Accurate surface control of core–shell structured LiMn 0.5 Fe 0.5 PO 4 @C for improved battery performance

Core–shell structured LiMn 0.5 Fe 0.5 PO 4 @C was achieved via in situ resorcinol–formaldehyde polymerization followed by graphitization. A 3 nm carbon coating produced the best battery performance. The carbon shell can inhibit the metal dissolution and reduce the heat released during cycling.
