Novel Flow Battery with Long Lifetime

The cost of wind and photovoltaic electricity has dropped so much that one of the greatest technical barriers to their widespread substitution for fossil electricity is their intermittency. Cost-effective, safe, and scalable stationary electricity storage could solve this problem.

This invention “Novel Flow Battery with Long Lifetime” is a long lifetime aqueous redox flow battery that can operate at pH as low as 12, while maintaining an open-circuit voltage of over 1 volt.

This invention adds the important attribute of long calendar life to quinone-based redox flow batteries, which may enable massive penetration of intermittent renewable electricity.
