Carbon fiber felt The use of carbon fiber felt as electrodes in flow batteries is becoming increasingly popular due to good electrical conductivity, light weight and high electrochemical stability ( Meng et al., 2017 ).
The application of felt electrodes is outlined on the example of the vanadium redox flow battery (VRFB). Then, the interrelation of carbon felt and carbon fiber is explained regarding the manufacturing process of carbon felts and a selection of suitable starting materials.
Although the amount of carbon fiber felt used in a flow battery system is small and does not significantly influence the total environmental impact, the relatively high energy consumption for carbon fiber felt production is considered here as the high-temperature pyrolysis may trigger high environmental impact ( Minke et al., 2017; Romaniw, 2013 ).
Among the various types of battery storage systems, flow batteries represent a promising technology for stationary energy storage due to scalability and flexibility, separation of power and energy, and long durability and considerable safety in battery management ( Alotto et al., 2014; Leung et al., 2012; Wang et al., 2013 ).
Environmental impact assessment of flow battery production was conducted. Three types of flow batteries with different design parameters were analyzed. Design factors and materials choices largely affect the environmental impact. Choices fr cell stack, electrolyte and membrane materials influence total impact.
We have systematically evaluated three different state-of-the-art flow battery technologies: vanadium redox flow batteries (VRFB), zinc-bromine flow batteries (ZBFB) and all-iron flow batteries (IFB). Eight impact categories are considered, and the contribution by battery component is evaluated.
