In recent years, Honeycomb Energy has worked hard to build a “foundation”, and technological hard power is the key. The power battery industry is a technology-intensive industry, and a core indicator for maintaining competitiveness is the company’s R&D strength. On November 2, Honeycomb Energy officially announced that the third-generation high-speed lamination technology independently developed by itself has been successfully mass-produced.
The brand-new lamination technology integrates thermal compounding of pole pieces and multi-piece lamination fusion technology, and has achieved a disruptive breakthrough in lamination efficiency, reaching 0.125 seconds/piece, which is more than 200% higher than the second-generation efficiency. At the same time, the equipment unit accounts for The floor area has been reduced by more than 40% year-on-year, and the product safety is better and the production yield rate is higher.
Honeycomb Energy’s third-generation high-speed lamination technology integrates the functions of pole piece unwinding, cutting, lamination CCD online monitoring, and hot pressing, which shortens the transfer of the pole piece from the coil to the lamination, and reduces the cost of pole piece cutting. The processing accuracy between cutting and stacking is poor, which greatly improves the yield rate. The highly integrated third-generation high-speed lamination technology also adopts the timely hot-pressing process after lamination to ensure that the pole pieces of the pole group are in a stable bonding state after hot-pressing, reducing the risk of misalignment caused by subsequent processes, and greatly improving the yield rate. It also reduces product safety risks. At the same time, the online monitoring of the laminated CCD is added to ensure real-time monitoring and elimination of poor alignment during the lamination process, which greatly improves the product defect detection capability and further improves product safety. In terms of stacking efficiency, the third-generation technology, which combines multi-knife cutting and multi-chip stacking technology, has increased the efficiency by more than 200% compared with the second-generation technology, while the equipment unit footprint has decreased by more than 40% year-on-year.
Compared with the winding structure of the pole piece inside the traditional battery, the laminated structure makes the internal space of the battery more fully utilized, has higher energy density, better safety, and is more in line with the needs of the future development of electric vehicles. less efficient. Honeycomb Energy has insight into the development trend of the industry and overcomes the efficiency problem through technological innovation. In 2019, it took the lead in introducing high-speed stacking technology in the production of square batteries, which opened the era of power battery stacking. At that time, it adopted a 45-degree rotating high-speed stacking process to achieve simplex Bit lamination efficiency is 0.6 seconds/piece. Since then, Honeycomb Energy has always insisted on innovative research and development, and promoted the continuous upgrading of high-speed lamination technology. In 2020, Honeycomb Energy innovatively launched the high-speed lamination process 2.0, which has a single-station lamination efficiency of 0.45 seconds/sheet and simultaneously stacks two sheets, so that the production efficiency of laminated batteries can be rapidly improved. Today, the successful mass production of the third-generation high-speed lamination technology of 0.125 seconds/piece not only marks the success of Honeycomb Energy’s technological innovation, but also means that the power battery has achieved another technological leap in its development path.
The continuous explosive growth of sales in the electric vehicle market has driven the demand for power batteries, the heart of electric vehicles, to rapidly move towards the TWh era, and at the same time, the requirements for battery quality have also increased significantly. Honeycomb Energy’s third-generation high-speed lamination technology is at the international leading level in terms of manufacturing efficiency and safety improvement, and it has been planned to be applied to Honeycomb Energy’s mass production line, and it can be quickly scaled up in the future. With the large-scale application of the third-generation high-speed stacking technology, the lithium battery industry will also accelerate into the “stacking era” to better meet the demand for TWh-level power batteries in the future new energy market.
As an indispensable member of the new energy vehicle industry chain, Honeycomb Energy has been closely following market changes and adjusting its approach, thus achieving rapid development and blazing a path of independent development with its own characteristics. As the first battery company to introduce the high-speed lamination process into the production of prismatic batteries, the mass production of the third-generation high-speed lamination technology of Honeycomb Energy will lead the power battery industry to accelerate into the era of lamination.
