Figure 4
(a) Raman spectra of C- LiFePO4 powder at various stages of charge – discharge process (half charge(HC), full charge(FC), half discharge(HC) and full discharge(FD)) in frequency range 150 to 1200 cm−1. (b) Raman spectra of C- LiFePO4 powder in the frequency range 600 to 1800 cm−1 (inset presents resolved Raman spectra of the residual carbon using Gaussian distribution function).
