From May 16 to 18, the three-day 15th China International Battery Technology Exchange Conference/Exhibition (CIBF2023) came to a successful end in Shenzhen World Exhibition&Convention Center. In a short three-day exhibition period, there were a continuous stream of visitors. This exhibition attracted more than 360000 visitors from home and abroad, the highest number in the past years.

At this exhibition, Xinyuren brought the "Single direction double-sided coating Machine" with them for the first time, attracting a large number of lithium battery practitioners to visit, consult, and communicate at the booth. This equipment has also become a major highlight of this lithium battery coating equipment and has been recognized by many lithium battery practitioners!

Advantage 1: Thoroughly solve the problem of affecting the alignment of both sides due to the shrinkage of one side of the electrode during drying when multiple coatings are applied

The SDC coating machine directly applies the B surface without drying after the A surface is coated, effectively preventing the occurrence of large alignment errors between A and B surfaces caused by the shrinkage of the electrode plates such as hot supply.

Advantage 2: The pole piece does not curl, crack, and leave white without wrinkles

The first 1/3 box of the equipment adopts patented heating with electrode opening, and the high capacity design can also discharge at high rates; Using a single-layer oven to dry both sides at once, the moisture consistency of the electrode is excellent, completely solving the problems of electrode cracking and curling caused by traditional backflow coating and secondary baking. The SDC coated electrode does not curl, and there are no cracks on the surface of the electrode, resulting in good bonding effect; It can achieve a dryness of electrode plates below 500PPM. Compared with traditional technologies, SDC coating significantly improves the performance of the battery (cycle, capacity, self-discharge, internal resistance, etc.).

Advantage 3: Good consistency on A/B side, consistent moisture content on both sides, and consistent peeling strength of active substances on both sides

The coating slurry on the A/B side comes from the same feeding tank; The consistency of the A/B surface slurry is good, the drying frequency of the AB surface is consistent, and the moisture content is consistent. The AB surface is dried simultaneously, and the stress consistency on both sides is good. At the same time, it can reduce the moisture content of the electrode. Based on the above, the A/B surface of the electrode is more uniform and consistent compared to traditional methods.

Advantage 4: Compared with traditional coating machines, it saves more than 30% energy

obvious. Compared to the traditional foldable double-layer coating machine structure design, the single-layer structure design of the Single direction double-sided coating Machine not only saves a lot of costs in manufacturing, but also significantly saves energy consumption by drying both sides of the electrode after coating, with an overall savings of at least 30%.

Transcendental innovation of SDC technology will gradually replace traditional coating technology. The battery industry is booming, and while battery companies are rapidly expanding, their technology is also in a process of rapid iteration and innovation. Only by keeping up with the times and surpassing current technology can the market meet its development needs.

From 2015 to 2021, after 6 years of obtaining numerous invention patents, Xinyuren achieved the goal of becoming something from scratch. After years of in-depth research and development, the actual R&D cost of Single direction double-sided coating Machine exceeded 100 million yuan, and finally produced highly innovative domestic high-end equipment, ushering in a new era of lithium battery coating equipment development.

Our colleagues have always maintained a warm and dedicated service spirit during the exhibition, using their respective expertise to provide detailed product introductions and answer questions for customers who come to the exhibition. At the same time, we also thank many domestic and foreign industry experts, customers, and partners for visiting and exchanging ideas at the Xinyuren booth at this exhibition. We look forward to and also look forward to seeing you again at the next CIBF Battery Exhibition!

Xinyuren believe that science and technology are the primary productive forces. In the future, we will continue to overcome difficulties, innovate continuously, and strive to become a high-tech enterprise in the manufacturing of lithium-ion new energy automation equipment!
