Lithium Polymer has the following advantages: 1. Good safety performance. Polymer lithium-ion batteries in the structure of the aluminum-plastic soft packaging, high safety.2. Thickness is small, can be made thinner. The thickness can be less than 1mm, which is in line with the direction of the current demand for cell phones.3. Light weight. Polymer batteries are 40% lighter than steel lithium batteries of the same capacity and 20% lighter than aluminum batteries.4. Large capacity. Polymer batteries than the same size specifications of the steel shell battery capacity of 10-15% higher than the aluminum shell battery 5-10% higher, become the first choice for color screen cell phones and MMS cell phones. 5. small internal resistance. The internal resistance of polymer batteries is smaller than that of general liquid batteries, which greatly reduces the self-consumption of batteries and prolongs the standby time of cell phones. 6. Good discharge characteristics. Polymer batteries use colloidal electrolyte, which has smooth discharge characteristics and a higher discharge platform.
