　　The Japan Institute for Material and Materials Research (NIMS) recently announced that a research team of theirs has successfully synthesized manganese oxide nanosheets and graphene alternately overlapping materials, and this new type of negative electrode material can increase the battery capacity by more than twice.

　　It is reported that the composite material, as the negative electrode material of lithium and sodium ion rechargeable batteries, can increase the charge and discharge capacity of the battery by more than twice, and can prolong the repetitive service life, or it will solve the current problem of battery capacity and life.

　　The research team dispersed manganese oxide nanosheets in the solution and mixed them with graphene to synthesize an alternating multilayer laminated composite material. This time, the composite material obtained by combining the two substances at the molecular level has been difficult to achieve with a single material. The high characteristics. It is reported that in addition to being used in rechargeable batteries, this composite material can also greatly improve the performance of energy storage and conversion systems such as supercapacitors and electrode catalysts.

　　Comment: A negative electrode material in which manganese oxide nanosheets and graphene alternately overlap is very complicated just by listening to the name, and complex materials are often difficult to realize industrialization. Although it is still far away from industrialization, such research is an indispensable link in the development of lithium batteries. Taking graphene as a breakthrough point is actually very common in the scientific research community. Although graphene has always had a less reliable impact on people, frankly speaking, I still have hope for graphene.
