Brief analysis of the eight advantages of polymer lithium batteries

1. Good safety performance. The structure of the polymer lithium battery is aluminum-plastic soft packaging, which is different from the liquid battery with a metal shell. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only be inflated. 2. Lightweight polymer battery is 40% lighter than steel shell lithium battery of the same capacity, and 20% lighter than aluminum shell battery. 3. The thickness is small, and it can be made thinner. Ordinary liquid lithium batteries adopt the method of customizing the shell first, and then plug in the positive and negative materials. The thickness below 3.6mm has a technical bottleneck, but polymer batteries do not have this problem. The thickness can be less than 1mm, which meets the needs of current mobile phones. 4. Self-defining shape polymer battery can add or reduce battery thickness according to customer needs, develop new battery models, cheap, short mold cycle, and some can even be customized according to the shape of the mobile phone, make full use of the battery shell space, and improve the battery capacity. 5. The high-capacity polymer battery is 10~15% higher than the steel shell battery of the same size and 5~10% higher than the aluminum shell battery. It is the battery of choice for color screen mobile phones and MMS mobile phones. Most of the new color screen and MMS mobile phones on the market now also use polymer batteries. 6. The design of the protective plate is simple. Due to the use of polymer materials, the battery will not catch fire or explode. The battery itself has sufficient safety. Therefore, the PTC and fuse can be omitted when designing the protection circuit of the polymer battery to save the battery. cost. 7. Good discharge characteristics Polymer batteries use gel electrolyte, which has stable discharge characteristics and a higher discharge platform than liquid electrolytes. 8. Small internal resistance The internal resistance of polymer batteries is smaller than that of liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces battery power consumption and extends the standby time of mobile phones, which can reach international standards. The polymer lithium battery supports large discharge currents and is ideal for remote control models, and is the most promising alternative to nickel metal hydride batteries.
