Principle and application method of polymer lithium battery

　　Lithium polymer battery is a kind of battery that uses polymer as electrode and electrolyte material, and there are many different types of polymer batteries according to the different materials used in the positive and negative electrodes of the battery.

　　Lithium polymer batteries have higher energy density, can be small and thin, lightweight, high safety and low cost, lithium polymer batteries in their construction at least one or more use of polymer materials as the main battery system.

　　In terms of shape, the lithium polymer battery has many advantages such as thin shape, arbitrary area and arbitrary shape: first, the negative electrode material carbon, not only from a wide range of sources, but also can make the battery get high-speed discharge effect; The second is because lithium ions are embedded in carbon, so as to solve the problem that lithium-ion batteries are not safe; Third, the comprehensive performance is good, fast charging speed.

　　Lithium-ion polymer battery shape has high plasticity, and ultra-light, ultra-thin, high capacity, no leakage and high safety, while no lead, no mercury, no cadmium and other toxic elements, is a truly environmentally friendly battery, will not bring any pollution to the environment.

　　Polymer batteries use colloidal electrolytes, which have smooth discharge characteristics and higher discharge platforms. And has a high power capacity, even if the high power charge discharge, high frequency use, can quickly complete the charging process, completely no memory effect, the battery charge and discharge efficiency are 99.8% charge retention ability, monthly charge retention rate is greater than 95%. With the best internal consistency, to ensure the consistency of each "charge and discharge" process, to ensure the longest overall battery life.

　　The polymer lithium battery uses aluminum-plastic flexible packaging in the structure, and once a safety hazard occurs, the polymer battery will only bulge. In terms of safety performance, the following conditions should be met:

　　(1) Short circuit: no fire, no explosion

　　(2) Overcharge: no fire, no explosion

　　(3) Hot box test: no fire, no explosion (150℃ for 10min)

　　(4) Needle: no explosion (with 3mm nails to penetrate the battery)

　　(5) Flat impact: no fire, no explosion (10kg weight from 1M height to the battery)

　　(6) Incineration: no explosion (gas flame barbecue battery)
