Recently, the Yiwei lithium-energy square aluminum shell ternary battery project and the cylindrical lithium-manganese battery project production line were officially put into operation in Jingmen, Hubei, with an annual production capacity of 1.5GWh and 150 million respectively. At this point, the total annual production capacity of Yiwei Lithium-powered lithium battery is 9GWh, including square iron lithium 2.5GWh, cylindrical ternary 3.5Gwh, soft package ternary 1.5GWh, square ternary 1.5GWh, forming a full range of power battery products. , can provide a comprehensive solution for power batteries.
Battery China Network has learned that Yiwei Lithium has developed rapidly in recent years, and the installed capacity of domestic power battery companies has increased from the 16th in 2016 to the 8th in 2017. According to the statistics of the Research Department of the Power Battery Application Branch of the China Chemical and Physical Power Industry Association, the installed capacity of Yiwei Lithium Energy in April 2018 has jumped to the fifth place in the industry. Liu Jincheng, chairman and president of Yiwei Lithium, said that the rapid development of the company is mainly due to the gradual recognition of the quality and supply capacity of Yiwei Lithium Energy Products. The goal of Yiwei Lithium Energy is to achieve the top three in the industry in 2019. .
Three years of stride to write the miracle of "Yiwei Lithium Energy Speed"
“Pursuing excellence, quality first, and creating value” is one of the core values of Yiwei Lithium Energy. In today's great era of builders and creators, Yiwei Lithium can rely on technology-led, innovation-driven development concepts. In recent years, it has achieved great strides and leap-forward development, and has become a shining star in the industry. Liu Jincheng said that the company’s expansion and construction has been in the “going time” for the past three years.
On July 20, 2016, Phase I and Phase II projects of Hubei Jinquan New Material energy storage Power Battery Production Base, a wholly-owned subsidiary of Yiwei Lithium Energy Co., Ltd., were officially put into operation in Jingmen, and the construction of Phase III and Phase IV projects was started at the same time. On June 28, 2017, Yiwei Lithium built China's first 21700 cylindrical ternary battery production line in Jinquan, Hubei Province, which created a milestone in China's battery industry. China's cylindrical battery began to move toward the 21700 era.
Tesla CEO Musk said that the energy density of the 21700 battery is currently the highest in the world's mass-produced power battery.
Yuan Zhongzhi, vice president and chief technology officer of Yiwei Lithium Energy, also believes that to achieve the technical direction of power cell single-cell energy density greater than 250Wh/Kg, the material system will move toward high nickel-silicon carbon system under current technical conditions. Compared with the 18650 battery, the capacity of the 21700 battery is increased by 50%, the energy density is increased by 7~10%, the number of groups is reduced by 30%~35%, and the energy efficiency is increased by about 5%. From a cost perspective, the 21700 battery is lower than the 18650 battery at the same energy density of the power battery module.
On April 10, 2018, Yiwei Lithium Energy Co., Ltd., an annual output of 1.5GWh soft pack ternary battery project, was officially put into operation in Huizhou, Guangdong. It is understood that the energy density of the soft-packed ternary battery produced by Yiwei Lithium can reach 240Wh/kg, the system energy density reaches 160Wh/kg, the discharge rate can reach 4C, and it can meet the high temperature storage and has good low temperature charge. Discharge capacity; single cell cycle life can reach more than 2500 times; also showed good safety in overcharge experiments.
As Liu Jincheng said, in the past three years, Yiwei Lithium has been expanding. At present, the multi-production line layout of power batteries has been completed. The construction efficiency and efficiency cannot help but make the whole industry look at each other. The “Yiwei Lithium Energy Speed” also shows Yiwei Li can be a resolute and pragmatic spirit of seeking truth and being pragmatic.
Science and technology innovation ignites the rapid development engine of enterprises
Scientific and technological innovation is an important driving force for the development of enterprises. The rapid development of Yiwei Lithium Energy is inseparable from its strong technical support. For a long time, Yiwei Lithium has adhered to the strategy of “leading technology and steady development” and has now become a smart manufacturing demonstration enterprise of the Ministry of Industry and Information Technology and a national intellectual property advantage enterprise.
It is understood that Yiwei Lithium Energy currently has a research and development center of about 50,000 square meters. It is equipped with high-tech R&D test instruments and has established a series of laboratories such as electrical performance and safety performance. In 2017, Yiwei Lithium Energy Enterprise Research Institute built a “National Enterprise Technology Center” with a postdoctoral workstation. It currently has 20 doctors, 135 masters, and more than 500 materials, electrochemistry, structural design and electronic circuit design. Full-time R&D personnel form a team of interdisciplinary integrated R&D engineers. At the same time, they also have a team of professional technical consultants composed of academicians of the two academies and experts at home and abroad.
According to the battery China network, Yiwei Lithium's annual investment in research and development accounted for 8% of the total revenue of the year. At present, the company has applied for 920 national patents, of which three invention patents have won the “China Patent Excellence Award” granted by the State Intellectual Property Office, and its innovative products have won the “Guangdong Science and Technology Award First Prize” twice. Liu Jincheng introduced that Li Wei lithium can obtain the first prize of lithium / thionyl chloride battery, and now ranks first in the world in sales of similar products; another battery capacitor product that won the first prize, the same global production and sales before.
“Currently, our products, technology and production are in a leading position in the world. The 18650 battery that was put into production has already received orders from the world's largest power tool company.” Liu Jincheng said, “At the time, the customer mentioned the person who invited the Yiwei Lithium team. Stay and say that you want to see what the first person in the Chinese company got the TTI order. I think this is an industry miracle created by the colleagues of Yiwei Lithium. The production of 18650 batteries has been more than ten in China. In the history of the year, Yiwei Lithium is the newcomer, and the first one has won the order of the world's largest power tool company."
Yiwei Lithium Energy has become a new force in the rapid development of China's new energy power battery industry. Liu Jincheng introduced to the battery China network. So far, the company has built four plant bases in Huizhou, Guangdong and Jingmen, Hubei, and the fifth and sixth phases of the project are under construction. After completion, the company will have an annual production capacity of 11GWh. A tens of billions of new energy power battery industry circle is about to take shape.
For the future, Liu Jincheng said that the vision of Yiwei Lithium Energy is “to be the best lithium battery in the world and to become a leading company in the industry”. Yiwei Lithium Energy is committed to providing high-reliability lithium batteries for the society and bringing China's Lithium batteries are world-leading.
