Full-lifecycle battery support covering structural safety and thermal management.

Instead of showcasing a single star product, Chambroad   presented a systematic material solution centered on improving battery safety, service life and consistency with a clear overall logic: building a full-lifecycle material support system following the path of "Structural Safety → Electrochemical System → Thermal Management".

▍ HNBR (Hydrogenated Nitrile Butadiene Rubber)

On the afternoon of May 13, Li Yunxue, Application Engineer of Chambroad Sinopoly , delivered a keynote speech titled Application Prospect of Hydrogenated Nitrile Butadiene Rubber in New Energy Batteries. Based on industrial development background and market demands, the speech systematically introduced the company’s project progress and breakthroughs in core bottleneck technologies, with focused elaboration on the performance advantages of HNBR as cathode dispersants and binders. It fully demonstrated Chambroad  ’s strategic layout and innovative strength to empower the new energy industry with new material technologies and address industry pain points.

HNBR was the flagship product highlighted at the exhibition, perfectly aligning with the industry trends showcased at CIBF: accelerated industrialization of solid-state batteries, booming energy storage scenarios, high-voltage fast charging, high energy density and high voltage platforms. Chambroad  ’s HNBR dispersant grades deliver highly efficient dispersion of conductive agents such as carbon nanotubes (CNTs), markedly enhancing slurry stability and uniformity and boosting charge transfer kinetics, with outstanding performance in high-rate charge-discharge and cycle life tests. Meanwhile, featuring both polar structure and elastic properties, HNBR improves the uniform dispersion of active materials and strengthens electrode adhesion when used as dispersants or binders. It has the potential to partially replace PVDF systems, enabling dual optimization of performance and cost.

▍ Aramid Nanofiber Coating Materials

"Safety" emerged as another major trend at the show, and Chambroad ’s nano-material technology provides a robust solution to lift lithium battery separator safety. Chambroad   Jufang New Materials holds the world’s exclusive patented water-based nano-aramid technology, which enables the production of water-based coating slurries and greatly lowers the production threshold and costs of coated separators. Aramid coating not only improves separator heat resistance and mechanical strength but also effectively inhibits lithium dendrite growth, extending battery cycle life and enhancing fast-charging safety. Chambroad  Jufang New Materials is committed to supplying separator manufacturers with competitive nano-aramid raw materials.

▍ Butyl Rubber

Butyl rubber serves as the second safety line for batteries developed by Chambroad Sinopoly . Renowned for ultra-high air tightness, excellent chemical resistance and aging resistance, it delivers reliable material support for sealing, insulation and safety protection of battery systems, acting as a vital guarantee for long-term safe operation of power batteries.

▍ Special Coke for Anodes

Moyuan Carbon Materials ensures stable and controllable supply of anode coke raw materials supported by self-owned processing facilities, guaranteeing consistent quality and on-time delivery. Backed by profound R&D capabilities, it supports flexible customized production to meet diverse application scenarios.

▍ Thermal Conductive Silicone

High temperature resistance and thermal conductivity form the third safety barrier for batteries. Chambroad   thermal conductive silicone integrates comprehensive merits including high thermal conductivity, low impedance, insulation and voltage resistance, shock absorption, corrosion resistance, low volatilization and low VOC. It operates stably over a wide temperature range of -50°C to 200°C, fully meeting the stringent operating conditions of power and energy storage batteries.

The above product portfolio is underpinned by Chambroad  ’s years of deep-rooted R&D system. Adhering to demand-oriented innovation, Chambroad  takes industrial pain points as the starting point of research. Since the 14th Five-Year Plan period, Chambroad  ’s cumulative R&D investment has reached 6.3 billion yuan, and revenue from new products has exceeded 80 billion yuan. It has built a three-dimensional R&D framework consisting of the Central Research Institute plus 18 specialized research institutes, forming full-chain innovation capabilities covering basic research, application development and industrial transformation.

Looking ahead, Chambroad   avoids passive "me-too" R&D and maintains forward-looking layout of emerging energy storage technologies such as solid-state batteries, hydrogen energy and flow batteries. During the 15th Five-Year Plan period, it will collaborate with universities and upstream & downstream industrial partners to incubate more new material solutions based on real industry demands.
