A hygroscopic layer plays an important role in improving the output abilities of energy generation from ubiquitous moisture, whose mechanism is unclear. Herein, three kinds hydrogels with different pore structures/functional groups are designed as layers, and a universal strategy was proposed to assemble them into hydrogel-based moisture-electric generators (HMEGs). The hydrogels' structure affects moisture absorption rate, while functional regulate diffusion path water. HMEG's power synergistic effect ionic streaming potential, which closely related water within material not directly amount absorption. HMEG, absorbs quickly, stores efficiently, releases slowly, has excellent performance stable voltage output. Based on this mechanism, HMEG employed calcium chloride-poly(vinyl alcohol)-poly(N-isopropylacrylamide) (CPVPN), semi-interpenetrating network (semi-IPN) hydrogel showed open-circuit high 0.34 V density 33.23 μA cm–3. This study opens perspective provides insights high-performance design.

Abstract All‐solid‐state lithium (Li) metal batteries (ASSLMBs) employing sulfide solid electrolytes have attracted increasing attention owing to superior safety and high energy density. However, the instability of against Li induces formation two types incompetent interphases, electrolyte interphase (SEI) mixed conducting (MCI), which significantly blocks rapid Li‐ion transport uneven deposition continuous interface degradation. In this contribution, a dynamically stable (S‐MCI) is proposed by in situ stress self‐limiting reaction achieve compatibility with composite (Li 6 PS 5 Cl (LPSCl) 10 GeP 2 S 12 (LGPS)). The rational design utilizes expansion induced decomposition turn constrain further LGPS. Consequently, S‐MCI inherits dynamical stability LPSCl‐derived SEI lithiophilic affinity Li–Ge alloy LGPS‐derived MCI.
