The 1.5v rechargeable li ion battery has high energy density, low self-discharge rate, no memory effect and no pollution to the environment, and its performance is superior to other energy storage battery types in all aspects. The 1.5v rechargeable li ion battery is generally composed of five parts: cathode material, anode material, separator, electrolyte, battery case, etc. The 1.5v rechargeable li ion battery is a type of rechargeable battery, which mainly relies on the movement of lithium ions between the cathode and the anode to work. In the process of charging and discharging, the lithium-ion battery intercalates and deintercalates back and forth between the two electrodes. When charging, it deintercalates from the cathode, and then enters the anode when passing through the electrolyte. And the anode is in a lithium-rich state. When discharging, it is the opposite process. On the one hand, the charging principle of the 1.5v rechargeable li ion battery. When the 1.5v rechargeable li ion battery is charged, the lithium atoms of the cathode ionize into positively charged lithium ions and leave. Positively charged lithium ions start from the cathode, pass through the thickness of the film to the anode, and synthesize lithium atoms with electrons in the anode. The carbon as the anode has a layered structure. It has many micropores. When the lithium ions reach the anode, they will be inserted into the micropores of the carbon layer. The more lithium ions are inserted, the higher the charging capacity. On the other hand, the discharge principle of the 1.5v rechargeable li ion battery. In the same way, when the 1.5v rechargeable li ion battery is discharged, the lithium ions embedded in the carbon layer of the anode are released and move back to the cathode. When the more lithium ions return to the cathode, the higher the discharge capacity. What we usually call battery capacity refers to the discharge capacity. 

The contamination of the connector of the fiber jumper is an important cause of network failure. The fiber end face of the connector is contaminated by dust, which will result in poor optical signal transmission quality. Generally, the main location for cleaning the optical fiber is at the connector ports at both ends. There are two main cleaning methods, one is dry cleaning, and the other is wet cleaning. Commonly used dry cleaning tools include cassette-type fiber optic cleaning boxes and one-touch cleaning pens, and wet cleaning tools include dust-free wipes and cleaning sticks. 1. Store the fiber jumper correctly. No matter whether the optical fiber jumper is in use or not, do not bend or stretch it excessively. Some damages caused by bending are clearly visible. However, in some cases, the loss may not be easily judged, such as micro-deformation of optical fiber caused by ultra-low temperature, millimeter-level displacement caused by defects of buffer or jacket, poor installation or Other factors. Because this type of damage cannot be found directly, it is often overlooked and will cause greater problems in the long run. To avoid further losses, we should pay attention to the following points: (1) Do not bend the fiber jumper beyond its minimum bending radius, especially in the narrow space of high-density fiber wiring. (2) Use appropriate tools to redesign the fiber jumper path to protect the cables from damage, such as horizontal cable management racks. (3) Do not bump the optical fiber connector, otherwise the end face may be worn, and the fragments will pierce the skin. Therefore, it is recommended to put a dust cap on the jumper at any time. (4) If you need equipment to detect and identify faults, such as damage and full attenuation inside the fiber jumper, you can use an optical time domain reflectometer (OTDR) and a fiber microscope.

At the same time, compared with the nanocrystalline core wound with tape, the magnetic permeability of the nanocrystalline core is still very low, and the soft magnetic performance is unstable.  Application areas of nano magnetic cores. The noise of nano-magnetic core is mainly the source of circuit interference, in many power electronic devices. Various filter components must be used to reduce noise. Magnetic powder cores play a key role in the filter as the main component of the differential mode inductance. In order to obtain a better filtering effect, the magnetic powder core material is required to have the following performance characteristics: high saturation magnetic induction, wide constant permeability characteristics, good frequency characteristics, good AC and DC superimposition characteristics and low loss characteristics. In response to the above requirements, we have successively developed iron powder cores, notched amorphous alloy iron cores, iron-nickel aluminum powder cores (MPP powder cores) and other soft magnetic materials for inductors. These materials have exerted their respective advantages and advantages under different application conditions. effect. Currently, UP powder cores occupies a major share in the high-end market. However, due to the complex powder core manufacturing process of nanocrystalline cores and the high price of raw materials, the price of powder cores remains high and the scope of application is subject to certain restrictions. In recent years, iron-based nanocrystalline cores have attracted much attention due to their low price, simple preparation process, and excellent performance. Research on them is quite active. It is expected to replace the partial use of UP powder cores and be applied in the high-frequency field.
