Special Issue Information

Dear Colleagues,

In recent years, renewable energy is gradually changing from auxiliary energy to dominant energy. The establishment of a new power system with "new energy + energy storage" as the main body has put forward new requirements for high-power, large-capacity, and long-term energy storage technology. Redox flow batteries as the novel and intrinsically safe energy storage technology has the characteristics of long charge and discharge cycle life, recyclable electrolyte, good life cycle economy and environmental friendliness, which has received widespread attention from academia and industry.

In response to the major demand for high-security, large-scale stationary electrochemical energy storage technology such as new power systems, it is necessary to increase the research and development of key technologies for new generation flow batteries in the future, break through the key scientific and technical challenges in new technologies, and solve the problems of aqueous flow batteries. Flow battery technology faces problems such as scale, cost, and lifespan, so as to achieve the orderly and healthy development of the entire flow battery industry chain and provide technical support for the energy revolution and energy structure adjustment.

This Special Issues focuses on technologies of redox flow batteries, such as novel ion exchange membranes, modified carbon fiber electrodes, and newly designed electrolytes (aqueous/non-aqueous/organic).

The topics of interest related to redox flow batteries include, but are not limited to:

  • Ion exchange membranes or porous separators with high ionic selectivity;
  • New electrolyte system to realize high energy density;
  • Modified carbon fiber electrodes for high kinetics during redox reactions;
  • Design and optimization of flow fields and channels;
  • Modelling and simulation study;
  • Online testing (e.g., electrochemical impedance spectroscopy, incremental capacity);
  • Power electronics for the high quality output;
  • Battery Management System;
  • Design of redox flow battery systems for microgrids;
  • Technical and economic assessments;
  • Life prediction and fault diagnosis.

In this work, a comprehensive multi-physics electrochemical hybrid stack model is developed for a vanadium redox flow battery (VRFB) stack considering electrolyte flow, mass transport, electrochemical reactions, shunt currents, and as heat generation and transfer simultaneously. Compared with other VRFB stack models, this model is more comprehensive in considering the influence of multiple factors. Based on the established model, the electrolyte flow rate distribution across cells in the stack is investigated. The distribution and variation in shunt currents, single-cell current and single-cell voltage are analyzed. The distribution and variation in temperature and heat generation and heat transfer are also researched. It can be found that the VRFB stack temperature will exceed 40 °C when operating at 60 A and 100 mA cm−2 at an ambient temperature of 30 °C, which will lead to electrolyte ion precipitation, affecting the performance and safety of the battery. To control the stack temperature below 40 °C, a new tank cooling control strategy is proposed, and the suitable starting cooling point and the controlled temperature are specified. Compared with the common room cooling strategy, the new tank cooling strategy reduces energy consumption by 27.18% during 20 charge–discharge cycles. Full article
