Strategic Positioning and Core Mission

“Reimagining the Energy Future Through Materials Science” As the technology hub driving the company’s sustainable development, the Technology Research and Development Center shoulders three core missions: breaking through critical material technology bottlenecks, building an independent intellectual property system, and promoting deep integration among industry, academia, and research. Grounded in three key areas—artificial graphite, silicon-carbon composite materials, and hard carbon materials—we are committed to becoming a global leader in new-energy materials technology. The Center integrates resources across basic research, applied development, and industrialization, fostering end-to-end innovation capabilities—from laboratory breakthroughs to large-scale production.

Technological Reserves and Cutting-Edge Exploration

Focusing on fundamental research into next-generation energy storage materials, we are strategically positioning ourselves in forward-looking areas such as solid-state battery anodes and hard carbon for sodium-ion batteries. Our annual R&D investment accounts for over 10% of revenue, ensuring a continuous supply of technological reserves for the company.

The Core Driving Force Behind Industrial Upgrading

By developing innovative products such as high-first-efficiency artificial graphite and low-expansion silicon-carbon composites, the company has boosted the energy density of its flagship products by over 15% and reduced costs by 8% over the past three years, thereby strengthening its market position.

Open Innovation Hub

Establish an innovation consortium comprising “universities, research institutes, and industrial chains,” take the lead in building provincial-level key laboratories, and spearhead national science and technology tackling projects to achieve efficient commercialization of technological achievements.

R&D System Architecture

Multi-level innovation network

Basic Research Platform

Advanced Carbon Materials Laboratory:Equipped with cutting-edge instruments such as a high-resolution transmission electron microscope (with a resolution of up to 0.1 nm) and an in-situ XRD analysis system, we can dynamically characterize the microstructure of materials—effectively performing a CT scan on negative electrode materials. We are focusing our research on fundamental studies including the growth mechanisms of graphite crystals and the controlled modulation of pores in hard carbon.

Center for Computational Materials Science:Establish a materials genome database and use machine learning algorithms to predict the thermal expansion coefficient of silicon-carbon composite materials, shortening the new material development cycle by 40%.

Core Laboratory Cluster

Artificial Graphite R&D Platform:Possessing end-to-end development capabilities—from raw material coke microcrystal regulation to graphiteization process optimization (achieving a 30% reduction in energy consumption)—we have developed differentiated products such as high-rate fast-charging batteries (5C) and long-cycle batteries (>3,000 cycles).
Silicon-Carbon Innovation Lab:Breaking through CVD vapor-phase deposition technology, we have developed a multi-level buffer carbon skeleton structure that effectively addresses the challenge of silicon volume expansion (expansion rate < 20%), achieving a cycle life of over 500 cycles.
Hard Carbon Pilot Plant:An original process utilizes resources such as asphalt to prepare hard carbon, achieving a specific capacity of 299.9 mAh/g (at 0.2C for 100 cycles) and boosting the initial Coulombic efficiency to 89%.

Industry-University-Research Collaborative Mechanism

Adopt the “Three-Pronged” Innovation Model:Joint project initiation (with universities proposing fundamental research topics), joint problem-solving (with company engineers stationed on campus for R&D), and joint technology transfer (sharing intellectual property rights). We have collaborated with numerous domestic universities to establish the **“Advanced Anode Materials Joint Laboratory,”** which annually undertakes an average of 5 core technology攻关 projects.
