摘要： The present invention provides the compound LiMn2--x-yNaxMyO4/Na1-zMnLizMtO2/Na2CO3, to be used as a positive electrode for rechargeable lithium ion battery, where M is a metal or metalloid, 0.0≤x≤0.5; 0.0≤y≤0.5; 0.1≤z≤0.5; 0.0≤t≤0.3; as well as the method for producing it. The synthesis process includes disolving or mixing the precursor metals and then calcining them in air or controlled atmosphere in a temperature range between 250° C. and 1000° C., and for a time range of 0.5 h to 72 h to obtain the composite proposed with the interaction of its three present phases, presenting a high retention capacity during repeated loading/unloading cycles and excellent discharge capacity both at room temperature and up to 55° C.
