rechargeable batteries 18650 li ion Manufacturers

In recent years, with the explosion of TWS earphones, new rechargeable button batteries with advantages such as high endurance, high security and personalization have been unprecedentedly popular in various small wearable devices such as TWS earphones, smart watches, smart glasses and smart speakers.

Lithium ion batteries have been widely used in notebook computers, video cameras, mobile communications and other portable appliances due to their unique performance advantages. At present, the large capacity lithium ion battery developed has been put into trial use in electric vehicles, and is expected to become one of the main power sources of electric vehicles in the 21st century, and be applied in artificial satellites, aerospace, energy storage and other fields. So, what are the main advantages of lithium batteries for electric vehicles?

Lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of the single battery is 3.2V, and the charging cut-off voltage is 3.6V~3.65V.

There are three main packaging forms of lithium battery, namely, cylinder, square and soft package. Different packaging structures mean different characteristics, each of which has its advantages and disadvantages. Among them, there are many types of cylindrical lithium batteries, such as 14650, 17490, 18650, 21700, 26500, etc.

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
