The piezoelectrochemical coupling between mechanical stress and electrochemical potential is explored in the context of mechanical energy harvesting and shown to have promise in developing high‐energy‐density harvesters for low‐frequency applications (e.g., human locomotion). This novel concept is demonstrated experimentally by cyclically compressing an off‐the‐shelf lithium‐ion battery and measuring the generated electric power output.
