Investigation on the Electrochemical Performances of Mn2O3 as a Potential Anode for Na-Ion Batteries

Currently, the development of the sodium-ion (Na-ion) batteries as an alternative to lithium-ion batteries has been accelerated to meet the energy demands of large-scale power applications. The difficulty of obtaining suitable electrode materials capable of storing large amount of Na-ion arises from...
