Flexible Zinc–Air Batteries with Ampere‐Hour Capacities and Wide‐Temperature Adaptabilities

Advanced Materials, Journal Year: 2023, Volume and Issue: 35(13)

Published: Jan. 30, 2023

Flexible Zn-air batteries (FZABs) have significant potentials as efficient energy storage devices for wearable electronics because of their safeties and high energy-to-cost ratios. However, application is limited by short cycle lives, low discharge capacities per cycle, charge/discharge polarizations. Accordingly, herein, a poly(sodium acrylate)-polyvinyl alcohol (PANa-PVA)-ionic liquid (IL) hydrogel (PANa-PVA-IL) prepared using hygroscopic IL, 1-ethyl-3-methylimidazolium chloride, an additive twin-chain PANa-PVA. PANa-PVA-IL exhibits conductivity 306.9 mS cm-1 water uptake 2515 wt% at room temperature. Moreover, low-cost bifunctional catalyst, namely, Co9 S8 nanoparticles anchored on N- S-co-doped activated carbon black pearls 2000 (Co9 -NSABP), synthesized, which demonstrates O2 reversibility potential gap 0.629 V. FZABs based -NSABP demonstrate 1.67 mAh cm-2 long lives 330 h. Large-scale flexible rechargeable pouch cells exhibit total 1.03 Ah densities 246 Wh kgcell-1 . This study provides new information about hydrogels with ionic conductivities uptakes should facilitate the in electronics.

Edge-Hosted Mn-N₄-C₁₂ Site Tunes Adsorption Energy for Ultralow-Temperature and High-Capacity Solid-State Zn-Air Battery

ACS Nano, Journal Year: 2023, Volume and Issue: 17(10), P. 9565 - 9574

Published: May 9, 2023

Robust operation of Zn-air batteries (ZABs) with high capacity and excellent energy efficiency is desirable for practical harsh applications, whose bottlenecks are mainly originated from the sluggish oxygen catalytic kinetics unstable Zn|electrolyte interface. In this work, we synthesized edge-hosted Mn-N4-C12 coordination supported on N-doped defective carbon (Mn1/NDC) catalyst, exhibiting a good bifunctional performance reduction/evolution reaction (ORR/OER) low potential gap 0.684 V. Theoretical calculation reveals that displayed lowest overpotential ORR/OER owing to decreased adsorption free OH*. The Mn1/NDC-based aqueous ZABs deliver impressive rate performance, ultralong discharging lifespan, stability. Notably, assembled solid-state demonstrate 1.29 Ah, large critical current density 8 mA cm-2, robust cycling stability at -40 °C, which should be attributed Mn1/NDC anti-freezing electrolyte (SSE). Meanwhile, zincophilic nanocomposite SSE polarity accounts stable Zn|SSE interface compatibility. This work not only highlights importance atomic structure design electrocatalysts ultralow-temperature high-capacity but also spurs development sustainable Zn-based conditions.
