Xiangwei lithium batteries are very good and durable.
Advantages of Xiangwei lithium batteries:
High energy density: Compared with other battery technologies (such as nickel-cadmium batteries), lithium batteries have a greater energy density and have the possibility of adding new capacity, for example by adding more nickel to the cathode.
Reduced packaging and weight: Lithium batteries are ideal for portable consumer products. Designers can choose to use prismatic packages, typically smaller than 19mm, or lithium-polymer packages, typically smaller than 5mm. Besides the size advantage, there is also a weight saving due to the chemistry (e.g. solid electrolyte/gel instead of liquid electrolyte) and the packaging used (e.g. film).
