The P3D SSFB cell here considered is composed of flow channels 7 cm long, 1 mm wide between current collector and separator and 2 mm high in each compartment. the current density was therefore calculated over current collectors of 140 mm 2 surface area.
His other innovation is to replace the flow battery''s current collector, which is typically a stationary mesh of carbon fibres that the electrolytes must pass through.
Here we used LiFePO 4 (LFP) as an example to demonstrate a single-component slurry based Li-LFP flow battery with a carbon felt 3D current collector, achieving 40 vol % LFP concentration in slurry with a volumetric capacity of 68 Ah L −1 while maintaining the viscosity of single-component LFP slurry to be significantly smaller than …
