A new type of responsive battery with the fascinating feature of pressure perceptibility has been developed, which can spontaneously, timely and reliably control the power outputs (e.g., current and voltage) in response to pressure changes. The device design is based on the structure of the Zn–air battery, in which graphene‐coated sponge serves as pressure‐sensitive air cathode that endows the whole system with the capability of self‐controlled energy release. The responsive batteries exhibit superior battery performance with high open‐circuit voltage (1.3 V), and competitive areal capacity of 1.25 mAh cm −2 . This work presents an important move towards next‐generation intelligent energy storage devices with energy management function.
