英文摘要	Storing pulsed energy harvested by triboelectric nanogenerators (tengs) from ambient mechanical motion is an important technology for obtaining sustainable, low-cost, and green power. here, we introduce high-energy-density li-s batteries with excellent performance for storing pulsed output from tengs. the sandwich-structured sulfur composites with multi-walled carbon nanotubes and polypyrrole serve as cathode materials that suppress the shuttle effect of polysulfides and thus preserve the structural stability of the cathode during li-ion insertion and extraction. the charging time and energy storage efficiency of the li-s batteries are directly affected by the rotation rates of the tengs. the average storage efficiency of the batteries for pulsed output from tengs can exceed 80% and even reach 93% at low discharge currents. the li-s batteries also show excellent rate performance for storing pulsed energy at a high discharge current rate of 5c. the high storage efficiency and excellent rate capability and cyclability demonstrate the feasibility of storing and exploiting pulsed energy provided by tengs and the potential of li-s batteries with high energy storage efficiency for storing pulsed energy harvested by tengs.
