Guiding Uniform Al Stripping with a Polymer Sol Electrolyte for Long-Lasting Al-Air Batteries

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(9), P. 4170 - 4179

Published: May 1, 2024

Aqueous aluminum-air batteries (AABs) have garnered significant research interest due to their inherent safety, high energy density, and cost-effectiveness advantages. Nevertheless, the widespread application of AABs is constrained by challenges such as undesired parasitic self-corrosion continuously accumulated byproducts over time. Here, an anticorrosive polyacrylamide (PAM) sol electrolyte designed modulate interfacial reactions at aluminum (Al) anodes. The PAM with a hydrogen bonding network refines electrolyte's solvated environment, thus mitigating Al anode corrosion 56.36% when benchmarked against 20 wt % sodium chloride (NaCl) electrolyte. Furthermore, this approach ensures uniform stripping behavior manages generation hydroxide electrode/electrolyte interface. With respect rampant precipitates in pH-neutral electrolytes, assists facilitating stable dispersion (Al(OH)3) curtailing excessive buildup precipitates, thereby prolonging battery's operational life. Consequently, using attain remarkable specific capacity 2312 mAh g–1, alongside extended durability 73.3 h cyclic on/off testing scenarios. This study offers viable strategy for regulating anodes boosting long-term stability AABs.
