Jin Yinhe refines and strengthens lithium battery electrode manufacturing intelligent equipment actively carries out lithium carbonate layout

At the national two sessions this year, the goal of "carbon peak and carbon neutralization" was included in the government work report, which brought opportunities and challenges to many enterprises.

"carbon peak and carbon neutralization" promotes the green transformation of the global automotive industry, promotes the wave of new energy in the automobile industry, promotes the outbreak of demand in the power battery industry, and releases a large number of demand for lithium-ion equipment. we will promote the innovation and upgrading of intelligent equipment enterprises in products and production processes.

Foshan Jinyinhe Intelligent equipment Co., Ltd. (abbreviated as: Jinyinhe; Stock Code: 300619) products are mainly used in silicone and polymer compounds, lithium battery industry, biochemistry and other fields. The company's lithium power equipment mainly produces battery slurry spiral mixing automatic production line, positive and negative electrode feeding system, mixer, coating machine, roll slitting machine and other lithium battery front stage automation intelligent equipment, it is the first domestic supplier to provide complete solutions for lithium battery electrode manufacturing automation.

The production process of lithium battery is relatively complex, covering the front, middle and back stages. The purpose of the first stage is to process the raw materials into polar slices. The core equipment includes twin-screw slurry production or mixer, coating machine and roll slitting machine, etc., which are related to the product quality of the whole production line. Li Xiaoyun, general manager of Jinyinhe Lithium equipment Division, told Battery Network that the company's lithium equipment revenue accounts for about 50%. As a former equipment manufacturer, the company has been committed to providing the industry with more efficient and energy-saving intelligent and automated equipment. improve the overall quality control rate of products from the aspects of manpower saving, energy consumption operation and cost.

Li Xiaoyun said, for example, Jinyinhe's first lithium battery paste twin-screw continuous automatic production line was used in the lithium power industry in 2013. After nearly seven years of experience, there are 100 lines in normal production, ranking first in the industry.

At the same time, Jin Yinhe also developed and launched a double-sided simultaneous extrusion coating machine suitable for large-scale manufacturing of lithium batteries to solve the problems of quality defects and high cost of the traditional coating machine, and formally mass production and form sales orders in 2020. In the parallel double-sided simultaneous high-speed coating machine, the company adopts combined extrusion coating die and full floating high-speed oven, combined with aerodynamic floating technology and accurate constant tension technology, the process level of AB surface simultaneous high-speed coating and efficient drying has been raised to a new height, the purchasing cost has been reduced by about 10-20%, the operating cost has been reduced by more than 30%, and energy consumption can be saved by 30-40%.

In addition, the company's high-precision bipolar roll slitting and cutting machine integrates the functions of roll press and cutting machine, which can press the pole twice at the same time, solve the problems of pole rebound and polar surface overpressure, and improve the compaction density of the pole. to solve the extension caused by high pressure rolling pole, in a real sense, solve the wrinkling problem of high-speed stripe rolling empty foil area, which can improve production efficiency and reduce comprehensive cost.

"the company's lithium equipment market share continues to increase, full of orders, mainly Guoxuan Hi-Tech, Penghui Energy, Nandu Power supply, Ruipu Energy, Xingheng Power supply, Fujian Giant Power and other power battery customers." Li Xiaoyun said that the equipment competition in the front section of lithium power is fierce, and the company will focus on improving and strengthening the front section, constantly innovating, improving the equipment manufacturing methods in all aspects such as new structure design, processing and assembly accuracy, and using advanced technology to enhance market competitiveness.

In addition to the field of lithium equipment, Jinyinhe is also actively adding to the layout of the field of lithium raw materials.

In 2018, Jinyinhe invested in the project of comprehensive utilization of battery-grade lithium carbonate and high value-added by-products from lithium mica through its wholly-owned subsidiary Jiang Xi'an Deli High and New Technology Co., Ltd. (phase I). It is estimated that the production capacity of lithium carbonate in this project is 6000 tons. At present, Andre's lithium mica lithium extraction project is in the stage of trial operation.

On February 5 this year, in order to better develop the field of lithium extraction from lithium mica, Andre, a wholly-owned subsidiary of Jinyinhe, invested with its own funds to set up a wholly-owned subsidiary Jiangxi Jinde Lithium New Energy Technology Co., Ltd., with a registered capital of 50 million yuan.

Taking advantage of the development wave of the "14th five-year Plan", the Golden Galaxy, which has outstanding product power and R & D reserves, and with the layout of "equipment and materials", will rise abruptly based on its accumulated strength and drive into the fast lane of development.
