Metal-air batteries

Metal-air batteries are addressed through our activities on oxygen reduction and oxygen evolution catalysts and electrodes (e.g. stainless-steel electrodes for efficient oxygen evolution reaction [1-3] or evolution reaction [4]), but also through a priviledged collaboration with Easyl. In that collaboration, we develop architectured Zn-based electrodes for long-term charge/discharge cycling and high-capacity operation [5-6].
