Application of high-purity graphite in "energy"
Compared with traditional energy sources, high-purity graphite is used in the "final energy". Hydrogen energy is clean, environmentally friendly, and has a high energy density, and is considered the "final energy"
As one of the main application areas of hydrogen energy, hydrogen fuel cells are used for driving cars through the oxidation-reduction reaction of hydrogen gas in the stack. Only the reaction process produces water, reaching. Therefore, hydrogen fuel cells are considered one of the ideal options due to their advantages such as high energy conversion rate, low emissions, and high energy and power density.
Graphite bipolar plates are an important component of hydrogen fuel cells. During the operation of fuel cells, it plays an important role in gas distribution and electrical conductivity. Heat conduction, drainage, etc. Finding graphite materials with excellent performance is an important issue for the industrialization of fuel cells.
In order to meet the demand in the field of hydrogen fuel cells, our experts have achieved satisfactory results through research and development. Our high-purity graphite material has the advantages of moderate density, excellent bending strength and durability, and stable quality, and occupies a mainstream position in the field of hydrogen fuel cells.
Collaboration Cases
Our downstream customers use our materials to manufacture ultra-thin graphite bipolar plates, greatly reducing the volume and weight of fuel cell stacks. Our products are exported to countries such as the United States, Canada, Italy, and South Korea, and have become core suppliers in this field.
Graphite anode plates, anode cylinders, and graphite anode rods (also known as graphite positive plates and graphite positive plates) are resistant to high temperatures, have good electrical and thermal conductivity, are easy to process, have good chemical stability, are resistant to acid and alkali corrosion, and have low ash content. They are used for electrolyzing aqueous solutions to produce chlorine and caustic soda, as well as electrolyzing salt solutions to produce alkali. Alternatively, they can be used for electroplating various metal and non-metal carriers. For example, graphite anode plates can be used as conductive anodes for electrolyzing salt solutions to produce caustic soda. They can also be used for wastewater treatment in the chemical, electronic, and textile industries.

Follow Hong Naide Graphite Editor to learn about the three major properties of graphite electrodes?
After the mold factory switches from copper electrodes to graphite electrodes, the first thing to be clear about is how to use graphite materials and consider other related factors. Nowadays, some group based spark machine customers use graphite for electrode discharge machining, which eliminates the processes of mold cavity polishing and chemical polishing but still achieves the expected surface smoothness. Without increasing the time and polishing process, copper electrodes cannot produce such workpieces.
In addition, graphite is classified into different grades, and using appropriate grades of graphite and electrical discharge parameters in specific applications is necessary to achieve ideal machining results. If operators use the same parameters as copper electrodes on a spark machine using graphite electrodes, the results will definitely be disappointing. If the material of the electrode needs to be strictly controlled, graphite electrodes can be set to a non loss state (loss less than 1%) during rough machining, but copper electrodes are not used.

1. The increasing complexity of mold geometry and the diversification of product applications have led to higher requirements for the discharge accuracy of spark machines. The advantages of graphite electrodes are that they are easy to process, have a high discharge machining removal rate, and have low graphite loss. Therefore, some group based spark machine customers have abandoned copper electrodes and switched to graphite electrodes. In addition, some special shaped electrodes cannot be made of copper, but graphite is easier to form, and copper electrodes are heavier and not suitable for processing large electrodes. These factors have led some group based spark machine customers to use graphite electrodes.
2. Graphite electrodes are easier to process and have a significantly faster processing speed than copper electrodes. For example, using milling technology to process graphite is 2-3 times faster than other metal processing and does not require additional manual processing, while copper electrodes require manual grinding. Similarly, if high-speed graphite machining centers are used to manufacture electrodes, the speed will be faster, the efficiency will be higher, and there will be no dust problem. In these machining processes, selecting tools with appropriate hardness and graphite can reduce tool wear and copper damage. If we compare the milling time of graphite electrodes with copper electrodes, graphite is 67% faster than copper electrodes. In general, in electrical discharge machining, using graphite electrodes is 58% faster than using copper electrodes. In this way, processing time is significantly reduced, while manufacturing costs are also reduced.
3. The design of graphite electrodes is different from that of traditional copper electrodes. Many mold factories usually have different reserved amounts for rough and precision machining of copper electrodes, while graphite electrodes use almost the same reserved amount, which reduces the number of CAD/CAM and machine processing times. This alone is enough to greatly improve the accuracy of mold cavities.
