Summary: A new triboelectric-electromagnetic hybrid nanogenerator (TEHG) has been developed, which combines a soft ball-based triboelectric nanogenerator (SB-TENG) and an electromagnetic generator (EMG) for efficient energy harvesting from low-frequency water waves. The critical parameters affecting the energy harvesting performance of the SB-TENG have been investigated, including the type of filled liquids, silicone shell thickness, number of layers, and added soft balls. Under an operating frequency of 1 Hz, the SB-TENG and EMG can reach a maximum output peak power of 0.5 and 8.5 mW, respectively. This study not only presents a new design and approach to enhance the output performance of TENGs, but also demonstrates the potential of a self-powered water-sensing system driven by low-frequency water waves.

Summary: The retirement of lithium-ion batteries (LIBs) due to the electrification of transportation has hindered sustainability. Challenges in recycling the spent LIBs include contamination, complicated processes, massive chemical/energy consumption, and secondary pollution. A material and energy dual circulations method is proposed here to address these challenges, enabling the closed-loop and sustainable recycling of components in spent LIBs. The method involves the electrochemical dual-electrode recycling technology to regenerate LIBs and fabricate a triboelectric nanogenerator (TENG) in the material circulation, while the fabricated TENG converts ambient wind energy into electricity to power the material circulation in the energy circulation. This system shows high element selectivity, self-powering capability, simplified treating procedure, and high profit, making it feasible for commercial application.
