以还原氧化石墨烯（rGO）为载体，通过简单的合成方法制备了不同质量比的纳米氧化锰（Mn 3 O 4），作为高性能锂离子电池（LIB）的复合负极材料。的Mn 3 O 4/rGO杂化材料已被其特征在于通过一个库的技术，以更好地理解的结构和组成的混合物上的LIB的电化学性能的影响。结果表明，Mn 3 O 4纳米粒子均匀分散在rGO纳米片上。由于有效的电子传导途径和高表面积的性能促进rGO，Mn 3 O 4/rGO杂化材料用作阳极材料表现出增强的可逆容量，循环稳定性，和倍率性能。
Nanosized manganese oxide (Mn3O4) particles grown on reduced graphene oxide (rGO) have been prepared via a facile synthetic method with different weight ratios, as hybrid anode materials for high performance lithium ion batteries (LIBs). The Mn3O4/rGO hybrid materials have been characterized by a library of techniques to better understand the effect of the structure and composition of the hybrids on the electrochemical performance of LIBs. The results show that the Mn3O4 nanoparticles are homogenously dispersed on rGO nanosheets. By virtue of efficient electron conduction pathways and high surface area properties promoted by rGOs, the Mn3O4/rGO hybrid material used as an anode material exhibits an enhanced reversible capacity, cycling stability, and rate capability.
