Product Introduction Of High Temperature Proton Exchange Membrane:
The Proton High Temperature Exchange Membrane we produce is mainly used in the field of all-vanadium liquid flow batteries. It plays the role of conducting protons and blocking vanadium ions, which determines the charge and discharge performance of the Proton High Temperature Exchange Membrane. During the tape casting production process, the strength, moisture retention and vanadium resistance of the Proton High Temperature Exchange Membrane are enhanced by adding special materials. The Proton High Temperature Exchange Membrane we produce also shows excellent tolerance to strong acids and strong oxidizing electrolytes in vanadium batteries, ensuring long-term durability and stability in harsh chemical environments.
Product Advantages Of High Temperature Proton Exchange Membrane:
Through the localization transformation strategy, the Proton membrane exchange we produce is expected to achieve certain advantages in production costs compared with imported Nafion membranes, thereby reducing the overall cost of high-temperature proton exchange membranes. In the 120mA·cm-2 charge and discharge cycle test, the Proton membrane exchange we produce has demonstrated the potential of high-temperature proton exchange membranes in large-scale energy storage applications with better performance.
