This study investigates the effect of carbon coating sequence on the crystal structure and electrochemical performance of Li1+xFe1-XPO4 (Li-rich LFP). Two approaches were compared: carbon coating before (C/BLF) and after (C/ALF) LFP crystal structure formation. The C/ALF process produced a dense carbon layer, reducing overpotential, underscoring the importance of process for improved material performance.
