Nafion™ membranes for energy storage

　　Maximize renewable energy with Nafion™ membranes

　　Efficient and effective storage is critical to the global electricity supply and energy infrastructure as the industry looks for renewable energy sources for power generation. Wind and solar energy are considered very promising renewable sources of energy. However, there are still constraints for large-scale adoption due to their highly variable energy production and mismatched production and demand conditions.

　　Nafion™ membranes make it possible to store renewable energy by enabling technologies such as liquid flow batteries and hydrogen production. These technologies allow utilities to store energy for a rainy day, maximizing renewable energy production without destabilizing the utility grid. By stabilizing the variable nature of renewable energy, we can make the full use of natural resources rather than face the vagaries of climate changes.

　　Large scale energy storage system powered by long usage life flow battery

　　A flow cell is an electrochemical cell whose chemical energy is stored in two different liquid electrolyte solutions. These electrolyte solutions are pumped into the battery, where a chemical reaction takes place to produce electricity.

　　During this process, the membrane always keeps the electrolyte separated, allowing only the needed charge carrier ions to pass through or into the membrane. This separation of electrolytes also makes the chemical reaction reversible and enables the battery to be recharged repeatedly.

　　With the increasing demand for more efficiently, viable and large-scaled energy storage systems, Nafion™ membranes provide key advantages for the development of large-scale, long usage life of flow batteries.

　　These include:

　　Excellent mechanical properties;

　　High ionic conductivity;

　　High selectivity;

　　Chemical stability.

　　Our company practice the concept of “green and environmental protection” of clean energy through continuous innovation to produce safer, more economical and flexible Nafion™ membranes.
