How to crack the problem of large scale and efficient mass production of energy storage cells?

in News

Under the global "double carbon" consensus, the energy storage market will see explosive growth, which in turn will drive the rapid growth of the energy storage lithium battery market demand.

With the diversification of energy storage application scenarios, the energy storage market has put forward higher requirements for energy storage batteries in terms of product quality, service life, and cost reduction, forcing energy storage battery enterprises to improve product quality and technological innovation.

Behind the improvement of energy storage batteries, quality is inseparable from the cooperation and support of upstream raw materials and production equipment, which in turn puts forward new requirements for material and equipment enterprises.

The large size of energy storage cells is becoming a trend

At present, the screening and secondary utilization of retired power batteries from electric vehicles are considered a direction for the development of the energy storage market. However, the uneven battery quality and complex battery models have become obstacles to the large-scale secondary utilization of retired batteries.

At the same time, the power battery screening down can no longer fully meet the needs of the energy storage market, and high-quality energy storage batteries that meet the energy storage application scenarios will become the mainstream of the market. As the market demand for energy storage continues to expand, the disorderly market competition and different product specifications in the early stage will also gradually move towards standardization with the influence of the market scale effect.

Among them, the energy storage market requirements for battery quality improvement and cost reduction is affecting the direction of battery size development, battery companies generally by making larger cell size to reduce costs become the trend.

For example, the square cell from the previous 50 AH as a multiple of the mainstream products to 280AH upgrade step, the current 280-310AH square battery gradually become the mainstream of large energy storage market applications.

Bell-type equal-pressure liquid injection method becomes the mainstream of technology

It is important to note that the large size of the battery cells and the increase in energy density of the batteries are also increasing the performance requirements of the production equipment.

Domestic mainstream energy storage head battery companies are using higher quality production equipment to produce energy storage batteries. High-quality equipment brings consistency to the newly produced high-quality batteries, which in turn improves their product competitiveness.

Taking liquid injection as an example, the increase in battery energy density and the substantial compression of the internal space at the time of design has brought higher difficulties to liquid injection, and the differential pressure 6PPM turntable and linear liquid injection machine are gradually eliminated from the market.

The 20PPM high-flexibility bell-type isobaric fluid injector developed and produced by Planautis has been used in energy storage battery enterprises on a large scale, which can meet the needs of energy storage battery enterprises with larger cell sizes and improved production efficiency.

Large-scale mass production and cost reduction require continuous upgrading of battery production lines, and the high-flow, high-precision 50PPM bell-type isobaric fluid injector developed by Pinatex has become the technical mainstream of fluid injection for energy storage head battery companies and new large square battery factories.

At the same time, the intelligent series module independently developed by Planautus is integrated bypass board control, achieving constant current and constant voltage charging, realizing active balancing function, with high integration, simple installation, easy maintenance, heat generation MOS≦70℃, etc., for the fully automated component capacity to achieve: high voltage series into, no overshoot constant current and constant voltage function, a variety of batteries quickly change type, fixed asset investment reduction and operating costs significantly Down, in the battery scale production to provide better conditions.

Pinatex focuses on new energy high-end technology and equipment, and is mainly engaged in the R&D, manufacturing, sales, and whole process service of high-efficiency liquid injection and core accessories liquid injection pump, intelligent component capacity, and core accessories parallel and series power supply.

The high-flow high-precision 50PPM bell-type equal-pressure liquid-filling machine developed by Pinatex can significantly improve electrolyte absorption efficiency and infiltration effect, which will empower energy storage battery enterprises to improve production efficiency and product safety performance, and help the energy storage industry to become bigger and stronger.
