The high voltage and low current output of triboelectric nanogenerators (TENGs) can avoid safety problems generated from normal high-voltage sources. However, conventional alternating current TENGs (AC-TENGs) are not a good choice for ionizing air without rectifiers. The newly developed electrostatic breakdown ternary direct-current TENG (EBT-DC-TENG) is a simple and low-cost structure to be used in dust removal. However, spark discharge occurs between the back electrodes of the EBT-DC-TENG when connected to heavy loads, which limits its high-voltage applications.

By integrating the optimized EBT-DC-TENG with a dust removal device, we have demonstrated an effective and safe indoor dust removal system.

While previous research has largely concentrated on enhancing the ionic conductivity and electrochemical stability of SSE, the mechanical properties of the SSE/Li interface, a critical factor in suppressing dendrite initiation and propagation, have received inadequate attention. To address this gap, this work develops an interface modification strategy to enhance both adhesion and elasticity at the SSE/Li interface, thereby ensuring a robust interface during prolonged cycling. Specifically, tin foil is introduced into the SSE/Li interface to form the Li-Sn alloy during cycling. The resulted Li-Sn alloy ensures intimate SSE/Li contact through chemical adhering effect and simultaneously provides a 35-fold increase in elasticity compared to cycled Li electrode, effectively inhibiting the growth of Li-dendrite. Furthermore, the introduction of tin foil mitigates the occurrence of side reactions at SSE/Li interface. As a result, the LFP/LATP/Sn/Li cell (300 cycles, 83.9 % capacity retention) demonstrates doubled lifetime of LFP/LATP/Li cell (155 cycles, 80 % capacity retention) at 0.5 C.
