“…As far as the current research trend on nonaqueous RFBs is concerned, it focuses principally on the development of redox active materials, such as metal−ligand complexes and organic molecules. 536 However, the research on nonaqueous RFBs is in its preliminary developmental stages. In addition, this battery technology is facing dire challenges in terms of its limitation to scale-up and to reach the energy densities of its aqueous counterparts owing to extremely low solubility of the active redox species in nonaqueous electrolytes.…”

“…Furthermore, inexpensive and sustainable organic redox materials have emerged as wholesome alternatives to the present metal-based redox species. 536 It is believed that redox potential and solubility can be tailored by introducing specific side groups on the organic molecular structures. Although the long-term stability of organic redox species has not yet been verified, the organic RFBs with advanced porous membranes are speculated to be one of the most promising, inexpensive, and highly efficient candidates as next-generation RFBs for GSES.…”

Ever-increasing global energy consumption has driven the development of renewable energy technologies to reduce greenhouse gas emissions and air pollution. Battery energy storage systems (BESS) with high electrochemical performance are critical for enabling renewable yet intermittent sources of energy such as solar and wind. In recent years, numerous new battery technologies have been achieved and showed great potential for grid scale energy storage (GSES) applications. However, their practical applications have been greatly impeded due to the gap between the breakthroughs achieved in research laboratories and the industrial applications. In addition, various complex applications call for different battery performances. Matching of diverse batteries to various applications is required to promote practical energy storage research achievement. This review provides indepth discussion and comprehensive consideration in the battery research field for GSES. The overall requirements of battery technologies for practical applications with key parameters are systematically analyzed by generating standards and measures for GSES. We also discuss recent progress and existing challenges for some representative battery technologies with great promise for GSES, including metal-ion batteries, lead−acid batteries, molten-salt batteries, alkaline batteries, redox-flow batteries, metal−air batteries, and hydrogen-gas batteries. Moreover, we emphasize the importance of bringing emerging battery technologies from academia to industry. Our perspectives on the future development of batteries for GSES applications are provided.

“…Ligand design can have a remarkable impact of the charge carrier solubility, stability and redox properties and is therefore a key research focus for optimisation of metal coordination complexes. We direct the interested reader to two recent reviews for a more thorough examination of metal coordination complexes in RFBs [24,26].…”

Increasing the volumetric energy density of redox flow batteries beyond that of the archetypal all-vanadium system requires the development of highly soluble charge carriers that can store multiple electrons per charge cycle. In this review article we will describe the design and performance of a range of new charge carriers for flow batteries, with an emphasis on those with multi-electron redox properties. These include fullerene derivatives, multifunctional organic systems, metal coordination complexes, and polyoxometalates. Our discussion will include an evaluation of the fundamental physical and electrochemical properties of the charge carriers and their impact on battery performance and energy density.
