Abstract
Generally, non-aqueous organic redox flow batteries (NAORFBs) operate in glove box conditions to stabilize the charged species generate during energy storage. Even a trace amount of moisture entering the system destabilizes the capacity of the battery. Such systems may not be commercially viable due to stringent ambient requirements. To address this issue, we demonstrate a NAORFB capable of running in inert condition (without glovebox) using a mixed electrolyte of 0.2 M benzylviologen hexafluorophosphate [BV(PF6)2] and N-hexyl phenothiazine (HPT) at 40 mA cm−2 current density. This system exhibits cycling stability up to 100 cycles with 0.0051 % capacity fade per cycle and 6.09 % capacity fade per day.
