PREPARATION AND SILVER MODIFICATION OF LIFEPO4/C FOR LI-ION BATTERIES

LiFeP0(4)/C and LiFeP0(4)/C+Ag samples were prepared by sol-gel method. Samples were characterized by XRD, SEM, EIS and electrochemical discharge and charge tests. Silver modification does not affect the olivine structure of LiFeP0(4) but enhances its electrochemical performance in terms of discharg...
