China Positions to Ban Battery Cathodes & Lithium Processing Tech

Highlights

• China's Ministry of Commerce announced export restrictions on critical lithium processing and battery cathode material technologies.
• Proposed restrictions target key technologies in lithium extraction, purification, and advanced cathode material preparation.
• Potential implementation could reinforce China's dominance in global battery supply chains and disrupt international EV industry efforts.

As Rare Earth Exchanges has already reported, China proposed significant export restrictions on advanced technologies for battery cathode materials and lithium processing. This could very well reshape global supply chains in energy storage and electric vehicle production.

The proposed changes, announced by China’s Ministry of Commerce on January 2, 2025, include restrictions on critical technologies, such as the preparation of lithium iron phosphate (LFP) and lithium manganese iron phosphate (LMFP) cathode materials. These materials are pivotal for high-performance batteries used in electric vehicles (EVs) and renewable energy storage systems.

The restricted technologies encompass key steps in lithium processing, including advanced extraction methods, purification processes, and automated production systems. Specific processes include spodumene-based lithium extraction, direct lithium extraction from brines, and preparation of metallic lithium and lithium alloys. Additionally, the restrictions target technologies related to phosphate-based cathode precursors, which are critical for creating high-density, high-capacity battery materials.

If implemented, these restrictions could limit access to the expertise and technology necessary for non-Chinese entities to develop competitive battery materials, potentially reinforcing China's dominance in the global battery supply chain. This move could disrupt the EV industry and complicate efforts by other countries to secure independent supply chains for energy transition technologies. Feedback on the proposed restrictions is due by February 1, 2025, leaving a narrow window for stakeholders to respond to the potential implications.
