From May 13 to May 15, 2026, the 18th China International Battery Fair (CIBF 2026) was successfully held at the Shenzhen World Exhibition & Convention Center. As a globally influential event in the new energy battery industry, CIBF 2026 gathered thousands of enterprises, technical experts and business partners from the entire lithium-ion battery industrial chain. Hunan Sentai Biotechnology Co., Ltd. (Sentai Bio-Tech), a leading cellulose ether manufacturer, made a remarkable appearance at Booth 4B013, focusing on its high-performance battery-grade CMC (sodium carboxymethyl cellulose) and a full range of core products, attracting extensive attention from global visitors.
At CIBF 2026, Sentai Bio-Tech centered its exhibition aroundbattery-grade CMC, the core functional material for lithium-ion batteries, and displayed a comprehensive product portfolio to meet diverse industry needs. The key exhibits included:
Battery-grade CMC: Tailored for power batteries, energy storage batteries and consumer electronics batteries, featuring ultra-high purity, low metal ion content, strong adhesion and excellent electrolyte compatibility.
Instant CMC: Independently developed by Sentai, with the advantages of high viscosity, fast dissolution speed and convenient use, solving the pain points of traditional CMC products.
PAC (Polyanionic Cellulose) and CMS (Sodium Carboxymethyl Starch): High-performance products widely used in oilfield drilling, papermaking, ceramics and other fields.
Among all exhibits, battery-grade CMC was the focus of attention, as it plays an irreplaceable role in optimizing lithium-ion battery performance and promoting the development of the new energy industry.
With the global energy transformation accelerating and the electric vehicle (EV) and energy storage markets expanding rapidly, the demand for high-performance battery materials is growing exponentially. As a key non-active material in lithium-ion batteries, CMC (sodium carboxymethyl cellulose) serves as a critical binder, directly affecting the battery’s energy density, cycle life and safety.
Sentai’s battery-grade CMC is engineered with high-purity raw materials and precise production processes, ensuring strict control over substitution degree, molecular weight distribution and impurity content. In practical applications, it undertakes three core functions:
Dispersion & Thickening: Improves the uniformity of electrode slurry, preventing agglomeration of active materials and conductive agents, and ensuring stable slurry rheology.
Adhesion Enhancement: Strengthens the binding force between active materials and current collectors, reducing pole piece powder falling and cracking, and extending battery cycle life.
Electrochemical Stability: Has excellent compatibility with electrolytes, no side reactions, helps reduce internal resistance, and improves battery rate capability and low-temperature performance.
Compared with traditional binders, Sentai’s battery-grade CMC is green, non-toxic and environmentally friendly, complying with global low-carbon trends and meeting the strict standards of international high-end battery manufacturers.
The outstanding performance of Sentai’s CMC products at CIBF 2026 stems from the company’s more than 20 years of technical accumulation and standardized operation. Established in 2003, Hunan Sentai Biotechnology Co., Ltd. is a technology-driven enterprise dedicated to the R&D, production and sales of cellulose ether products, including CMC, PAC andCMS.
Located in Tianyi Industrial Park, Xiangtan, Hunan, the company covers an area of 15,000 square meters, employs over 100 professionals, and has a registered capital of 13.9 million RMB. With an annual production capacity of 10,000 tons of CMC and 5,000 tons of CMS, Sentai is equipped with fully automatic production equipment, advanced testing facilities and a strict quality management system.
Sentai’s core competitive advantages lie in:
Technological Innovation: Cooperates with well-known universities and research institutions, inherits international advanced CMC production technology, and independently develops high-performance products such as instant CMC.
Quality Assurance: Passed ISO 9001:2015, ISO 14001:2015 and IATF 16949:2016 certifications, ensuring products meet global high-end industry standards.
Comprehensive Service: Provides one-stop solutions including product customization, technical support, after-sales service and efficient logistics. With a 3,000-square-meter warehouse, Sentai ensures stable supply and fast delivery.
Global Market Layout: Products are sold well in China and exported to Asia, Europe, the United States, Africa and other regions, establishing long-term cooperative relations with well-known enterprises worldwide.
During CIBF 2026, Sentai’s professional team communicated in-depth with every visitor, introducing CMC product performance, application cases and technical advantages in detail. Many visitors showed strong interest in Sentai’s battery-grade CMC and instant CMC, and some reached preliminary cooperation intentions on the spot. The exhibition not only enhanced Sentai’s brand awareness in the new energy field but also helped the company grasp the latest market demand and technical trends.
Although CIBF 2026 has concluded successfully, Hunan Sentai’s commitment to providing high-quality cellulose ether products and professional services remains unchanged. We sincerely thank all industry friends who visited our booth 4B013 during the exhibition.
