A lithium-ion battery is a type of rechargeable battery that moves lithium ions from the negative electrode of the battery to the positive electrode during discharge, and then moves the lithium ions of the positive electrode back to the negative electrode
when charging.
Recently, researchers at Lawrence Livermore National Laboratory in the United States found that as long as hydrogen is added to the electrodes of lithium-ion batteries, the battery capacity can be greatly increased, allowing it to extend the operating time and accelerate the transmission operation
.
Through experiments and calculations, researchers at Livermore National Laboratory found that in lithium-ion batteries, hydrogen-treated graphene nanofoam electrodes showed higher capacity and faster transmission capacity
.
These findings provide qualitative analysis insights that help design high-power electrodes
based on graphene materials.
The commercial use of graphene materials in energy storage elements, including lithium-ion batteries and supercapacitors, seriously affects its ability to
produce such materials in large quantities at a lower cost.
The commonly used chemical synthesis method will leave a large number of hydrogen atoms at the end, and its effect on the electrochemical performance of graphene is difficult to determine
.
The improved performance of the electrode is an important breakthrough that opens up more real-world applications
.
To study the role of hydrogen versus hydrogenation defects in the lithium-ion storage properties of graphene, the researchers applied different heat treatment conditions that combined with hydrogen exposure, focusing on the electrochemical properties of its 3D graphene nanofoam (GNF), which is mainly composed
of defect-rich graphene.
The researchers used 3D graphene nanofoam because it has a variety of potential applications, including hydrogen storage, catalysis, filtration, insulation, energy absorption, capacitor desalination, supercapacitors, and lithium-ion batteries
.
According to the results, this controlled hydrogen treatment process can also be used in other graphene-based anode materials to achieve optimized lithium ion transport and recyclable storage applications
