volume change during cycling. The graphene also offers enhanced electronic conductivity.
