文摘

LiMn0.7Fe0.3PO4–LiFePO4–C was fabricated by ball milling and high-temperature sintering. The synthesized core–shell structure had a concentration gradient of Fe and Mn. Core–shell LiFePO4/LiMnPO4 as positive material showed high discharge capacity. Core–shell structure had high electrical conductivity and Li-ion transport rate.
