Recently, the Qionglai sub-venue of the on-site promotion of major projects in the first quarter of 2023 in Chengdu, Sichuan Province was held in the functional area of semiconductor materials industry in Tianfu New Area, Qionglai City. This activity launched 26 construction projects with a total planned investment of 16.3 billion yuan.

Among them, the three new energy projects of Putai battery were started on the same day, covering the construction of diaphragm, anode and lithium battery equipment, with a total investment of 8.6 billion yuan.

Specifically, the second phase of the base film and coating integration project of Sichuan Zhuoqin New Material Technology Co., Ltd., with a total investment of 6 billion yuan, covers an area of about 283300 m2, and a building area of about 177000 m2. It will build a base film coating integration project with an annual output of 960 million square meters, a lithium ion battery diaphragm production line with an annual output of 840 million square meters, and a lithium ion battery coating diaphragm processing production line with an annual output of 4.98 billion square meters.

The diaphragm base membrane production line in this project is the world's broadest production line, and is the exclusive supplier of Ningde Times. After the completion of the project, the annual output value will not be less than 3.3 billion yuan.

The second phase of the negative electrode and graphite integration project of Sichuan Zichen Technology Co., Ltd. has a total investment of 2 billion yuan and a total construction area of 140200 m2. This project is matched with the production device with an annual output of 100000 tons of negative electrode materials, forming an integrated construction project with an annual output of 100000 tons of high-performance lithium-ion battery negative electrode materials.

When the first and second phases of the project are completed and put into operation, it will meet the demand of about 70% of the contracted power battery capacity in Chengdu, and the annual output value will not be less than 10 billion yuan.

The lithium battery intelligent equipment manufacturing and construction project of Sichuan Jiatuo Intelligent Equipment Co., Ltd., with a total investment of 600 million yuan and a total construction area of 152000 m2, will build a production base for high-speed extrusion coater, diaphragm coater and base film lifting line equipment. The project will fill the gap in the domestic diaphragm coating equipment localization and become an important support for the domestic new energy automobile industry. The project will reach its completion and production capacity, with an annual output value of not less than 1 billion yuan.Editor/Ma Xue
