Wanxin Graphite: It is planned to build an annual output of 10,000 tons of graphene production line

Once upon a time, graphene products in Heilongjiang Province were still on the edge of many pillar industries. It seems that graphene products are not elegant. In recent years, with the rise of emerging industries, Heilongjiang has aimed at the graphene industry and carried out a series of scientific research and development. With the help of the resource advantages of large and medium-sized cities such as Harbin, Jixi, Luobei, and Hegang, it has explored a leap from the Red Sea. Into the "Blue Sea" new path. Scaly graphite is about 3,000 yuan per ton, and processed spherical graphite can be sold to 20,000 yuan. Processed negative material can be sold to more than 100,000 yuan per ton, and pulp can be made to reach 80,000 yuan per ton. If it is converted into powder, It can reach millions per ton. Become a booster to drive Heilongjiang's industrial economic development

Rich in resources, China's graphite production, and sales rank first in the world

Talking about the graphene industry, a member of the national graphite industry science and technology development special planning expert group, professor of Harbin Institute of Technology, the chief expert of Harbin Wanxin Graphite Valley Technology Co., Ltd. Yuan Guohui told reporters that as a raw material of graphene, China's graphite production accounts for the world. 2/3, while Heilongjiang accounts for 2/3 of the country. Heilongjiang is rich in graphite resources, and natural flake graphite is crystalline in terms of traits, but the crystals of flake graphite are large, and each piece can reach millimeters.

From the processing level, the content of earthy graphite crystals reaches 80%, mainly associated with coal, and flake graphite is in stone, and the formation conditions of the two kinds of graphite are different. Soil graphite has a very high carbon content and a high graphite content, but purification is difficult and processing is particularly poor. Therefore, earthy graphite can only do some low-grade products.

Harbin Wanxin Graphite Valley Technology Co., Ltd. uses scale graphite mainly because the primary screening (flotation) is simple. Previously, the scale graphite was sold to several hundred yuan per ton, and now the flotation is probably sold at 1000~3000 yuan/ton. From an international point of view, the production and sales of graphite in China are the first. The graphite used in foreign countries is basically imported from China, and the graphite with good quality is selected. It is an important product for export exchange. Due to the small amount, it is no longer an important exchange product.

High-tech support to create a "wing" that spans development

From the development history, the graphite industry has experienced the following stages of development. The first stage was in the early 1980s, when the United States carbonization company developed expanded graphite (flexible graphite products), and based on this, some columns were created. At that time, the Chinese imported a flexible graphite production line from the United States and Japan, one in Shandong and the other in Hubei. After all domestic graphite deep processing production lines, are based on these two lines from the transformation, so leading to high-end graphite products have not been done well, while ordinary graphite products have been surplus, and consumed a large number of resources.

The second stage is the deep processing industry represented by China Baoan Group and Bethray Company after the appearance of lithium-ion batteries. At that time, natural graphite contained many impurities, and the impurities contained in graphite from different places were different, which would affect lithium ions. Battery performance, so for a period of time, domestic use of graphite as a lithium-ion battery has raised doubts, but with the upgrade of technology, Betray quickly overcome this problem, the lithium-ion battery has also become the number one export product. In 2000, Betray began to pay attention to the graphite resources of Heilongjiang. In 2011, it officially entered Heilongjiang, and began to deep processing graphite. At that time, the scale graphite was about 3,000 yuan a ton, and the processing into spherical graphite could be sold to about 20,000 yuan. The processing into a negative electrode material could be sold to more than 100,000 tons. This is a great shock to the graphite deep processing enterprises. By about 2013, the same graphite(ordinary scale graphite) has been sold from 2,000 to 3,000 yuan/ton to 6,000 to 7,000 yuan/ton. There are few enterprises and there are also some production lines. The volume is very large. However, due to the restrictions of technology and the market, it has not developed. It has always been Beiterui.

The third stage is the graphite deep processing industry led by graphene. Graphene has two major forms. When it is used as a powder, it can be made with natural graphite, and the yield is high. At present, the price of graphite market fluctuates greatly, and the price is about several thousand yuan per ton. However, graphene powder can be greatly increased. In the process of using graphite powder, it needs to be dispersed into different application fields. Because the dispersion process is very difficult, all the graphene powders are made into liquid slurry by Harbin Wanxin Graphite Valley Technology Co., Ltd., and the price per ton can be Up to 80,000 yuan, which greatly increased the added value of the product.

Aiming at the future market to establish a "flag" for leapfrog development

As a graphite deep processing enterprise, we must always aim at the future market and seize the opportunity. Yuan Guohui told reporters that the current global research and development of graphene is concentrated in two fields. One is a thin film graphene, which is a strategic industry. It is an indispensable high-end product for microelectronics in the future. However, the current maturity of thin film graphene technology is not high. It is still difficult to form industrialization. The other is graphene conductive paste, and the market prospect is extremely broad. According to estimates, by 2020, with 500 million electric vehicles as the reference base, only the graphene conductive agent, the market size will reach about 100 million to 200 yuan. From a business perspective, even with a 10% market share, sales are already impressive.

Lithium-ion batteries, first developed by Sony Corporation of Japan, now more than 90% of lithium-ion battery companies are concentrated in China, Japan, South Korea, most of the production is concentrated in China, there is a part in the United States, almost no Europe, so China's graphene The product market, especially Heilongjiang, has a broad development prospect for the graphene industrial base, which is integrated into production and processing. This is one of the reasons why graphene deep processing enterprises have the confidence to promote this industry.

Harbin's geographical location, unique talent, talent reserve, scientific research strength, transportation, industrial support, etc. have great advantages, so Harbin Wanxin Graphite Valley Technology Co., Ltd. chose to drop the graphite valley in Harbin and began preparations for the production line in July 2015. It was officially put into operation on October 16 and has already received orders before entering production and entered the Korean market.

At present, the domestic graphene industry market is becoming more and more mature. With the continuous expansion of market demand, the original production line of 1,000 tons per year can no longer meet the market demand. Therefore, Harbin Wanxin Graphite Valley Technology Co., Ltd. plans to build another production line with an annual output of 10,000 tons. It is expected to be put into production in June 2017 to meet market demand.
