　　Application of 18650 power battery to assemble electric vehicle battery

　　All materials for a set of 18650 lithium battery for electric vehicles, including stainless steel battery box, accessory materials, wire tape heat shrinkable film, and a voltmeter. , a protective board, the lithium battery must have a protective board, otherwise it will be scrapped once it is discharged

　　The most critical thing is the 18650 battery. Electric vehicles must choose power cells.

　　The 18650 battery cell is one of the most commonly used batteries for mobile power supplies and notebook batteries. The common shape is a cylindrical battery cell with a diameter of 18mm and a length of 65mm. The most common lithium battery on the market is Cylindrical (cylindrical) packaging, which is the most widely used in the fields of notebooks and strong light flashlights. The advantage of this packaging is that it has uniform specifications and is convenient for automation and large-scale production.

　　In addition, there is Prismatic (square) soft package package, which is commonly used in mobile phones and tablet computers. The most direct benefit of this type of package is that it is light and thin, and it is easy to control the thickness of the product.

　　The safety valve is the standard configuration of each 18650 battery, and it is also the most important explosion-proof barrier, none of them.

　　The working principle of the safety valve: When the internal temperature of the battery is abnormal and the air pressure rises to 1.0-1.2Mpa, the safety valve opens to remove the internal gas to avoid explosion caused by excessive pressure.

　　For Prismatic cells packaged in square soft packages, when the internal air pressure rises, the most common phenomenon is "pregnancy" swelling.
