In addition, under the trend of pure electric platformization of car enterprises, Yang Hong’s new introduction, for pure electric platformization, honeycomb energy development has developed a new standard dimensional battery and large module, and monomer energy density is 245Wh / kg. On the PACK, it can be adjusted according to the model of the model, the expansion is extremely strong, and the whole vehicle can cover the A0 to D-stage sedan, SUV, MPV, etc.

, and the mileage coverage 400-600KM. At present, the product has begun to contact international domestic mainstream car companies, and will achieve batch supply in the future..

The three major applications of the “Black Technology” honeycomb energy lithium battery products after the “Black Times”, all of which are based on laminated processes based on laminated processes.. In this regard, the judgment of honeycomb energy is that the technology direction of the power lithium battery will fully open the “stacking era”.

It has been judged that it is not the “special alone” of a company in a honeycomb energy, and the industry’s consistent consensus is that whether it is a soft bag or a square aluminum shell power lithium battery, due to the design of new energy vehicle battery pack design, its form It is developing towards longer in length, and the high direction is unified at 100mm.. Under this trend, the conventional winding modulation cell has not satisfied the morphological requirements of the vehicle-regulation power cell, which is replaced by the battery cell produced by the laminated process.

Since the laminated battery is flexible, not wound The limitation of the needle structure, the laminated manner is produced, the interface is high in the interface, and it will be widely used in the field of the vehicle rule-level power battery.. Based on this, including Panasonic, Samsung SDI, CATL and other industrial head companies have plans to introduce laminated processes after 2022, and the product of this honeycomb energy is announced, and the signal released is that it has broken through the laminated process.

Bottleneck facing during the actual manufacturing process. A reality that must be faced is that although the laminated process is significantly higher than the performance of the power lithium battery performance, the reality problem in front of the industrial chain company is to be subject to the bottleneck and lamination process of equipment, process, manufacturing, efficiency, etc. There are also many problems in the actual industrial application, which also has become the impede of the development of the dynamic lithium battery industry.

. The first thing is the productivity of the laminated process. At present, the efficiency of the domestic motivation laminated machine industry is generally at 1-1.

2s / piece / single-station, the single-timing efficiency is low, and the manufacturing cost is high.. In the context of mass production manufacturing of power lithium batteries, this has become the largest obstacle to the large amount of lamination process.

. In response to this pain point, the honeycomb energy hires senior laminated equipment and craft experts at home and abroad, in which the industry has completed the development and import of the industry’s first 45-degree rotating high-speed laminate, laminated efficiency It can reach 0.6s / PCS / single-station, laminated efficiency exceeds 40% of single-timing efficiency of industry conventional laminate equipment, and the auxiliary time is shortened from the original 10 seconds to 7.

5 seconds.. At the same time, the honeycomb laminating equipment development technology team is also in combination with excellent lamination equipment at home and abroad, developing a higher speed laminated equipment, as of now, 0.

45s / PCS / single lamination speed verification and prototype development, 2023 is expected to achieve 0.25s / PCS / single lamination equipment development. Further, the use of the vehicle power lithium battery is used in parallel, and the consistency of the monomer cell is higher, so it is more stringent in process control.

. In response to this, the honeycomb energy battery line production line is fully improved control level in the production line construction, environmental control, the key product parameters control, process engineering capacity control, online SPC control, etc., ensuring product quality.

Yang Hong’s new introduction, “through the upgrading of process technology, the production process is high, the strict control of the production process, the honeycomb energy allows the technical efficiency of the laminated film no longer becomes a bottleneck, allowing the high-speed laminated process to mass production into reality. “The performance advantage of the laminate is already the industry consensus. As the equipment technology route is upgraded, the price based on the laminated process will continue to decline, and the promotion of the company represented by the honeycomb energy, the dynamic lithium battery industry” stacking “Will fully open.
