Abstract Zinc‐based batteries are potential candidates for flexible energy storage due to their high capacity, low cost, and intrinsic safety. Hydrogel electrolytes with saturated aqueous solvents can provide remarkable electrochemical performance while retaining satisfactory flexibility zinc‐based batteries. The past decades have witnessed fast growth. However, the study of hydrogel under extreme conditions is still in early stages many technical issues remain be addressed. In this review,...

Abstract Lithium‐sulfur batteries (LSBs) are considered a promising next‐generation energy storage device owing to their high theoretical density. However, overall performance is limited by several critical issues such as lithium polysulfide (PS) shuttles, low sulfur utilization, and unstable Li metal anodes. Despite recent huge progress, the electrolyte/sulfur ratio (E/S) used usually very (≥20 µL mg −1 ), which greatly reduces practical density of devices. To push forward LSBs from lab...
Flexible zinc (Zn)-air batteries are recognized as a next-generation battery candidate for emerging smart-wearable devices in portable use. Unfortunately, the high cost of flexible electrolytes and complex synthesis process limit commercial application Zn-air batteries.

Flexible solid-state zinc-air batteries (ZABs) generally suffer from poor electrolyte/electrode contact and mechanical degradation in practical applications. In addition, CO2 corrosion is also a common issue for ZABs with alkaline electrolyte.

Through simple cooling process, transforms solid state to liquid not only restore deformed layer its original but rebuild intimate...
The energy density of lithium-sulfur batteries (LSBs) is currently hampered by modest sulfur loadings and high electrolyte/sulfur ratios (E/S). These limitations can potentially be overcome using easy-to-infiltrate hosts with catalytic materials. However, materials in such are very susceptible to agglomeration due the lack efficient confinement structures. Herein, carbon dots as an aggregation limiting agent, successful fabrication self-supporting nanofibers (CNF) containing Ni-single-atoms...
