Nickel-based materials are considered the most promising anode catalysts for practical applications in low-cost AEMFCs, but designing Ni-based catalysts with breakthrough performance remains a major challenge due to the slow kinetics of the anodic hydrogen oxidation reaction (HOR) in alkaline media. In this review, the electrocatalytic mechanisms of the alkaline HOR and the rigorous methods for assessing the performance of Ni-based catalysts are presented as the cornerstones for designing Ni-based catalysts.

Structure designs, including constructing architectural Li anode, three-dimension (3D) structure OSEs and integrated cathode can significantly increase the effective contact area between electrodes and OSEs to facilitate the interfacial ion transport. The interfacial modifications are utilized to improve the wettability of OSEs for lithium metal anode, enhance the interfacial ion transport, and stabilize the OSEs/electrodes interface.

Triboelectric sensing technology plays a vital role in acquiring and quantifying tactile signals.

To address this challenge, our study proposes a highly damping triboelectric gel based on a hydrogen bonding assisted microphase separation strategy. In microphase separation, the soft phase provides the viscoelasticity needed for the gel, while the hard phase dissipates shock energy. This energy dissipation mechanism enables the gel to achieve excellent damping performance (tan δ = 0.68 at 1Hz), skin-like softness (Young’s modulus of 130 kPa), and stretchability (> 900 %). The resulting self-damping tactile patch effectively absorbs and dissipates external vibrations, ensuring a stable and reliable wearable tactile sensing device.
