The low temperature use of lithium-ion battery has low capacity, serious attenuation, poor cycle rate performance, obvious lithium evolution and lithium removal Imbalance and other problems. However, with the continuous expansion of application fields, the low temperature performance of lithium-ion batteries is restricted More and more obvious. At -20℃, the discharge capacity of lithium-ion batteries is only about 31.5% of that at room temperature. Traditional lithium-ion batteries operate at a temperature of - Between 20 ℃ and +55℃. However, in aerospace, military, electric vehicles and other fields, the battery is required to be between -40°C and 60°C Working normally, high-altitude drones and some special equipment for cold climates can experience electric vehicles as low as -60°C Battery systems capable of stable performance in cold regions and hot desert conditions are needed. Therefore, improve lithium ionization The low temperature property of the cell is of great significance.

Lithium-ion batteries have been introduced into the domestic market since their birth in the 1990s. In the first 10 years, Japan and South Korea's lithium-ion battery production has been an absolute advantage; Since then, China's lithium-ion battery technology has made great progress, and the industrial scale has exceeded Japan and South Korea, becoming the world's largest producer and user of lithium-ion batteries.

In 2022, under the background of dual-carbon, electric vehicles and energy storage industry ushered in the first Never had the opportunity to grow. Total global lithium-ion batteries for electric vehicles and energy storage batteries in 2022 957.7GWh, a year-on-year increase of 70.3%. Automotive power battery 684.2GWh, an increase of 84.4%; Energy storage battery 159.3GWh, an increase of 140.3%; Small battery 114.2GWh, down 8.8% year-on-year. Chinese lithium The output of ion batteries is 660.8GWh, an increase of 97.7%, accounting for the global total 69.0%. In 2022, China's energy storage lithium battery 130GWh, including power storage, household Energy storage and portable energy storage were 92GWh, 25G Wh and 4GWh, respectively, an increase of 216.2%, 354.5% and 207.7%

In recent years, the global lithium battery industry has grown significantly, and in 2022, lithium-ion batteries have exceeded 948.1 GWh, with Moved the positive electrode material development. But currently commercial positive electrodes such as lithium cobaltate (LCO), lithium manganate (LMO), Ternary materials (NCM/NCA) and lithium iron phosphate (LFP) still cannot meet the requirements for higher energy density, Low cost demand.

From March 29 to 30, 2023, the two-day 5th China Lithium Anode Material Technology Innovation and Industrialization Seminar was successfully concluded in Changsha. As the sponsor of this seminar, our company participated in the equipment exhibition of this seminar. Anode and cathode materials are the key materials in lithium-ion battery. Currently, the lower limit of energy density for lithium-ion batteries depends on anode and cathode materials, and anode and cathode materials account for 60% to 70% of the cost of lithium-ion batteries. Therefore, accelerating the research and development of anode and cathode materials and improving the production process will not only improve the comprehensive performance of lithium-ion batteries, but also significantly reduce the high cost of batteries.

On March 27, 2023, the intelligent PECVD system customized by our company for Dongguan People's Hospital (Affiliated Hospital of Southern Medical University) was successfully delivered. PECVD(Plasma Enhanced Chemical Vapor deposition) can produce unique compounds and films that cannot be produced by ordinary CVD technology alone, and produce films with extremely high solvent and corrosion resistance as well as chemical and thermal stability, which are widely used in the semiconductor industry to manufacture integrated circuits and have many applications in photovoltaic, tribology, optics and biomedicine.

On February 22, 2023, the fourth High Specific Energy solid State Battery Key Materials Technology Conference, which lasted for one and a half days, ended successfully in Changzhou, Jiangsu Province. Solid-state battery is recognized as the most promising new generation of battery technology, almost all power battery enterprises and car manufacturers are accelerating the layout, in order to seize the initiative in the solid-state battery era. As the core technology of solid electrolyte and matching anode and cathode materials, is now the major research institutes, enterprise R & D department technology focus. Prof. Tang Yongfu from Yanshan University, Prof. Yuan Hong from Beijing Institute of Technology, Prof. Xiang Yong from University of Electronic Science and Technology of China, Prof. Zhang Tao from Shanghai Institute of Ceramics, Chinese Academy of Sciences and other experts and professors elaborated the latest research results and views of their respective subjects, and seriously answered questions from the audience. As a sponsor of the conference, Nobardi participated in the exhibition of on-site learning and related equipment. Rotary vacuum atmosphere furnaces for solid state battery energy materials with different sintering needs, anti-corrosion box furnaces for glove boxes, and solid state batteries in线压力测试套装等设备，均得到了与会专家的积极关注和咨询，并对我们的设备从设计思路到科学控制均给予了高度评价。 不少科研人员与我们现场沟通了试验过程中遇到的设备问题，并提出了相关的需求方案。部分问题将同步到诺巴迪的技术部门，并及时将结果反馈给客户。 作为专注于实验室热工设备研发的高新技术企业，诺巴迪将通过不断的学习研发，为新材料和新能源技术的发展提供专业的设备及技术方案，为基础科学的研究持续创造价值。
