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 Tiger Head 1.5v rechargeable li ion battery basically has no memory effect and can be charged and discharged at any time without affecting the quality of the battery. The 1.5v rechargeable li ion battery has the advantages of high capacity density, high operating voltage, wide operating temperature range, long cycle life, and high safety performance. It is the mainstream development direction of current rechargeable batteries.
In general, people would worry about the risk of overcharge and overdischarge. While with the special smart chip, there is no need to worry about it when charging the Tiger Head 1.5V rechargeable battery. When it is fully charged, the smart chip would recognize it immediately and be automatic power-off. It is best to perform a deep discharge of the 1.5v rechargeable li ion battery after one month of use, that is to say, use up the remaining power of the battery, and then perform a full charge for three consecutive times, so as to maintain the high performance of the battery . The 1.5v rechargeable li ion battery is fully charged at one time, which can reduce the number of recharges and improve the service life of the battery.
Charging method of 1.5v rechargeable li ion battery.
1. It is recommended to charge at night, because the current fluctuation at night is relatively small and suitable for charging.
2.Avoid charging at excessively high temperatures even though the Tiger Head 1.5V Li-on rechargeable battery has the function of temperature recognition, with which it can automatic power-off when the temperature is higher than 40℃.
3.If you want to maximize the effectiveness of the 1.5v rechargeable li ion battery, you need to use it frequently to keep the electrons in the lithium battery in a flowing state.
High temperature tape is mainly used in the electronics industry. The temperature resistance is usually between 120 degrees and 260 degrees. It is often used for painting, baking leather processing, coating masking and fixing in the manufacturing process of electronic parts, printed circuit boards and high-temperature processing masks. High temperature tapes include KAPTON high-temperature tape; Teflon high temperature tape; high-temperature masking tape; PET green high temperature tape; high-temperature double-sided tape, etc.

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..jpg)
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.
