Abstract

High energy capacity Li-ion batteries using Si film anodes are found to have a long cyclic life by successful relaxation of the stress induced during lithiation and delithiation. A soft elastomer substrate in the Si anode plays a beneficial role for improved performance of the battery, which suggests a general way to solve the bottleneck problem for Si anodes.
