Nonpolarizing oxygen-redox capacity without O-O dimerization in Na2Mn3O7

Majority of oxygen-redox electrodes exhibit a large voltage hysteresis but its origin is not fully understood. Here, the authors use combined RIXS and magnetic measurements to provide insights into the origin of the typically large voltage hysteresis observed upon oxygen redox.
