Hybrid Hard-Soft Materials Matrix for Energy Storage within Flow Systems

Navigant’s 2016 Energy Storage for the Grid and Ancillary Services report projects that North American grid capacity will need to increase to 12,140.8 MWh in 2025 to meet demand. Energy storage systems will play a significant role in meeting the challenges of developing a future grid with expanded distributed energy resources that still provides power reliably and efficiently. Improvements within grid-scale energy storage systems, such as redox flow batteries and hybrid energy storage materials, have drawn increased attention and research due to their promising potentials of high capacity and cycle life or high energy and density. However, redox flow batteries, despite their impressive cycle life of over 10,000 cycles and a capacity life of 10-20 years, are not widely implemented for grid storage due to their limited energy density and slow charge transfer kinetics. Additionally, hybrid energy storage materials, while promising for their high-energy and high-density potential, are severely limited for further grid-scale application due to their intrinsic material limitations. Therefore, there is an increased need for high-energy and high-power energy storage systems to meet the growing demand for grid capacity.
