The development of science and technology has made relevant peripheral products also receive corresponding attention. For example, reduce environmental pollution caused by automobile exhaust. Car developers have developed to use lithium batteries as a new energy source instead of petrochemical products to provide energy for cars in order to achieve the goal of zero emissions. Lithium-ion batteries have been widely used in consumer electronic products such as mobile phones, notebook computers, and tablet computers. The reason is that it has the advantages of high energy density, long cycle life, and no memory effect. Lithium battery applications have been extended to vehicles. As the application market becomes larger, the performance requirements of lithium-ion batteries for electric vehicles will affect the technological development trend of lithium batteries and the electrode materials of lithium-ion batteries. Therefore, lithium-ion batteries need to be continuously improved to achieve a replaceable effect. Therefore, the parts that need continuous improvement include volume energy density, weight energy density, cost, and charging current. Since it is widely used, the most important thing is the safety of the battery. Therefore, the research on lithium batteries is very enthusiastic. Mainly divided into the following categories: positive electrode material, negative electrode material, electrolyte, and separator. In my research, I focused on electrode materials, namely anode materials and cathode materials. In terms of materials, the main object is two-dimensional nanomaterials. In terms of new energy, in addition to the above-mentioned lithium-ion batteries as substitutes for petrochemical energy, other alternative energy sources such as hydrogen energy are also attracting more attention in the energy field. Hydrogen can be generated by catalytic reaction to generate energy. There is no pollution in the production process. Therefore, in this thesis, electrocatalysis is also proposed as a method of hydrogen production, so catalytic materials are also one of the areas to be explored.
