AI Technical Summary
Existing technologies for increasing the compaction density of lithium iron phosphate suffer from low production efficiency, high energy consumption, large equipment investment, significant environmental pollution, and high post-processing costs, making them unsuitable for large-scale production.
By using fertilizer acid as the phosphorus source and controlling the dropping ratio of the oxidant, the stirring regime, and the temperature rise regime of the aging process, large single crystal iron phosphate is prepared, avoiding the use of additives and template agents, simplifying the process, and reducing production costs and environmental pollution.
The preparation of high-quality large single-crystal iron phosphate has been achieved, which improves electrochemical performance, reduces production costs, simplifies the process, and increases production efficiency, making it suitable for large-scale production.
