3.7v 90mah lipo battery Manufacturers

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.

1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

The "2016 Third China Lithium Battery Industry Summit and Data Conference for Top 100 Lithium Battery Enterprises", sponsored by the lithium power big data and co organized by the electric big data and starting point research, with the theme of "discovering trends and grasping the future", was grandly held in Sheraton Grand China Shenzhen Hotel. More than 400 CEOs and leaders from various subdivisions of the national lithium battery industry chain attended to jointly explore the development trend of the lithium battery industry and grasp the new trend of the lithium battery industry in the future. Through industry interaction, we will promote better collaboration between upstream and downstream of the industry chain, and bring greater breakthroughs and breakthroughs to China's lithium battery industry chain. At this summit, Zhou, Head of Research and Development of Haisida Power

There are two basic processes of internal short circuit of battery caused by metal foreign matters, as shown in Figure 1. In the first case, large metal particles directly pierce the diaphragm, causing a short circuit between the positive and negative electrodes, which is a physical short circuit.
