mp3 battery 3.7v 120mah Manufacturers

There are no absolutely safe batteries in the world, only risks that are not fully identified and prevented. Make full use of the people-oriented product safety development concept. Although the preventive measures are insufficient, the safety risks can be controlled.

The electrolyte is a conductive ionic conductor between the positive pole and the positive pole of the battery. It is composed of electrolyte lithium salt, high-purity organic solvent, necessary additives and other raw materials in a certain proportion. It plays an important role in the energy density, power density, extensive temperature applications, cycle life and safety performance of batteries.

What is the development prospect of lithium battery pack industry in the next few years? Where is the development direction? Lithium battery affects the industrial reform of new energy fields such as energy storage, and relates to the development of China's new energy vehicle market. With the in-depth development of national environmental protection, the development scale of China's lithium battery industry will become larger and larger in the next few years. So, what is the future development prospect? Where is the development direction? Let's listen to what these industry leaders say. 1、 Changes in the application field of lithium batteries Since 2015, the industrial structure of lithium battery packs in China has changed significantly, and the demand for power lithium batteries has grown rapidly. In 2016, the power lithium battery market accounted for

Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.
