Brief introduction of Corey technology to break through the lithium-ion battery technology

The lithium-powered company, which has a reputation for keeping a low profile in the lithium-powered world, made a big move at the 2018 CIBF Battery Show.

At the exhibition, Shenzhen Corey Technology Co., Ltd.(hereinafter referred to as "Corey Technology") mainly exhibited two types of equipment: winding machine and soft package vacuum sealing machine. Among them, the winding machine introduced by Cory Technology attracted many attention.

According to Cory technical field technicians, the winding speed of this winding machine ≥ 2m/s, high-speed operation, winding alignment can still reach ± 0.3 mm.

In 2018, Corey Technology's focus on the lithium market is to focus on key products and strengthen accumulation and precipitation technologies. Winding machine is the company's current focus on the development of a product.

Corey Technology was established in Shenzhen, China in 2001 and has accumulated 17 years of industry experience so far. The Group is headquartered in Shenzhen and has seven precision automation and related businesses. Its business scope spans mobile communications, new energy, medical, hard disk, automotive, logistics and other fields, and maintains in-depth cooperation with industry leaders from all walks of life.

At present, the heavy weight products of Corey technology in the lithium electricity market mainly include stacking machines, soft package vacuum sealing machines, and pressure molding machines. In view of the current market pattern in the front segment of the lithium equipment market is relatively stable, and the competition in the latter segment is fierce. However, there is still a need for process upgrading in the middle segment automation. Corey technology has formulated a "5 + intelligent" fixed-point breakout strategy on the basis of its middle segment equipment field.

Corey's strategy to break through the lithium battery market strategy is to adhere to the 7-word rumor: "do something, do something." Specifically, based on the existing lithium battery equipment market environment and the power battery industry background, Corey Technology will focus on the five core stations in the middle and the back stage, and build core competitiveness through these stations, and strive to become the middle and the back. An integrated solution provider for segment lithium battery equipment.

The first core position targeted by Cory Technology is the roll winding machine and stacking machine for square aluminum shells.

The previously mentioned Corey technology's winding line speed reached ≥ 2m/s. In fact, this device is also characterized by: winding tension real-time measurement monitoring, tension fluctuation ≤ ± 5 %. The most special design is the polar film and the diaphragm are completely isolated and closed. The precision control system with closed loop and low tension is used to ensure the accuracy and consistency of the polar film alignment under high-speed winding operation.

The stacking machine is a boxing product of Corey technology. The biggest feature is the integration of die cutting stacks. Corrie technology laminators are mainly used for square aluminum shells and soft lithium batteries, which can stack multiple cores at once, and the core and the core are separated by gaskets; Can realize the real time correction of the electrode and diaphragm. At the same time, the hardware die-cutting process is adopted to produce the film. At the same time, the offset value of the stack is automatically judged through online detection equipment, and the offset of the stack is automatically corrected. The single machine production capacity reaches 3.5 ppm.

The second core position is a pressure molding machine, including cold pressure and hot pressure. Corey's pressure molding machine is used for naked core pressure molding. It also has Hi-pot testing, Polar ear dislocation detection, information tracing, and NG product removal. The main features are: the pressure plate adopts anti-adhesion treatment, prevents the naked core from sticking to the pressure plate, and has two types of pressurized work positions, one layer and two layers. The parallelism of the upper and lower plates is controlled at ± 0.1 mm, and the temperature of the pressure plates is uniform at each point. The temperature difference ≤ ± 2 °C.

The third core position is Bao Mylar. Corey Technology's package Mylar machine has a stand-alone production capacity of up to 6 ppm, and Mylar and primer tablets can have a replenishment interval of up to 1 hour.

The fourth core position is the measurement machine. Cory Technology's device has two types of contact and non-contact measurements, with core dust removal and DMC marking functions. And can measure the width of the core, the height of the pole column, the height of the pole column, the thickness, the degree of concave and convex, and the parallelism of the pole column.

The fifth core position is to become a component. Corrie's technology design has a capacity of ≥ 15 ppm. At present, Corey Technology has developed a small batch of customer applications for the development of the components.

At present, with many years of industry reputation and focus on the strategy, Corey technology in the above core jobs have reached cooperation with domestic and foreign lithium battery giants. With the gradual advancement of the follow-up market, Cory technology will go to a higher level.
