It is reported that the supercapacitor is limited by the conductivity of the electrode material, so that the reversible electrochemical redox reaction only occurs on the surface of the electrode material, which greatly reduces the utilization of the electrode material.
The researchers succeeded in designing and preparing high-electron and ion-conducting hollow-spheroidal basic nickel-nickel-carbonate electrode materials by self-growth and sacrificial template method, and the abundant metal bonds between the crystal structures provided sufficient electron transport channels. The intercalation of hydroxide and water between their one-dimensional chain crystal structural units provides a guarantee for the rapid transport of ions.
Tests have shown that the basic nickel-carbonate electrode material designed by the researchers exhibits excellent rate performance, specific capacity and long stability. In the case of a 100-fold increase in current density, the capacitor capacity retention rate is as high as 96.2%; at a current density of 20 amps per gram, the specific capacity is as high as 108.3 Farah per gram; at 20 amps per gram, 100,000 cycles, capacity retention Up to 85.8%. Therefore, the supercapacitor electrode material has a good industrial application prospect.
A through-bore slip ring is an electrical device that allows current to pass between two points in a rotating assembly without a physical connection. There is no break in the circuit. This is accomplished by passing the current through a rotating brush that contacts a stationary metal ring. The metal ring is mounted on the shaft of the assembly and provides a continuous path for the current.
It is an integrated circuit component that consists of two conducting rings that are separated by a gap or spacer. When the rings are brought into contact, current can flow between them and produce a rotational motion. Slip rings are used in various applications where high efficiency and low power consumption are essential, such as communication systems, motor control systems, and energy harvesting devices.
The through-bore design allows for rotation of the assembly while transmitting power or data. They are often used in applications where there is a need to rotate an object while keeping a power or data connection open, such as on a wind turbine or radar antenna.
The Oubaibo's through-bore slip ring is a newly designed product that has many advantages over other products on the market. It is small and lightweight, making it easy to install and use. The through-bore design also allows for a high degree of flexibility, making it ideal for use in difficult or tight spaces. Additionally, the Oubaibo through-bore slip ring is very efficient, providing a high degree of power transfer with minimal loss.
