Enhanced anode performance of manganese oxides with petal-like microsphere structures by optimizing the sintering conditions

摘要

Herein, the rational design and synthesis of manganese oxides (MnO2 and MnO) have been achieved and both of them show petal-like microsphere structures. As anodes for LIBs, MnO exhibits a higher capacity of 751.4 mA h g(-1) after 400 cycles (492.7 mA h g(-1) for MnO2 after 300 cycles) at 2000 mA g(-1).
