How Much do You Know about Battery Graphite Felt ?
Battery Graphite Felt, we also call it Activated Energy Storage Felt, it is mainly used in energy storage battery.
CD Graphite company’s BGF is used for the storage of graphite felt. It can make the charge and discharge’s current density 2 times higher than before. And all indicators are much better than other peers’ similar products, including stable electrochemical performance, battery charge and discharge stability, good flatness and low resistance. Voltage and energy efficiency can be increased more than 30%, and no energy efficiency attenuation in the long term of charge and discharge process. Especially activated enery storage felt, in addition to the basic battery felt characteristics, it can also improve the liquid absorption rate and electrolyte utilization, and can be used for high density current charging and discharging.
Our company research and design some sets of production equipments and production lines independently, including large continuous graphite self-developed high temperature furnace. It is the first domestic energy storage graphite felt continuous production line in China.

Our company has focused on the production of liquid flow battery electrode materials research and development more than 10 years. Our first generation of energy storage graphite felt became the first domestic alternative to foreign electrode graphite felt products. We have a unique production process and rich project experience in the production of electrode materials for liquid flow batteries.
We have completed the continuous production of graphite felts, improved product stability and batch consistency, and achieved a creative breakthrough in product quality.
Because our company integrates R&D and production, and has designed and developed several production lines independently, among which our continuous carbonization furnace and self-developed continuous graphitization furnace have changed the traditional gap furnace production method.
Our company produces energy storage carbon materials and high-temperature vacuum furnace with hot field carbon materials, used in liquid current storage battery and large-scale high-temperature vacuum furnace and photovoltaic and other heat treatment industry.
Energy storage graphite felt (liquid current battery electrode) is our leading product.
Our company independently developed graphite felt continuous production line and activation equipment and process, so that the product performance is greatly improved, the battery performance is stable, in the high current density of long-term charging and discharging without attenuation. We have established a good reputation in the domestic and foreign energy storage industry, including most of the major domestic users and some foreign users.
The main foreign customers are UK, USA, Germany, Korea, Austria, Spain, New Zealand and other countries.
