We report a unique hierarchical Si hydrogel architecture with conductive polyaniline polymers connected on a sulfonated-graphene nanosheet, which gives high capacity, stable cycling performance of capacity with almost 100% Coulombic efficiency over 5000 cycles of Li-ion insertion/desertion especially at high current densities, and excellent rate reversibility.
