Experts Discuss: Technological Advancements and Opportunities in LFP Materials [New Energy Summit]

7.4 High Energy Density LFMP

In 2024, the LFMP market was largely dominated by three companies: Hengchuang Nano, Ronbay Skolande, and Dynanonic, with other companies having minimal shipments, mostly focused on sample delivery.

Although the market size of LFMP remains relatively small, industry investment in it continues to be fervent.

7.5 Large-Scale and Intelligent LFP Production Lines

As LFP capacity continues to grow, there are increasing demands for production equipment to be larger, more intelligent, and more efficient.

(1) Large Vertical Sand Mill

In terms of manufacturing difficulty, vertical sand mills are easier to produce due to the avoidance of sealing issues, resulting in lower costs. Therefore, vertical sand mills are more suitable for products with lower requirements but high production needs.

The vertical structure design of the grinding rotor in vertical sand mills also avoids the spindle deformation issues common in traditional horizontal sand mills. Additionally, the increased pressure from the accumulation of grinding media offers potential for improved grinding efficiency.

(2) Large Rotary Kiln

A rotary kiln produced by a certain company features a furnace tube approximately 40 meters long and about 2 meters in diameter, with a single unit capable of producing over 10,000 mt of LFP annually. The equipment is specifically designed for continuous high-temperature processing of LFP, utilizing an electrically heated external rotary furnace structure. It achieves uniform heating, thorough reactions, consistent product quality, stable and reliable operation, simple maintenance, and low operating costs.

8. Conclusion

1. Cathode materials are the core and key materials of lithium-ion batteries, determining their performance and cost.

2. Due to its cost and safety advantages, LFP has become the market mainstream, with a market share exceeding 70%.

3. With advancements in lithium battery manufacturing and automotive technologies, the application of LFP blade batteries, CTP, CTC, CTB, and the introduction of high-compaction density LFP have significantly increased the energy density of LFP, leading to its large-scale adoption in the EV and ESS markets.

4. The production technology routes for LFP and iron phosphate coexist in a diversified manner. Future development of LFP requires technological improvements in raw materials, production processes, and key production equipment to significantly reduce costs and enhance product performance.

5. High-compaction density LFP, high C-rate LFP, and low-cost LFP represent future development opportunities.
