Graphite bipolar plates have the characteristics of high conductivity, high corrosion resistance, high mechanical strength, chemical stability and thermal stability.
It is widely used in electrochemical industry, power industry, metallurgical industry and other fields. Especially in fuel cells, graphite bipolar plates are one of the core components, playing important roles such as supporting membrane electrodes, providing fluid channels, separating gases, collecting electrons and conducting heat.
L.T Group has a comprehensive product and technology portfolio that focuses on four field of graphite - ultrafine particle graphite mould,graphite electrode, graphite crucible, as well as other products mainly made of graphite.
Graphite materials exhibit unique properties such as good electrical and thermal conductivity, heat and corrosion resistance, low friction, and reduced weight while at the same time maintaining high strength. Due to the shortage of energy and raw materials, our high performance products made from graphite are in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials.
The advantages of graphite bipolar plates mainly include high conductivity, strong corrosion resistance, good sealing and long life.
1. Graphite bipolar plates have high conductivity and can effectively transfer electrons to support electrochemical reactions.
2. Strong corrosion resistance can resist corrosion in electrochemical reactions, thereby extending the service life of the battery.
3. Graphite bipolar plates also have good sealing, which can ensure that the reaction gas inside the battery is evenly distributed and keep the temperature of the battery stack evenly distributed to achieve heat dissipation.
4. The long life characteristics of graphite bipolar plates mean that it can maintain stable performance over long periods of use, reduce replacement frequency, and reduce maintenance costs
