Title:
FLOWLESS REDOX BATTERY
Document Type and Number:
Japanese Patent JP2023125316
Kind Code:
A
Abstract:
To provide a flowless redox battery which is lightweight, improved in shape freedom, especially capable of being thinned like paper and capable of dealing with thousands of times of charge/discharge.SOLUTION: A flowless redox battery includes electrodes formed from carbon fiber fabrics, electrolyte layers and a separator. The electrolyte layers are provided on both surfaces of the separator, and the electrolyte layers provided on both the surfaces are held by two electrodes. The electrolyte layer is an electrolyte paste layer containing a vanadium ion redox solution with diluted sulfuric acid as an electrolyte and carbon fillers. Regarding the carbon fiber fabric forming the electrode, a specific surface area ranges from 0.1 m2/g to 100 m2/g, a thickness ranges from 50 μm/Mpa to 200 μm/Mpa, a basis weight ranges from 20 g/m2 to 120 g/m2, a thickness resistance value ranges from 2.1 mΩ/Mpa/cm2 to 8.0 mΩ/Mpa/cm2, and a distance between the two electrodes is 0.05 mm or more and 0.5 mm or less.SELECTED DRAWING: Figure 5
