A new generation of lithium polymer batteries in the shape of the theory can be done, shape diversity, improve the flexibility of the battery modeling design, so that you can match the product demand, made into a number of shapes with the capacity of the battery, for the application of equipment developers in the power supply solutions to provide a high degree of design flexibility and adaptability. No pollution to the environment, is a real green battery.
First, what is a soft pack lithium battery
1. a soft pack battery in fact, we should be able to think of many application scenarios, it is not strange in our lives, in addition to power lithium batteries, power batteries are the most common battery components in 3C electronic equipment. For example, the internal cell phone is integrated, can not be disassembled without authorization of the rechargeable battery.
2. soft pack rechargeable batteries, the difference depends critically on the lithium case encapsulation material is not the same, is the choice of aluminum-plastic composite film (commonly known as aluminum-plastic film). Other lithium batteries and positive level, negative level, lithium battery electrolyte, diaphragm and other lithium battery materials are similar.
Second, lithium battery packaging
1. lithium battery case overall packaging, can be divided into: the first generation, steel shell; second generation, aluminum shell; third generation, soft pack aluminum-plastic film.
2. lithium rechargeable batteries rechargeable batteries greater harm, is the lithium battery material is likely to be unstable and other unexpected comprehensive elements, triggering thermal runaway, resulting in invisible rechargeable batteries within the vapor deposition. Steel or aluminum shell, resulting in a fixed space, limiting the expansion of the vapor, so that the rechargeable battery explosion. That way, the emergence of the battery's soft package package, should come into being. Soft pack battery, commonly used aluminum plastic film is too soft, tangible deformation. Once the safety risk, at most, the gas drum cracked.
Third, the advantages of soft pack lithium batteries
In addition to soft pack lithium batteries, relative safety. Compared with the steel shell, lithium batteries can also save net weight, volume, reduce internal resistance. That way, the relative density of lithium batteries to improve the quality or bulk density, it is very beneficial. In addition, the soft pack battery also has a low loss of circulation system, design program packaging appearance of a variety of characteristics.
