Application Status and Prospect Analysis of Graphite Electrodes in Anode Materials for Lithium-Ion Batteries
1. Application Status: Graphite Dominates the Market but Faces Technological Iteration Pressures
1.1 Dominant Market Position
Graphite anode materials (including natural and synthetic graphite) remain the absolute mainstream in lithium-ion battery anodes, accounting for over 99% of global shipments in 2024. Synthetic graphite, with advantages such as high tap density, excellent cycle performance (>1,500 cycles), and 93% initial efficiency, dominates the power battery sector with over 80% market share. As the world’s largest producer, China achieved a负极材料 (anode material) output of 2.16 million metric tons in 2024, capturing 98.5% of the global market, with graphite anodes comprising over 75% of this total.
1.2 Significant Cost Advantages
Graphite anodes have achieved low costs through economies of scale, with domestic synthetic graphite prices in China dropping from RMB 55,000/ton in 2022 to RMB 16,500/ton in 2024, a 21.43% decline. This cost-effectiveness ensures widespread adoption in price-sensitive sectors like consumer electronics and energy storage.
1.3 Emerging Technological Bottlenecks
Graphite’s theoretical specific capacity is limited to 372 mAh/g, nearing its performance ceiling and struggling to meet the demand for “ultra-long range” in new energy vehicles (NEVs). The pursuit of higher energy density in premium power batteries is driving a shift toward next-generation materials such as silicon-based and hard carbon anodes.
2. Application Prospects: Irreplaceable in the Short Term but Facing Long-Term Substitution Risks
2.1 Short Term (3–5 Years): Graphite Remains Core
- Sustained Demand Growth: Expansion in NEVs and energy storage markets will drive anode material demand, with China’s shipments projected to reach 2.41 million metric tons by 2025, with graphite anodes still accounting for over 70%.
- Technological Optimization Maintains Competitiveness: Liquid-phase coating technologies have extended graphite anode cycle life beyond 2,000 cycles, while 3D porous structural designs enable 15-minute fast charging to 80% capacity, meeting requirements for consumer electronics and low-end power batteries.
- Cost Advantages Remain Unchallenged: Innovations in graphitization processes (e.g., continuous graphitization) further reduce costs, whereas silicon-based anodes remain 3–5 times more expensive, limiting short-term mass adoption.
2.2 Long Term (5–10 Years): Silicon-Based Anodes Gain Traction, Squeezing Graphite’s Market Share
- Silicon-Based Anode Breakthroughs: Advances in nanostructured designs, carbon coating optimizations, and pre-lithiation technologies have improved first-cycle efficiency to over 85%, extended cycle life beyond 1,000 cycles, and reduced costs by 60% from 2022 levels to RMB 180/kg. The global silicon-based anode market is expected to reach RMB 30 billion by 2025, with penetration surpassing 10%, and potentially 25% by 2030.
- Policy and Market Drivers: Global NEV sales are projected to hit 60 million units by 2030, while energy storage capacity is set to grow from 300 GWh in 2025 to 800 GWh in 2030. High energy density demands will accelerate the adoption of silicon-based anodes.
- Graphite’s Niche Retreat: Graphite anodes may retreat to low-end power batteries, energy storage, and consumer electronics, with market share eroded by silicon-based, lithium-metal, and other advanced materials.
2.3 Potential Substitution Risks: Sodium-Ion and Solid-State Batteries
- Sodium-Ion Battery Commercialization: If costs fall below RMB 0.3/Wh, sodium-ion batteries could disrupt graphite anode demand, particularly in energy storage.
- Solid-State Battery Disruption: The combination of solid-state electrolytes and lithium-metal anodes could revolutionize the anode landscape, though commercialization remains 5–10 years away.
3. Industry Trends and Strategic Recommendations
3.1 Technological Iteration Directions
- Graphite Anodes: Focus on enhancing fast-charging performance (e.g., liquid-phase coatings), cost reduction (e.g., continuous graphitization), and longevity (e.g., 3D porous structures).
- Silicon-Based Anodes: Monitor CVD silicon-carbon process maturity, pre-lithiation industrialization, and graphite-silicon composite applications (e.g., BTR’s S+i graphite solutions).
- Emerging Anodes: Lithium-metal and porous carbon anodes for lithium-sulfur batteries are entering pilot stages, with industry-academia collaboration projects tripling since 2022.
3.2 Corporate Strategic Recommendations
- Short-Term Strategy: Develop anodes for high-nickel cathode systems and silicon-carbon composites to enhance product premiums.
- Long-Term Strategy: Invest in core patents (e.g., coating modifications, pre-lithiation) and secure partnerships with global top-5 battery manufacturers to solidify market positions.
- Risk Mitigation: Diversify investments across graphite, silicon-based, and lithium-metal technologies to hedge against substitution risks; prioritize suppliers with strong ESG performance and green manufacturing practices.
4. Conclusion
Graphite electrodes remain indispensable in lithium-ion battery anodes in the short term, underpinned by their low cost, stability, and ongoing technical refinements. However, advancements in silicon-based anodes and rising energy density demands in NEVs pose long-term substitution risks. Companies must balance innovation, cost control, and supply chain resilience to transition from “scale expansion” to “quality enhancement,” ultimately driving the industry toward higher energy density, longer lifespan, and lower costs.
