Storing energy harvested by triboelectric nanogenerators (TENGs) from ambient mechanical motion is still a great challenge for achieving low‐cost and environmental benign power sources. Here, an all‐solid‐state Na‐ion battery with safe and durable performance used for efficient storing pulsed energy harvested by the TENG is demonstrated. The solid‐state sodium‐ion batteries are charged by galvanostatic mode and pulse mode with the TENG, respectively. The all‐solid‐state sodium‐ion battery displays excellent cyclic performance up to 1000 cycles with a capacity retention of about 85% even at a high charge and discharge current density of 48 mA g −1 . When charged by the TENG, an energy conversion efficiency of 62.3% is demonstrated. The integration of TENGs with the safe and durable all‐solid‐state sodium‐ion batteries is potential for providing more stable power output for self‐powered systems.
