Diversified lithium breakout new energy industry, which is about to meet the industrial expansion.

Lithium looks similar to some ordinary powdered carbon black powder, which is difficult for people to connect them with more and more new energy electric cars on the road. As a matter of fact, Qingdao multivariate Lithium Industry Co., LTD. black powder is the anode material of electric car lithium ion power battery. Their performance has an important influence on power battery.

Qingdao multivariate Lithium Industry company team deep ten years in the industry, for the first time in the world lithium battery with micron grade single crystal of the industrialization of the cathode material, has opened up a technical route of the anode materials industry. Located in Pingdu Dowa high-tech zone of multivariate Lithium Industry company's expansion of large-scale industrialization base of the team, and will drive the Qingdao to become domestic new energy power battery industry an important role in the car.

Technical path

"The naked eye, we produce the positive materials and corporate America, Japan and the anode materials do not have a too big difference, but if you look at their SEM photos will find that they are the completely different material shape." Qingdao multivariate Lithium Industry co., LTD., head of the national "one thousand projects" overseas Sun Yucheng distinguished experts said.

Qingdao multivariate Lithium Industry company mainly in the production of new energy vehicles power battery with nickel, cobalt ternary manganese acid lithium battery anode materials is a kind of micron grade single crystal materials, different from corporate America, Japan, and spherical material.

Sun Yucheng explained: "spherical nickel cobalt manganese acid lithium ternary cathode material in the production process is small particles aggregate technique, and our micron grade single crystal material USES high-temperature sintering process. Image, two kinds of materials, the production process is completely the opposite, spherical material production is a process of polymerization, and micron grade single crystal material production is as far as possible let the precursor of material dispersion at high temperature after single crystal."

Using a high-temperature sintering process in industrial mass production micron grade the positive materials, single crystal Sun Yucheng and his team are the first successful. A different approach, because in his view, the small particles aggregate technology industrialization abroad has been a long time, domestic enterprises is very difficult to have the chance to go beyond. "Rather than follow them, set up their own technical route."

Compared with spherical cathode material, successful industrialization of micron grade single crystal material is its the biggest advantage of better stability, long cycle life. "Spherical material easily is broken when electrode roller pressure, poor processing performance and compaction density is low, easy to flatulence, a direct impact on the performance of power battery." He said.

Though the single crystal materials have become a mainstream domestic anode material enterprises technical route, with the advantages of in synthesis process, the multivariate Lithium Industry company is still in the development of micron grade single crystal technology leading, in the energy density and stability, processability and safe reliability.

To meet industry outbreak

Multiple Lithium Industry companies cover an area of 120 mu, the project construction, with two output will reach 10000 tons, after the completion of the project team is currently have a capacity of 10 times. Since construction began in 2016, the project has been at a rapid speed. At present, the first phase of construction has been finished, the product into the customer validation phase, the construction of phase it is the main body and is expected to be completed at the end of the year can meet production conditions.

Scale and speed of the two elements of multivariate Lithium Industry are short of one cannot, a direct impact on the role of it in the new energy automobile industry in the future. "In the industry before the outbreak of real scale," Chun-Chuan Yang told reporters, head of the project construction, the team predicts that industry will be in 2018 or 2019, and in this important industry nodes, enterprise even if only for a year, is likely to lose first mover advantage.

Since 2013, the new energy vehicles in China under the national policy of aggressive push quickly grow up. But in the past two years, with the relevant national policies, especially the adjustment of the subsidy policy, industry development is about to enter the fully market-oriented phase." New energy vehicles really start to fight performance." Chun-Chuan Yang said, as the key parts of new energy vehicles, power battery must improve the energy density, cycle life important performance indexes, such as the power battery cathode material in the performance of the quality has an important influence on the indicators.

Under the background of the industry, those who blindly spell low-cost enterprises will be eliminated, and the like multiple Lithium Industry real technology companies, has ushered in the golden period of development, they need to expand capacity, access to a larger share of the market, make enterprise scale more on a stage.

In the past, the multivariate Lithium Industry company biggest customer is the nation's largest power battery production enterprises Ningde era. Now, has just completed the first phase of the expansion project has been received, another big power battery domestic enterprises BYD's order, in the future, multivariate Lithium Industry will become the BYD company ternary battery one of the major suppliers of the anode material.

Insist on differentiation to break

According to the performance requirements of the power battery industry constantly improve, the development trend of multivariate Lithium Industry company also iteration path planning in the future industry. And the first choice of technology route of some similar ideas, this time Sun Yucheng also chose a differentiated path. In his view, this also is multivariate Lithium Industry future further to gain a foothold in the industry important advantage.

At present, the industry of nickel cobalt manganese acid lithium ternary feel more consistent view the future direction of the anode material, increase of nickel content in order to improve the capacity of the materials, thereby helping to improve the energy density of power battery, eventually improve the vehicle's range. However, the proportion of the various elements in the material, but have different ideas. Sun Yucheng with mainstream thinking some different ideas, he insists on his own ideas in terms of performance and price, performance and finds a balance between industrialization difficulty of contradictions.

Nickel content in the cathode material, for example, the industry generally are developing a product for nickel account for 80% of the nickel cobalt manganese three kinds of materials, and multiple Lithium Industry companies with the generation of products corresponding nickel proportion were only 70%. Sun Yucheng explained: "the increase of nickel content will reduce the stability of the anode materials, greatly increase the production of power battery is difficult. Battery production itself to the technological requirements is very high, the stability of the material is reduced, the process will be more demanding." In his view, the appropriate to reduce the content of nickel, improve power battery voltage is the more appropriate method." Battery enterprises, improve the battery voltage is not difficult."

Multiple Lithium Industry company's technical strength and constantly expand the scale of the industry, to make it more and more confident insists on differentiation of product line. In cooperation with BYD, multivariate Lithium Industry changed the BYD has always been to nickel 60%, the proportion of various elements in the anode material for power battery enterprises brought a new way of thinking.
