Lithium cuprate (Li2CuO2) was obtained by a solid state reaction and a subsequent ball milling process. Then, the samples were characterized (structurally and microstructurally) and evaluated as CO2 captors.
Manganese partial substitution reveals a drastic improvement in the electrochemical stability of Li2CuO2 during the charge/discharge processes, this is attributed to the increase in the superexchange interaction between copper sites and manganese.
