“…Among the various anode materials such as carbonaceous material, intermetallic compounds, transition metal oxides and phosphides (M-O and M-P, where M = Fe, Co, Ni, Cu, etc. ), transition metal phosphides attract much attention due to their low polarization and good cycling stability [9][10][11][12][13][14]. However, most metal phosphides have to be obtained at high temperatures or under complex conditions such as hydrothermal synthesis for a long time [15][16][17][18][19][20].…”
