Abstract. Graphite-like coated silicon (Si@G) material has been shown to be only partly useful in addressing the technological problems of high-capacity Si anodes in lithium ion batteries (LIBs). This is because of inevitable and large internal stresses in a Si@G structure induced by instantaneously explosive expansion of Si upon lithiation
