The Yellow River Group, located in Changge City, Henan Province, is mainly engaged in carbon-based materials. With new energy and intelligent manufacturing as its growth point, innovative development ideas and continuous transformation and upgrading have not only brought a “cross-border subversion” to China's new energy market. It also injected new vitality into the development of the local private economy.

Graphite is not produced here, but it has become the world's largest synthetic diamond production base. Graphene is produced from graphite waste after diamond production. Graphene is applied to lithium batteries to increase the specific energy of the battery by more than 30%.

Highly automated production process

The production workshop of Henan Lixuan Technology Co., Ltd. (hereinafter referred to as “Lixuan Technology”), a new energy company under the Yellow River Group, is located here in the Yellow River Industrial Park in the northern section of Weiwu Road, Changge City. Since the production environment of the lithium battery requires constant temperature and drying, the visit passage must be kept clean. I saw the employees wearing anti-static clothing, operating the equipment on the operation screen, and automatically guiding the car to carry the production materials in a busy and orderly manner...

Although the Yellow River Group is located in the mainland, its new energy-powered lithium battery project has been established since April 2016. In terms of talent introduction, equipment selection, process design, and manufacturing processes, it is based on domestic first-class and international leading positioning. development of.

Wang Jian, the project leader and general manager of Lixuan Technology, introduced the concept of the production line, integrated the concept of Industry 4.0, and exchanged and cooperated with advanced lithium battery equipment manufacturers at home and abroad to create the first intelligent factory production line in the industry. In the key processing process, the numerical control rate reaches 90%, and the whole process digital automatic operation is realized on the production line, saving 37% of the personnel.

Nowadays, the second phase production line of lithium batteries, which is under construction, has an area of ​​only 5,000 square meters, but the production capacity is five times that of the first period, and the operating cost can be saved by 15 million yuan per year. The second phase production line is expected to be put into operation at the end of this year.

“The key to the second phase is to improve the intelligent level of material transportation. We use the workstation module to design the production line. The workstations are fully efficient, flexible and intelligent, and complete a series of complicated tasks. The module automation productivity reaches 100. %, the system assembly automation rate can reach more than 96%." Xia Hui, the minister of technology and technology, said that after the automation is improved, the production process is optimized, and the site utilization rate is improved. It can be built in almost the same large site. More production lines have greatly improved production efficiency.

Continuous innovation of scientific and technological talents

According to China's new energy vehicle power battery market research report, in the first five months of this year, the number of soft pack battery installed capacity, Lixuan Technology ranked 15th in the total number of 12,902 kW fashion machines, is the most "young" battery among the 15 battery companies. enterprise.

On May 8 this year, the Chongqing Motor Vehicle Inspection and Inspection Center of the National Motor Vehicle Quality Supervision and Inspection Center reported that the five power battery systems sent by Lixun Technology passed the test and the energy density was as high as 146~150 Wh/kg. Excellent test data and reliable product quality have won the recognition of the market. Shenlong Bus, Ningbo Shipyard, Pinggao Electric and other enterprises in and outside the province have thrown olive branches to Lixuan Technology.

High quality development requires high quality talent. The Yellow River Group adheres to the consistent "people-oriented" scientific development concept, adjusts the talent structure, trains and introduces high-level scientific and technological talents, and builds a team of high-quality scientific and technological talents. At Lixuan Technology, the average age is only 26 years old and 60% is a technical team with a college degree or above and 160 people. It allows journalists to feel the vitality of their innovation and their determination and confidence in the officers, officers, and achievements.

Today, the Yellow River Group has a state-level enterprise technology center and a post-doctoral research station. It is a national high-tech enterprise. It has completed 173 research and development projects, completed 209 new product developments, and owned 586 patents (including 29 invention patents). A large number of core dedicated technologies. “The Sixth Plenary Session of the Tenth Provincial Committee of the Provincial Committee highlighted the high-quality development, which puts higher demands on us. Next, we will continue to develop and continue to surpass the pursuit of new energy benchmarking enterprises through scientific research and innovation and independent development. Keep moving forward," Wang Jian said. 35

The first motivation to activate high quality development

Ren Xiaoli, Director of the Center for Regional Economic Research, Henan Academy of Social Sciences

The high-quality development of the economy emphasizes the improvement of “quality”. It is necessary to put innovation in the core position of the overall development and activate the first impetus for high-quality development. Innovation makes the industry from small to large and from big to strong. The Yellow River Group is a model that dares to innovate and be good at innovation. It seizes the opportunity of technological iteration and enters the new energy field with the atmosphere, from pure diamond production to graphene lithium battery new energy industry chain, and quickly gains a place in the market. Through scientific research and innovation and independent development, the Yellow River Group is gradually forming a development model with innovation as its main leading and supporting, and strives to realize the transformation from manufacturing to creation, speed to quality, and product to brand, thus stimulating the company's vitality and creativity. To enhance the company's core competitiveness and sustainable development capabilities. What is gratifying is that the Yellow River Group is leading the transformation of the province's manufacturing industry into an intelligent one - "equipment replacement", "production change line" and "machine substitution". Automation has realized the standardization of production, and intelligentization can further improve product quality. The “sweat-type economy” is less, and the “smart economy” is more, and new kinetic energy is gestating a vigorous force.
