Technology Innovation

Over the Past Five Years, NCM Cathode Materials for Power Batteries Have Undergone Rapid Evolution Trend

Key Directions

Driving Factors & Current Progress

High-Nickel & Cobalt-Reduction Technology Path

Nickel content rapidly increased from NCM 523/622 to NCM 811 and above. "Ultra-high nickel Ni ≥ 90%" and "low-cobalt / cobalt-free" have become clear directions.

Increase Energy Density: Higher nickel content delivers higher capacity. Reduce Cost & Risk: Decreases reliance on expensive cobalt with unstable supply chains.

Performance Enhancement & Structural Innovation

To address the structural stability issues of high-nickel materials, core modification technologies like "single-crystal" structures, "concentration gradient" design, and "surface coating & bulk doping" have been developed.

Solve High-Nickel Bottlenecks: Improve cycle life and safety. For example, gradient structures can suppress microcracks. Technology Integration: NCMA (nickel-cobalt-manganese-aluminum) materials further stabilize structure through aluminum doping.

Market & Application Diversification

Forms a "duopoly" with lithium iron phosphate LFP, but their market shares fluctuate. NCM focuses on high-end passenger vehicles and long-range models.

Cost-Effectiveness: After subsidy phase-outs, LFP made a strong comeback in mid-to-low-end vehicles and energy storage due to cost advantages. Scenario Matching: NCM maintains its position in performance and long-range scenarios due to its high energy density.

Supply Chain & Cost Control

Companies are accelerating "upstream resource integration" and promoting "large-scale production" to reduce costs.

Ensure Supply Security: Secure key mineral resources (e.g., nickel, lithium) through equity investments, joint ventures, etc. Technical Cost Reduction: High-nickel, low-cobalt formulations are themselves a primary cost-reduction path.

Cutting-edge Technology Exploration

"Lithium-rich Manganese-based" cathodes and cathodes compatible with "solid-state batteries" have become R&D hotspots for next-generation tech.

Break Energy Density Ceiling: Lithium-rich manganese-based materials have a much higher theoretical capacity than current NCM. Adapt to System Change: Solid-state batteries require solving interface stability issues between the cathode and solid electrolyte.
