プレゼンテーション概要

Silicon is a promising anode material that is widely investigated as a potential successor for graphite since it can store significantly more energy per mass and volume. Tremendous advancement towards commercialization of silicon anodes - including improving cycle life and minimizing electrode swelling - has been made over the past decade. Proper electrode engineering has brought silicon-based anode materials closer to commercialization into consumer applications. However, silicon technology has not yet been significantly commercialized due to a number of shortcomings. In particular, cycle life and irreversible capacity losses (ICL) due to side reactions continue to be issues that plague their widespread use.
 
Graphene, an atomically thin version of graphite widely regarded as a wonder material, has the potential to overcome many of the remaining issues due to graphene's unique combination of high surface area, high in-plane electrical conductivity, excellent tensile modulus and mechanical durability. Therefore, silicon-graphene composites have the ability to combine the high energy provided by silicon along with the high cycle life offered by graphene's unique properties. Indeed, properly designed composites can demonstrate significant increases of 10-30% energy density compared to commercial cells.
