Extending the Cycle Lifetime of Solid-State Zinc-Air Batteries by Arranging Stable Zinc Species Channels

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(7), С. 8885 - 8894

Опубликована: Фев. 8, 2024

The solid-state zinc-air batteries have attracted extensive attention due to their high theoretical energy density, safety, and the compact structure. In this work, a novel hydrogel electrolyte was developed that equipped with an interpenetrating network of zinc polyacrylate (PAZn) polyacrylamide (PAM). At same time, cyclodextrin derivative sulfonate groups introduced as additive. From design anionic in network, effective stable channels for species been established. unique structure additives regulates uniform deposition zinc. After using electrolyte, cycle lifetime assembled significantly extended. byproducts were greatly suppressed generated smooth electrode surface after charge–discharge cycling.

Manipulation of Electronic States of Pt Sites via d-Band Center Tuning for Enhanced Oxygen Reduction Reaction in Proton Exchange Membrane Fuel Cells

Inorganic Chemistry, Год журнала: 2024, Номер 63(4), С. 2138 - 2147

Expediting the torpid kinetics of oxygen reduction reaction (ORR) at cathode with minimal amounts Pt under acidic conditions plays a significant role in development proton exchange membrane fuel cells (PEMFCs). Herein, novel Pt–N–C system consisting single atoms and nanoparticles anchored onto defective carbon nanofibers is proposed as highly active ORR catalyst (denoted Pt–N–C). Detailed characterizations together theoretical simulations illustrate that strong coupling effect between different sites can enrich electron density sites, modify d-band electronic environments, optimize intermediate adsorption energies, ultimately leading to significantly enhanced performance. Specifically, as-designed demonstrates exceptional properties high half-wave potential 0.84 V. Moreover, mass activity reaches 193.8 mA gPt–1 0.9 V versus RHE, which 8-fold greater than Pt/C, highlighting enormously improved electrochemical properties. More impressively, when integrated into electrode assembly an air-fed PEMFC, achieved higher maximum power (655.1 mW cm–2) compared Pt/C-based batteries (376.25 cm–2), hinting practical application PEMFCs.
