Lithium-electric "Davos" Forum/Battery 100 People's Assembly Secretary General and Founder / Chairman of Battery Network Yuqingjiao said, The survey was conducted by the Zhongguancun New Battery Technology Innovation Alliance, the Battery 100 People's Meeting(Micro number: CBHA100), the Lithium Power "Davos" Organizing Committee, Battery Network(Micro number: mybattery), and I Love Tram Network(Micro number: xevcar). This research activity is supported by big group laser technology industry group limited company. The purpose of the activity is to conduct system research on industrial chain enterprises such as lithium batteries and materials, new energy vehicles, energy storage, and lithium-related equipment in Shandong Province in 2018, to thoroughly understand the industrial layout and future development direction of enterprises, and to propose the status quo of enterprises and existing problems. Resource integration, capital docking and other recommendations; Promote the promotion of the brand image of research enterprises(listed companies) and the promotion of product cooperation between enterprises and enterprises; Through research reports and data analysis. Restore industry truth, feedback industry voice, report typical cases, spread positive energy.

On the morning of the 24th, the research team and its party came to Jining City Unbounded Technology Co., Ltd.(abbreviation: "Unbounded Technology"), visited the company's R&D technology center, etc., and conducted exchanges and talks with the company's management.

Unbounded Technology was established in May 2004 and is a state-level high-tech company specializing in the research and development, production and sales of lithium ion battery cathode materials. The company now has a production capacity of 200 tons per month. To meet market demand, the company is currently seeking cooperation in many ways and plans to add 1,000 tons of production capacity during the year. It is expected that production capacity will reach 8,000 tons in the next three years.

Unbounded science and technology, relying on its own scientific research capabilities and innovative mechanisms, has developed into the most complete variety of lithium-ion battery cathode materials and the most professional cathode materials professional supplier. The company has a complete innovation mechanism and service system, has established municipal enterprise technology center, municipal lithium battery material engineering research center and Shandong province lithium battery positive material engineering research center. A high-level R&D team composed of doctoral, master's, senior engineering, and engineers has been established with a reasonable professional technical structure. The R&D team has been repeatedly rated as an "excellent scientific and technological innovation team" by Jining City and High-tech Zone, and the team leader has been awarded the "Holy Land Scholar". Special experts "title. While mastering the existing positive materials technology, the self-owned R&D technology center can adjust the R&D direction at any time according to the changes in the industry and market, and play a guiding and leading role in the product technology and process for downstream customers.

Unbounded technology has completed the industrialization of more than a dozen products such as lithium cobalt acid, lithium manganese acid, lithium Gaodianya, lithium nickel cobalt manganese acid, and lithium ferrous phosphate, demonstrating the strength of product industrialization. Since the product was listed in 2007, the stability of product quality has been well known in the industry. The advantage of the product is that the comprehensive performance is superior: that is, the high cycle life is achieved under the premise of ensuring high capacity and high voltage. Product indicators and production stability in the industry at the leading level, with a strong competitive advantage.

"Unbounded Technology uses lithium manganate, ternary materials, and lithium ferrophosphate as the core of development, and pioneered the 5V binary material. At present, the company's high-nickel positive material has entered the pilot stage. Next, the company will actively conceive manganese based sodium ion batteries. Positive material development direction. The company launched new products 622 and 811 in the area of lithium nickel-cobalt manganese acid in 2017. Among them, 622 uses oxide surface coating technology to improve the compatibility of materials with conventional electrolytes and greatly improve the safety performance and recycling performance. 25 ± 2 °C Semi-battery constant temperature test 0.2 C charge discharge(3.0-4 .3 V) ratio capacity is greater than 177 mAh/g, the full battery 1C charge and discharge 1000 cycle capacity remains more than 80 <UNK>; Lithium nickel-cobalt manganate 811 uses sedimentary coating technology to synthesize high-capacity high-nickel oxides, and the shell coating is a composite material with good stability and low nickel oxides. 25 ± 2 °C Semi-battery constant temperature test 0.1 C charge and discharge(3.0-4 .3 V) carbi capacity greater than 190 mAh/g.

The company plans to launch two new lithium manganate products this year. The new products use high-purity, low-impurity raw materials, elemental doping technology and surface coating technology to improve the comprehensive performance of lithium manganate. Among them, the capacity type WJ-2700 has a capacity of up to 130mAh/g(lithium sheet), which is 10-15mAh/g higher than the current market capacity type; The dynamic type WJ-2600 pursues high magnification and high cycle, making a perfect large monocrystalline octahedral structure. The 10c magnification will reach more than 95 % and the cycle will be more than 2000 weeks.

Chief Engineer Lijunfeng also revealed to the research team that the company's future research and development direction:(I) In terms of positive polar materials, the development direction of nanon positive polar materials is expected to have a capacity of 0.2 C greater than 240mAh/g(2.0 ~ 4.8 V). (2) In the development of lithium batteries, the development of lithium nickel manganese acid is used in the field of power batteries, and will give full play to its advantages in Gaodianya, high safety, high magnification, long cycle life, and high temperature cycle performance; The application of lithium-rich manganese base in lithium-ion batteries will improve energy density and reduce cost.

The chairman said that unbounded technology positioning in the high-end market, since its establishment, has been committed to R&D, has a core technology team, and then the company will actively seek multilateral cooperation to expand the scale, driven by the development of positive materials, to the lithium industry diversified development. The company adheres to the combination of innovation drive and brand management, and based on the development of the company into a high-tech enterprise with strong international competitiveness and sustainable development, it has become a power lithium battery overall solution provider.
