Sodium Carboxymethyl Cellulose For Battery Industry

CMC, with the strong cohesion, good heat stability, electrical conductivity and electrochemistry property, makes the active substance and electrolyte form the even and dispersive paste, and takes the hydrogen bond effect with the silicon, therefore, it is not only widely used as the binder of cathode and anode, gel for cathode protection, but also widely applied in the silicon base electrode and graphite modification.

Application in silicon-based electrode

CMC used in the silicon-based electrode, besides the heat stability, conductivity and electrochemisty, the strong hydrogen bond exists between CMC and silicon. Hydrogen bond has the self-recovery, and it can adjust the stress which continuously enlarge during the circle process of the material and so that it can maintain the stability of the material structure, and keep the capacity over 1000mAh/g during at least 100 times circulation, and the coulombic efficienty reaches 99.9%. CMC which is applied in silicon-based electrode will show the effect as follows:

*With the strong shear-thinning property, CMC can adjust the rheoloty of the slurry;

*Excellent circulation, primitive reversible capacity and better capacity retention;

*Effectively cushion the change of the volume swelling of the silicon-based electrode, and improve the electrode reversibility;

*With the double optimization to mechanics stability and the chemistry stability, CMC promotes to form the SEI film;

* CMC impacts on silicon granule, and reduces the damages for silicon-based electrode volume swelling;

*Effectively inhibit the side-reaction between high reactive Li-Si alloy and electrolyte;

*Use with other gel binders, and enhance the binding strength and activation properties.

Dongying Lingguang New Material Technology Co., Ltd. is a high-tech enterprise that is focusing on research, development, production, and sale of Carboxymethyl Cellulose Sodium(CMC) and Poly Anionic cellulose(PAC). Which is located in Dongying City, Shandong Province. With 230 employees, $23 million asset and an area of 133,400 square meters. Now the capacity has reached 20,000 tons per year, but the third expansion project is starting building, which involves the production of 30,000 tons of green, environmentally friendly, high-end, and efficient Sodium Carboxymethyl Cellulose through comprehensive utilization. The total area covers 70,000 square meters. Total investment $56 million, The construction has begun and scheduled for completion in 2025.

     In addition, we will purchase a new 100-acre land in 2023 to build our new factory. In the future, we will strive to become the world's leading CMC manufacturing company, and the prospects are limitless.

We have passed ISO9001,ISO14001, ISO22000 and HACCP, BRC,HALAL, Kosher and FSSC 22000 in the past decade. And the final products are widely used in food, pharmaceutical, toothpaste,daily chemicals, battery new energy, textile printing, dyeing, ceramics, papermaking, oil drilling industries and other fields.

    The company has always adhered to the product quality policy of "quality is competitiveness" and strictly implemented the whole-process quality control and product quality traceability system. It has successively passed ISO9001 international quality management system, ISO14001 environmental management system, 22000 food safety management system and HACCP audit certification. As a governing unit of the China Cellulose Industry Association, the company has high visibility and strong influence in the industry. It has successively won honorary titles such as "Provincial Quality and Efficiency Private Enterprise", "Provincial Contract-abiding and Trustworthy Enterprise", and "Shandong Consumer Satisfaction Unit". 

    Our company uses natural plant fiber as the main raw material. The CMC products produced by our company are white powder in appearance, tasteless, odorless and non-toxic. The content of heavy metals such as lead and arsenic and the total number of bacterial colonies all meet the corresponding national production standards for food additives and have the highest purity. It has reached 99.9%. Our company strictly controls product quality, adheres to the consistent principles of "safety, health, and environmental protection" and in accordance with industry standards, monitors product quality in an all-round way, and wholeheartedly provides customers with "high-quality, efficient, and applicable" products. The self-developed "Linguang" brand CMC with high viscosity, high substitution degree and high mesh penetration rate has become a well-known brand in domestic and foreign markets. "Linguang" brand CMC has been rated as "Quality Trustworthy Product" and "Inspection-Free Product" by its partners for ten consecutive years. The sales market covers the country and is exported to Europe, America, Southeast Asia, Africa and other international markets. The company has established partnerships with Mengniu, Wahaha, Shengli Establish long-term strategic cooperative relationships with well-known domestic and foreign companies such as oil fields.

    The company has built a mechanized and highly precise CMC production line to achieve an annual output of 20,000 tons of high-quality CMC at full capacity. In recent years, due to repeated epidemics and heavy environmental pressure, the company has seized the opportunity to make decisive decisions, carry out automated transformation of the workshop, upgrade and build GMP workshops, improve product standardization with mechanized operations, ensure product accuracy with digital operation, and upgrade product cleanliness with automated transmission. , changing the production method that relies solely on manual operation, greatly reducing labor intensity and improving work efficiency, while optimizing and improving the working environment. At the same time, the company continues to increase investment in technological innovation and technology research and development, builds high-standard laboratories and modern application laboratories, introduces leading technical talents in the cellulose industry, actively undertakes national cellulose industry scientific and technological innovation projects, and expands research on product technical parameters. , enrich the company's product specifications and models, and broaden the company's product application access. Deeply explore the company's independent intellectual property rights, vigorously develop key core technologies with independent intellectual property rights, accelerate the transformation and upgrading of the company, and improve the company's own scientific and technological productivity.

    The company has established a research and development center composed of professional and technical personnel with master's and undergraduate degrees to develop forward-looking products and provide customers with a full range of technical services to ensure that customers achieve the best results when using products and ensure that customer satisfaction reaches 100%.

Qingdao Linguang Biochemical Ltd is is one of wholly-owned subsidiary of Dongying linguang, Relying on manufacturing experience, technical service and research capacity of parent company, We can serve customers with best products and solutions. And successively completed the development of high-quality markets in Asia, Europe, Middle East, Australia, Africa,USA and sold more than 70 countries and regions in the world.
