Failure Mechanisms and Strategies Toward Flexible Zinc‐Air Batteries

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(44)

Published: July 1, 2024

Abstract Flexible zinc‐air batteries (FZABs) have emerged as a promising alternative to lithium‐ion in flexible electronic devices due the advantages of excellent mechanical properties, high energy density, and notable safety. However, unclear causes performance degradation failure mechanisms FZABs significantly impede their commercialization. Therefore, extensive research is needed fully reveal factors responsible for decline FZABs. In this review, FZABs' key components, including Zn anode, solid electrolyte, catalyst air cathode, electrolyte/electrode interface are analyzed discussed. To promote further development FZABs, series challenges corresponding strategies summarized analyzed. Finally, future envisioned. This paper aims comprehensively elucidate guide high‐performance thus

Discover the Evolution: A Comprehensive Review of Transition and Rare Earth Metals for Oxygen Reduction Reaction, from Mono to High‐Entropy Catalysts

The Chemical Record, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract Green energy, including metal‐air batteries and fuel cells, is the key solution to climate change. The efficiency of these energy technologies depends on oxygen reduction reaction (ORR) at cathode, which a slow process requiring expensive noble metal catalysts, like platinum, for improvement. high cost this catalyst restricts its widespread use in producing cells. An alternative approach utilize non‐noble metals, such as transition rare earth are more cost‐effective demonstrate comparable durability effectiveness metals. With their affordability distinct electronic structure, metals have potential revolutionize industry. Transition can enhance ORR catalysts by manipulating surface molecular makeup through ′doping′ ′synergistic effects′. This article discusses roles various process, covering fundamental advanced levels, well progression from mono high‐entropy systems (systems with increasing complexity improved performance), bi‐, tri‐, tetra‐metallic comprehensive manner, emphasizes opportunities researchers propose innovative strategies optimizing process.
