Abstract
In the present invention there is provided an MnOelectrode with improved electrochemical properties, and a method of preparation of an electrode, wherein there anode comprises a substrate at least partially coated with MnOnanosheets (MnNSs) forming additive free MnOthin films. The method includes providing MnOnanosheets (MnNSs) suspension with diameters less than 50 nm; printing the MnNSs suspension on substrates to form MnOthin films (MnTFs); and annealing the MnTFs at 260-320° C. for at least 100 minutes. Energy storage device comprising the MnOelectrode such as a Na-ion cell, and a Li-ion cell are also described.
