Unbiased solar energy storage: photoelectrochemical redox flow battery

February 22, 2016

This article deals with a proposal for how to store solar energy, that originates from converted sunlight into electrochemical energy in a redox flow battery (RFB).

Insights into all-vanadium redox flow battery: a case study on components and operational conditions

March 20, 2018

This article regards the notion that it is possible to increase the performance of a vanadium redox flow cell (VRFC) without it affecting a monetary aspect.

2D dynamic phenomenological model of vanadium redox flow batteries - analysis of overpotential

November 3, 2020

The article presents a phenomenological model of a vanadium redox flow battery which is used to assess the concentration overpotential during charge-discharge cycling at different operating conditions.

The article also presents a method to determine the mass transfer coefficient and a strategy to reduce the concentration overpotential.
