Material characteristics:
Graphene oxide is an oxide of graphene whose unique structure gives it outstanding physical and chemical properties. Small-size high-purity graphene oxide has a higher specific surface area and more abundant active sites, which enable it to play an important role in batteries.
The application in batteries:
High energy density: Small size and high purity graphene oxide as an electrode material can provide higher voltage output. Compared with conventional graphite electrodes, its voltage output can reach 0.6 to 1.0 volts, or even higher. This allows batteries with the material to have a higher energy density and be able to store more charge in the same volume, thus extending the battery life of the device.
Fast charge and discharge: Small-size high-purity graphene oxide has a larger electrode surface area and excellent electrical conductivity, which makes the transfer of lithium ions between electrodes faster, resulting in faster charge and discharge speeds. The battery using this material can greatly shorten the charging and discharging time and improve the efficiency of the battery.
Stability and safety: In the charge and discharge process, the electrode material of small size and high purity graphene oxide has high structural stability, which helps to reduce the aging phenomenon of the battery and extend the service life of the battery. In addition, in the case of high temperature or overcharge, its structural stability is also good, and it is not easy to occur thermal runaway or short circuit, thus improving the safety of the battery.
