Microwave-assisted synthesis of CuSe nano-particles as a high -performance cathode for rechargeable magnesium batteries

Electrochemical Mg2+ Displacement Driven Reversible Copper Extrusion/Intrusion Reactions for High‐Rate Rechargeable Magnesium Batteries

“…At present, there are very few cathode materials based on ionic displacement mechanisms that can be used in RMBs (as summarized in Table S2, Supporting Information), and the Cu 2– x Se nanoplates cathode exhibits very competitive electrochemical performances among them, including the cycle stability and rate capability. The magnesium storage performance of cubic‐phase Cu 2– x Se nanoplates is also superior to previously reported hexagonal‐phase CuSe cathode based on traditional conversion reaction mechanism, [ 33 ] owing to the ion displacement mechanism occurs in the cubic‐phase Se 2− based sub‐lattices of Cu 2– x Se nanoplates without causing lattice reconstruction and collapse.…”

“…[22] In addition, the presence of another cathodic peak at 1.11 V is due to the formation of Cu and Li 2 Se. [23] After the second cycle, the two cathodic peaks shifted to 1.97 V and 1.84 V, and their intensities significantly decreased. At the third and fourth cycles, there is no formation of Cu 2 Se, and the reduction peak is located at 1.98 V because of the formation of Cu and Li 2 Se.…”

Ni0.85Se hexagonal nanosheets as an advanced conversion cathode for Mg secondary batteries

“…Furthermore, selection of the cation is also of great significance. Soft acid cations (Cu + and Ag + ) [15][16][17][18][19] would interact strongly with the soft anions and assist the dissociation of discharge product. In this respect, it is thought that quasi-soft acids, Ni 2 + as an example, could also be selected for Mg-storage cathodes.…”
