A study of Cu-doping effects in Na2Mn3O7 layered cathode material for Sodium-ion battery. National Laboratory Astanahttp://nur.nu.edu.kz/handle/123456789/6622In recent years, sodium-ion batteries (SIBs) attracted great attention owing to their rich Earth-abundant resources, environmental friendliness, low cost, and high energy efficiency. To be compared to lithium-ion batteries the developing advanced cathodes play a key role in enhancing the performance of SIBs. Layered transition metal oxides NaxMO2 (M = Co, Mn, Fe, Ni, etc.) are one of the promising cathodes for SIBs due to the variable composition, abundant active center, and good electrochemical performance.enAttribution-NonCommercial-ShareAlike 3.0 United StatesType of access: Embargosodium-ion batteriesNa2Mn3O7Sodium-ion batteryAbstract
