摘要: Abstract Coating the members of olivine family LiMPO 4 with conductive carbon is difficult, excepted in case M Fe. To overcome this difficulty, we found possible to coat LiMnPO a thin layer LiFePO take benefit catalytic reaction Fe C, so that 3 nm-thick can be deposited at surface composite. We find electrochemical properties carbon-coated –LiMnPO composite are improved respect LiMn 2/3 1/3 PO solid solution comparable Fe/Mn ratio. Therefore, use as buffer between high-density cathode element (like ) and opens new route improve performance active for Li-ion batteries.
