Influence of Cobalt and Sodium Doping on MnO/CNT Composite Anode Materials for Li-Ion Batteries

摘要

Li ion batteries (LIBs) have been the leading technology in the portable electronics market since their discovery by Sony in the 1990s. Commercially, their setup is constituted by a graphite anode, a lithium metal oxide cathode and LiPF6 dissolved in a mixture of carbonates as electrolyte, characterized by a maximum energy specific density 150 Wh/Kg [1]. However, the needs of newer and cleaner forms of energy is pushing lithium ion batteries towards higher scale applications, such as the electric grid or automotive, requiring the energy and power density to be at least doubled in the near future.
