This article mainly studies TENGs working in high humidity environments and summarizes four methods to improve moisture resistance, including package, construction of hydrophobic/superhydrophobic surfaces, hydrogen bonding enhancement, and other methods. And the application of TENGs in humidity sensors, energy harvesters, and motion fields was elaborated, and future research directions were discussed.

This review examines lithium-ion batteries associated with the global energy transition, particularly for use in electric vehicles and renewable energy-storage systems. It addresses environmental concerns and resource scarcity, emphasizing the need for sustainable recycling strategies. Various recycling methods, in particular electrochemical techniques, are evaluated for metal recovery. Integrating these methods into battery-recycling infrastructure is advocated to address resource depletion and environmental challenges.

Thin-walled carbon nanotubes (TWCNT) were synthesized and assemblies demonstrated superior electric characteristics for perovskite solar cells (PSCs). We introduced low-molecular-weight PTAA infiltration into TWCNT electrodes to fulfill the porosity and modify the interface between TWCNT and perovskite layer. Furthermore,  a new design of TWCNT rear electrode hidden encapsulation technology enables the demonstration of the stable PSCs.

A remarkable PCE of 14.69% was achieved by enhancing the morphology of air-processed sub-modules (55 cm²) fabricated using halogen-free solvents (O-xylene). This performance was achieved by regulating surface morphology, intra- and intermolecular interactions, and film optimal aggregation.

An orthogonal solution-processable spray-coating method forms an n-type Cs₂SnI₆ double perovskite (Sn-DP) layer on a PEA_0.15FA_0.85SnI₃ perovskite layer (Sn-P), achieving 12.9% PCE and minimizing V_oc loss to 0.38 V. This architecture enhances electron transport, reduces defects, and offers 1000-h stability under continuous illumination, promising efficient, stable tin-based lead-free solar cells.
