Graphite Felt
Graphite felts are used in a vanadium redox flow batteries (VRB). The high conductivity, high purity, and chemical resistance of felts make them ideal for the demanding design criteria of flow battery developers.

- Specification
With the popularity of alternative energy, especially the solar and wind energy, demands for more cost effective and more reliable energy storage sysment have soared in the past decade. Compared with other storage systems, Vanadium Redox Flow Battery (VRB) has several advantages as low-overall cost, longer life cycle, and exerllent discharge capability.
CeTech has been working with several VRB manufacturers to find out the best graphite felt products used in VRBs. Since graphite felt is used as an electrode, its quality and property are very important for the stability of a VRB system.
Product Features:
Excellent chemical stability
Good electrical conductivity
Even thickness
Long life cycle
