From Na to K‐Based Prussian Blue: A Path Toward Cathode Materials for Extreme Environment

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Abstract Prussian blue (PB) is regarded as a promising host for Na or K storage because of its sustainable precursor elements (e.g., Mn, Fe) and open framework structure. However, unstable structure, high crystal H 2 O content, risky HCN generation restrain practical applications. In this work, after systematical investigation structural evolution from Na‐based to K‐based PB relationship with electrochemical properties, it clarified that low water trace doping are essential robust structure stable cycling PB. It found Na‐doped exhibits comprehensive properties content (3.2 wt%), thermal stability (over 340 °C), superior (84.3% 6300 cycles at 5 C). Besides, the can also present under harsh conditions, such intermittent‐overcharge/overdischarge steps (4.8 V/1.2 V, 93.3% 2100 C), in wide voltage range (93.2% 1000 1.5‒4.5 V/5 rate (83.7% 4350 10 temperature (92.0% 1650 45 °C/1 The attributed robustness even conditions.

Polyacrylamide Soft Colloidal Electrode for Long-Lasting Aqueous Zn -I Batteries

Published: Jan. 1, 2025

Aqueous Zn-I batteries hold great potential for stationary energy storage applications. However, their development is challenged by limited device innovation, hindering improvements in long-term operation. In this study, we report an aqueous battery design that leverages the water distribution control effect of sulfate ions (SO4)2–. Due to strong affinity compared polyacrylamide (PAM), (SO4)2– induce phase separation PAM from electrolyte, preventing its dissolution. By introducing iodide species within soft colloid, construct battery. Comprehensive electrochemical performance evaluations, including rate capability, cycling stability, fast-charging, fluctuating charge conditions, various states charge, and self-discharge performance, demonstrate stability over 30000 cycles with a 94.3% capacity retention. Moreover, demonstrated compatibility practical solar panels, suggesting integration sustainable resources future. This study provides solid innovation advancing technology.
