High performance lithium-sulfur batteries for storing pulsed energy generated by triboelectric nanogenerators
Abstract 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...
