In recent years, energy storage technology has developed rapidly. New energy storage has entered thestage of large-scale development from the initial stage of commercialization and has initially met theconditions for large-scale commercial application. Liquid flow batteries have the advantages of high safetylong cycle life, recyclable electrolyte, high cost-effective life cycle, and environmental friendliness.

They areconsidered to be one of the preferred technologies for large-scale energy storage technology and havebroad application prospects.

In 2018 Foshan Nanhai Baotan Graphite Products Co., Ltd. explored new applications of graphite. Graphitebipolar plates have good electrical and thermal conductivity, and are easier to process and cheaperthan metal plates. Explore the feasibility and prospects of mass production of bipolar plates.

Types of energy storage batteries

The flow battery systems that are currently being widely researched and commercialized include:all-vanadium flow battery, zinc-bromine flow battery, iron-chromium flow battery, sulfur-iron flow battery, etc.

The role of bipolar plates in energy storage batteries

Bipolar plates are important components in flow batteries, used to connect and separate multiple batteries, conduct the current generated in the battery, and provide support for the reaction ,electrodes in the energy storage battery. Since the electrolyte of the flow battery is often an acidic solution, the bipolar plates of the flow battery need to have good conductivity and chemical stability, as well as certain mechanical
strength and air tightness.

Energy storage battery graphite plate

Metal bipolar plate materials often choose gold, titanium, stainless steel, etc. with good corrosion resistance. Precious metals are not suitable as bipolar plate materials due to cost issues. Although stainless steelis cheap and has good machining performance, it is prone to corrosion in acidic environments and highpotentials. Therefore, existing metal materials and processes are not suitable for bipolar plates for energy storage batteries.
