Iron-nickel-carbon catalyst makes zinc-air battery rechargeable for 500 cycles

A team led by Professor Jörg J. Schneider at TU Darmstadt has demonstrated an iron-nickel-carbon material that makes zinc-air batteries rechargeable. The battery withstood up to 500 charge-discharge cycles, though such batteries store significantly more energy than lithium-ion ones.

• Zinc-air batteries store more energy than lithium-ion ones
• Iron-nickel-carbon catalyst enabled up to 500 cycles
• Such batteries were previously nearly impossible to recharge
• Work led by Professor Jörg J. Schneider
