Graphene carbon nanotubes greatly extend the life of next-generation lithium-ion batteries

On the road to a new lithium-ion battery design, the use of graphene materials is becoming a new choice. For example, SiNodeSystems uses graphene materials to create the anode part of high-capacity, high-performance lithium-ion batteries. Recently, researchers at Rice University in the United States have also used graphene to conduct experiments to achieve similar effects in the form of graphene nanoribbons (GNR). A team of Rice University researchers-including James Tour, a professor of chemistry, engineering and computer science, and post-doctoral researcher JianLin-successfully created a proof-of-concept battery anode through GNR and tin oxide materials, which can supply higher than normal battery anodes capacity. Generally, the anode of a lithium-ion battery or the part of the battery that stores lithium ions is mainly made of tin oxide and graphene.

The researchers said that after 50 charge-discharge cycles, the test anode made by the research team still retains twice the capacity of graphene in the anode of existing lithium-ion batteries. This greatly extends the service life of the battery and pave the way for a variety of commercial applications that use the same type of battery design in various electronic devices and electric vehicles.
