Synthesis of Cu_3.8Ni/CoO and Cu_3.8Ni/MnO nanoparticles for advanced lithium-ion battery anode materials

We synthesized Cu_3.8Ni/CoO and Cu_3.8Ni/MnO nanoparticles via an easy and scalable solution synthesis. The synthesized Cu_3.8Ni/CoO and Cu_3.8Ni/MnO nanoparticles were annealed to remove the organic surfactants without phase transitions or side reactions. Electrons can be transferred via metallic Cu_3.8Ni, which will not react with lithium ions. The heterogeneous structures of Cu_3.8Ni/CoO and Cu_3.8Ni/MnO nanoparticles could enhance the lithium ion mobility and improve the life cycle, and these materials are therefore promising candidates as high- power-density and high-energy-density anode materials for lithium-ion batteries in diverse applications, such as electrical vehicles.
