PEG is a polyoxyethylene condensate with excellent wetting properties. Depending on the precursor performance indicators and manufacturing conditions,PEG with different molecular weights (PEG1500, PEG2000, PEG4000, or PEG6000) are available for selection
Forms a highly graphitized, uniform, and thin carbon layer on the surface of LFP/LMFP, enhancing the conductivity and electrode compaction density of the cathode material |
Prevents precursor particle agglomeration during drying process, suppresses excessive grain growth of the cathode material, and controls particle size distribution |
High purity, easily water-soluble, and compatible with both solid-phase and liquid-phase production processes |
Low content of magnetic particles, Cu/Zn particles, and Na/K impurity elements |
