A highly stable zinc–air battery based on a non-alkaline agar gel electrolyte

Key Points

• The research aims to develop a stable zinc–air battery using a non-alkaline agar gel electrolyte.
• Constructed the battery using direct injection and encapsulation processes.
• Utilized an agar gel that undergoes heating-dissolution and cooling-solidification.
• Assessed the zinc utilization rates after battery assembly.
• Achieved high zinc utilization rates in the battery setup.
• Demonstrated stability of the zinc-air battery over time.
