Applications of Ferrous Oxalate in Lithium Iron Phosphate (LFP) Batteries
1. As a Precursor for Lithium Iron Phosphate Cathode Materials
Ferrous oxalate is an important precursor in the production of lithium iron phosphate cathode materials. By mixing ferrous oxalate with lithium dihydrogen phosphate and then sintering in an inert atmosphere, pure olivine-structured lithium iron phosphate can be obtained with high crystallinity and more efficient lithium-ion diffusion pathways. The advantages of this process include:
Single Sintering Process: Unlike the traditional ferric phosphate method, the ferrous oxalate method does not require a carbothermal reduction reaction and only needs a single sintering process, making the process simpler.
Higher Compaction Density: The ferrous oxalate method can produce lithium iron phosphate materials with higher compaction density, which helps to shorten the lithium-ion migration path, reduce battery impedance, and support faster charging speeds.
 Higher Energy Density: By increasing the compaction density, more active material can be packed into the same volume, thereby significantly improving the unit storage capacity of the battery.
2. Improving Battery Performance
Electrochemical Performance: Ferrous oxalate as a precursor helps in producing lithium iron phosphate cathode materials with excellent electrochemical performance, including higher specific capacity and better cycle stability.
Rate Capability: The lithium iron phosphate materials produced by the ferrous oxalate method have finer and more uniform particles, which improve the lithium-ion diffusion rate and thus support higher rate capabilities.
3. Process Advantages
Cost-Effective: The ferrous oxalate method has relatively low production costs and does not require large-scale modification of existing production lines.
Environmentally Friendly: The ferrous oxalate method produces fewer impurities during the production process and has a smaller environmental impact.
4. Practical Applications
Power Batteries: The lithium iron phosphate materials produced by the ferrous oxalate method are widely used in power batteries for electric vehicles, such as the Shenzhou series batteries by Contemporary Amperex Technology Co. Limited (CATL) and the second-generation Blade batteries by BYD.
Energy Storage Batteries: These materials are also suitable for energy storage batteries, meeting the requirements of large-format cells for energy storage applications.

7,Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8,Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
