Researchers from Zhejiang Normal University have made significant advancements in the development of flexible zinc-air batteries, which have the potential to revolutionize wearable electronics. According to a new report, the team has successfully synthesized a highly conductive solid-state electrolyte membrane using a rapid-polymerization strategy, enabling flexible zinc-air batteries to achieve high voltage and long cyclability. This breakthrough has significant implications for the widespread adoption of wearable electronics.

Key Takeaways:

  • The researchers developed a rapid-polymerization strategy to synthesize a highly conductive solid-state electrolyte membrane, achieving full polymerization in just 3 minutes.
  • The membrane exhibits an ultrahigh ionic conductivity of 0.75 S cm^(-1) and enables flexible zinc-air batteries to operate at a discharge plateau of 1.2 V at 10 mA cm^(-2) and 4200 minutes of cyclability at 1 mA cm^(-2).
  • The resultant flexible zinc-air batteries demonstrated a breakthrough open-circuit voltage of 2.16 V, representing the highest recorded value among reported flexible zinc-air battery systems.
  • The research resolves the challenges of interface separation and low-voltage limitations in zinc-air batteries.
  • The team's innovative membrane design enables spatially decoupled acid-alkaline integration within a single matrix.
  • The flexible zinc-air batteries developed in this study have the potential to enhance the development of wearable electronics.
