16340 battery

　　Japan has developed a new negative electrode material: it can increase the capacity and life of 16340 battery

　　The Japan Institute of Materials Science and Technology (NIMS) recently announced that one of their research teams has successfully synthesized a material in which manganese oxide nanosheets and graphene overlap alternately. This new anode material can increase battery capacity by more than twice.

　　It is reported that this composite material, as the negative electrode material of lithium and sodium-ion rechargeable batteries, can more than double the battery's charge and discharge capacity and extend its repeated service life. It may solve the current problem of incompatible battery capacity and service life.

　　The research team dispersed manganese oxide nanosheets in the solution and mixed them with graphene to synthesize an interactive multi-layer laminated composite material. This time, by combining the two substances at the molecular level, the composite material was obtained that is difficult to achieve with individual materials. of high characteristics. It is reported that in addition to being used in rechargeable batteries, this composite material can also significantly improve the efficiency of energy storage and conversion systems such as supercapacitors and electrode catalysts.

　　Comment: The negative electrode material, which consists of alternating manganese oxide nanosheets and graphene, is very complicated just by the name, and complex materials are often difficult to achieve industrialization. Although it is still far away from industrialization, such research is an indispensable link in the development process of 16340 battery. Using graphene as a breakthrough point is actually very common in the scientific research community. Although graphene has always had an unreliable impact, frankly speaking, the author still has hope for graphene.
