Scientists Use Conductive Nanodiamonds To Improve The Energy Storage Capacity Of Water-Based Batteries

wallpapers Industry 2020-08-11

It is reported that scientists have discovered that the use of conductive nanodiamonds as electrode materials in water-based batteries can significantly improve the energy storage capacity of the batteries. As a new type of energy-saving and environmentally-friendly energy storage element, supercapacitors have attracted widespread attention.

Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy. A supercapacitor nanodiamond has a positive electrode and a negative electrode. There is a separator between the two electrodes. The electrolyte is filled between the positive and negative electrodes. The porous electrode has a larger surface area to absorb the electrolyte's charge so that the capacity can be Reached high. Since no chemical reaction occurs during the energy storage process, this capacitor can be charged and discharged hundreds of times.

Supercapacitors have low cost, low-temperature resistance, high power density, fast charging speed, long service life, and environmental friendliness. Therefore, supercapacitors can be used in a range of fields, such as automobiles, wearable devices, medical treatment, backup power supplies, mechanical devices, smart meters, etc.

Scientists use a technology called "Microwave Plasma Assisted Chemical Vapor Deposition (MPCVD)" to manufacture these electrodes and test their performance by testing their characteristics. They found that in a basic two-electrode system with an aqueous sulfuric acid electrolyte, the voltage generated by these electrodes is much higher than that of traditional batteries, making the energy and power density of the supercapacitor much higher. Furthermore, they found that even after 10,000 charge-discharge cycles, the electrode remained remarkably stable. Nano-diamond doped with boron has proven its value. The boron-doped nanodiamond electrode is suitable for water-based supercapacitors, and it is ideal for high-energy storage devices with high-speed charge and discharge.
