Polymer battery.703048 polymer battery

　　The lithium polymer battery is used as positive alloys. It uses polymer conductive materials, poly acetamine, polyiline or polyphenol to make negative electrodes. Organic solvents are used as electrolytes. The ratio of lithium polyiline batteries can reach 350W.H/kg, but it is only 50-60W/kg than the power. The temperature is -40-70 degrees, and the life span is about 330 times.

　　Compared with lithium ion batteries, the characteristics of lithium polymer batteries are as follows:

　　1. Relatively improving the problem of battery leakage, but it has not completely improved.

　　2. Can be made into thin batteries: with a capacity of 3.6V 250mAh, its thickness can be as thin as 0.5mm.

　　3. The battery can be designed as a variety of shapes.

　　4. It can be made into a single high voltage: The battery with a liquid electrolyte can only be connected in series with several batteries, and because the polymer battery has no liquid itself, it can be made into a multi -layer combination in a single piece to achieve high voltage.

　　5, discharge, theoretically 10%of lithium -ion batteries that are higher than the same size.

　　Lithium polymer battery (Li-Polymer, also known as polymer lithium-ion battery), has many advantages such as higher energy, miniaturization, ultra-thin, lightweight, and high safety. Based on this advantage, the lithium polymer battery is a battery that can be made into any shape and capacity, thereby meeting the needs of various products; and it uses aluminum -plastic packaging. , Will not explode, only swelling. In the polymer battery, the electrolyte plays the dual function of the diaphragm and the electrolyte: on the one hand, isolated the positive and negative electrode materials like a diaphragm, so that there is no self -discharge and short circuit inside the battery, and on the other hand Version lithium ions between extremes. The polymer electrolyte has not only good conductivity, but also has the characteristics of light quality, good elasticity, and film -easy film unique to polymer materials. It also conforms to the development trend of light, safe, efficient, and environmental protection in the chemical power supply.
