The appraisal committee agreed that the project is highly innovative and the overall technology is at the international advanced level, among which the continuous winding technology of the separator is at the international leading level, and it‘s agreed to pass the appraisal of scientific and technological achievements.

On June 24, 2022, organized by the Guangdong Mechanical Engineering Society, a scientific and technological achievement appraisal meeting of the project "Research and Development of Continuous Separator High-speed Intelligent Winding Machine for Lithium-ion Battery " completed by Shenzhen Geesun Intelligent Technology Co., Ltd. was held in Shenzhen.

The conference was held both offline and online. Top experts in the industry conducted the scientific and technological achievements appraisal around the continuous separator high-speed intelligent winding machine. The main participating experts are:

At the appraisal meeting, the appraisal committee (online and offline) represented by Academician Chen Liquan listened to the summary report of the technical research and development work of the project completion unit, inspected the production site, watched the application video, and reviewed the submitted relevant materials.

After questioning and discussion, the following appraisal opinions were formed:

01、The project realizes continuous winding during the stations switching through chase cutting, vacuum adsorption, etc., and the production efficiency is increased to 5.7PPM (electrode length：16 meters);

The automatic tab dislocation adjustment function is realized through the automatic diameter-changing mandrel winding, which realizes the intelligent winding and improves the qualified rate of the battery cell;

By optimizing the process flow and simplifying the operation steps, the rapid and accurate winding production of the battery cell is realized, the operation and maintenance time is reduced, and the manufacturing quality of the battery cell and the utilization rate of the equipment are improved.

02、During the implementation of the project, 6 invention patents were applied (1 authorized), 3 utility model patents were authorized, also participated in the formulation of 1 of each national, industrial and enterprise standards, the project demonstrated strong innovation.

03、The product has been tested by Weikai Testing Technology Co., Ltd., all tested items meet the requirements of relevant standards.

After used by the user, we received good feedback, and significant economic and social benefits have been achieved.
