Title: MnO.sub.2 anode for Li-ion and Na-ion batteries
Authors: Qian, J 
Lau, S 
Issue Date: 14-Apr-2020
Abstract: In the present invention there is provided an MnO.sub.2 electrode with improved electrochemical properties, and a method of preparation of an electrode, wherein there anode comprises a substrate at least partially coated with MnO.sub.2 nanosheets (MnNSs) forming additive free MnO.sub.2 thin films. The method includes providing MnO.sub.2 nanosheets (MnNSs) suspension with diameters less than 50 nm; printing the MnNSs suspension on substrates to form MnO.sub.2 thin films (MnTFs); and annealing the MnTFs at C. for at least 100 minutes. Energy storage device comprising the MnO.sub.2 electrode such as a Na-ion cell, and a Li-ion cell are also described.
