The application of ultra-pure single-layer graphene oxide in batteries is mainly reflected in the following aspects:

Efficient charge and discharge: Because graphene oxide has a high specific surface area and rich functional groups on the surface, it can provide a larger electrode surface area when used as an electrode material, so that lithium ions can be transferred between electrodes more quickly. At the same time, its excellent electrical conductivity also improves the transmission speed of electrons in the battery. These characteristics make the battery have higher charging and discharging efficiency and capacity.

Improve battery performance: In lithium-ion batteries, ultra-pure single-layer graphene oxide can be used as a negative electrode material, and its efficient ion transport performance and stable cycling performance can extend the service life of the battery. In supercapacitors, it can also be used as a positive electrode material to improve the energy density and power density of capacitors.

Electrolyte additives: Graphene oxide nanocomposites can also be used as electrolyte additives to further improve the performance of batteries. For example, in lithium-ion batteries, it can improve battery capacity, cycle performance and safety performance.

In addition, the properties of ultra-pure single-layer graphene oxide, such as easy grafting modification and easy stripping into stable graphene oxide dispersion, also provide more possibilities for the design and manufacture of batteries. For example, it can be in-situ composite with the composite material to give the composite material electrical conductivity, thermal conductivity, enhancement, flame retardant, antibacterial and antibacterial properties, thereby improving the overall performance of the battery.
