Analyze the pros and cons of polymer lithium batteries

4. Long service life, the cycle life of normal use can reach more than 500 times. 5. No memory effect, do not use up the remaining power before charging, easy to use. 6. Good safety performance Polymer lithium battery adopts aluminum-plastic soft packaging in structure, which is different from liquid battery with metal shell. Once there is a safety hazard, liquid battery is easy to explode, while polymer battery will only swell. 7. Small thickness, can be made thinner. Such a thin battery can be assembled into a credit card. Ordinary liquid lithium batteries adopt the method of customizing the shell first, and then plugging the positive and negative electrode materials. There is a technical bottleneck to achieve 3.6mm thickness, but polymer batteries do not have this problem. The thickness can reach 1mm or less, which is in line with the current demand for mobile phones. 8. Lightweight polymer electrolyte batteries do not require metal casing as a protective layer. Polymer batteries are 40% lighter than steel lithium batteries of the same capacity and 20% lighter than aluminum batteries. 9. Large-capacity polymer batteries are 10-15% higher than steel batteries of the same size and specifications, and 5-10% higher than aluminum batteries. It has become the first choice for color screen mobile phones and MMS mobile phones. Currently, most new color screen and MMS mobile phones on the market also use polymer batteries. Low internal resistance The internal resistance of polymer batteries is lower than that of general liquid batteries. At present, the internal resistance of domestic polymer batteries can even be lower than 35m, which greatly reduces the self-consumption of the battery, extends the standby time of the mobile phone, and reaches the level of international standards. This polymer lithium battery supports a large discharge current and is an ideal choice for remote control models. It is the most promising alternative to nickel-metal hydride batteries. 11. Customizable shapes The manufacturer does not limit their standard shapes, and can make them economically applicable sizes. Polymer batteries can add or reduce the thickness of the battery according to the needs of customers, develop new battery models, are inexpensive, and have a short mold cycle. Some can even be customized according to the shape of the mobile phone to make full use of the battery shell space and increase the battery capacity. 12. Good discharge characteristics Polymer batteries use gel electrolyte, which has stable discharge characteristics and a higher discharge platform than liquid electrolytes. 13. The shortcomings of a simple protective plate design of polymer lithium batteries: 1. The battery cost is high, and the electrolyte system is difficult to purify. 2. To protect and control the circuit, overcharge or overdischarge will destroy the reversibility of the chemical substances in the battery, which will seriously affect the service life of the battery.
