Use of metal foil in supercapacitor and battery
At present, energy storage devices are mainly supercapacitors and batteries. Among them, supercapacitor is an electrochemical energy storage device between traditional capacitor and rechargeable battery. Supercapacitor has the advantages of high power density, fast charge and discharge, good cycle stability and green environment protection, and is suitable for backup power supply, high frequency charge and discharge, high power output and other scenarios. Batteries provide stable voltage and high energy density.
The electrochemical performance of energy storage devices mainly depends on the electrode active material. Among them, transition metal oxides and sulfides are widely used as electrode materials for energy storage devices due to their unique layered structure, which provides high theoretical specific capacity. However, transition metal oxides and sulfides have low conductivity and poor structural stability, which can easily cause self-aggregation and crushing in the process of ion embedding or dissociation, thus affecting the electrochemical performance of electrode materials.
Foil is used in supercapacitors. Metal foil can be Mo(molybdenum) foil, Fe(iron) foil, W(tungsten) foil, Ti(titanium) foil, Ni(nickel) foil, Zn(zinc) foil, etc. When molybdenum foil is used as the working electrode, it is placed in the electrolyte solution, and the preset voltage is applied for electrochemical corrosion oxidation, and the molybdenum strip coated with molybdenum oxide micro-nano materials can be obtained. The molybdenum strip coated with metal oxide micro-nano material was placed in sulfur containing solution for hydrothermal reaction to obtain the molybdenum strip coated with metal oxide and metal sulfide composite material.
