A long-life Na–air battery based on a soluble NaI catalyst†
Abstract
A Na–air battery with NaI dissolved in a typical organic electrolyte could run up to 150 cycles with a capacity limit of 1000 mA h g−1. The low charge voltage plateau of 3.2 V vs. Na+/Na in a Na–air battery should mainly be attributed to the oxidation reaction of active iodine anions.
