On May 8, 2022, Tiannai Technology issued an announcement on the plan to sign the "Project Investment Agreement" and invest in the establishment of a subsidiary. The company plans to invest about 3 billion yuan to build the Tiannai Technology West Base Project in Pengzhou City, which is under the jurisdiction of Chengdu City, Sichuan Province. This project will build a carbon nanotube and related composite product production project and Tiannai Technology Chengdu R&D Center.

The first phase of the production project and the R&D center have an investment of about 1 billion yuan in fixed assets. The construction is divided into two phases: the first phase is planned to build an annual output of 5,000 tons of multi-walled carbon nanotubes and 800 tons of hydrogen (by-product); Produce 5,000 tons of multi-wall carbon nanotubes and 800 tons of hydrogen (by-product). Chengdu R&D Center mainly conducts research and development of carbon nanotubes in the semiconductor field and other diversified application fields. The investment in fixed assets of the second phase is about 2 billion yuan, and it is planned to build a production project with an annual output of 10,000 tons of carbon nanotubes and related composite products.

According to the data, the main products of Tiannai Technology include carbon nanotube powder, carbon nanotube conductive paste, graphene composite conductive paste, carbon nanotube conductive masterbatch, etc. In the field of power lithium batteries, the common practice of enterprises is to add carbon nanotubes to the positive electrode material as a conductive agent to improve the conductivity of lithium batteries, increase the energy density of lithium batteries and improve the cycle life of lithium batteries.

With the growing demand for high-quality batteries in the power battery market, carbon nanotubes have been widely used by lithium battery manufacturers as a new type of conductive agent due to their superior electrical conductivity, gradually replacing traditional conductive agents to improve their energy density. , fast charge and fast discharge, cycle life and other performance. In the field of positive electrodes, companies add carbon nanotubes to positive electrode materials as conductive agents to improve the conductivity of lithium batteries, increase the energy density of lithium batteries, and improve the cycle life of lithium batteries. In addition, in the field of anodes, as the technology of major material companies becomes more and more perfect, and the application technology of related battery companies gradually matures, the application of silicon-based anodes will gradually increase. However, the conductivity of silicon-based anodes is worse than that of graphite-based anode materials such as natural graphite and artificial graphite, so carbon nanotubes and other materials need to be added to improve their conductivity.

After the project is put into production, the production capacity of Tiannai Technology's main business products will be expanded, which will help the company reduce costs and increase efficiency and improve its sustainable profitability. The company has built a stable market system and good brand influence, which is conducive to the market promotion and sales of the products of this investment project, continues to increase the market share of the company's products, and enhances the company's business scale and core competitiveness, which is in line with the company's long-term development plan.
