Excellent safety factor. Medical instruments with aluminum-plastic soft packaging, its construction is not the same as the plastic shell of liquid batteries, once the safety risk, liquid rechargeable batteries are very easy to explode, and the most rechargeable batteries for medical instruments.
Thin thickness is not big, able to do thinner. Liquid lithium batteries have technical shortcomings if the thinness is millimeters, while medical equipment lithium batteries do not have this problem, and the thinness can be less than a millimeter.
Lighter weight and the same volume specifications of the same type of lithium steel shell compared to the weight of medical equipment rechargeable batteries 40% lighter than the steel shell battery 20% lighter. The appearance can be customized. According to the user's needs to expand or reduce the thickness of the rechargeable battery, deformation of flexible, convenient.
