Wisdom Power 18650 lithium ion battery manufacturer detailed production process

18650 lithium ion battery manufacturer is the current mobile power, laptop batteries and other one of the most commonly used batteries, the common form is the diameter of 18mm, 65mm length of the cylindrical batteries. The most common lithium battery on the market is Cylindrical (Cylindrical) package, which is the most widely used in the field of notebooks and flashlights. The benefits of this package are unified specifications, convenient automation and large scale production. In addition, there are Prismatic (square ) Soft package package, common in mobile phones and tablet PCs, the most direct benefits of such packages are thin and easy to control the thickness of the product.
