Abstract
We report here several synthesis routes and their respective drawbacks/advantages for the preparation of pure LiFePO4. We demonstrate the possibility of using LiFePO4 for electrochemical applications, with respect that an effective carbon coating was realized onto the smallest particles. Actually, to bypass the weak ionic conductivity of lithium iron phosphate, the thinnest would be the particles; the highest would be the performance under severe electrochemical conditions.
