Lithium ion battery soft packing material in the night view lighting and its various parts

Traffic lights in li-ion battery solar street lamps and lithium electricity solar street lamp installation process, open the packaging of lithium-ion batteries we will find that the lithium batteries are outside a layer of flexible packaging, the packaging is how to form, their function of each part?

in lithium ion solar street lamps and traffic lights with lithium ion solar energy street lamp installation process, opened the lithium ion battery packaging, outside the lithium ion battery core found a layer of flexible packaging. This package is formed, what is the function of each part? About the packing structure of lithium-ion batteries, we first look at the following diagram: can be seen from the diagram, the lithium ion battery of the flexible packaging material ( The aluminum foil packing) In structure is mainly divided into three parts: nylon, aluminum, and polypropylene. The important role of packaging materials is to prevent the battery corrosion or short circuit with the outside world. Specifically, the function of each part is: nylon layer: can effectively prevent air, especially the penetration of oxygen, to maintain the battery internal environment, at the same time ensure that packaging aluminum foil has a good ability of deformation. Note: nylon electrolyte corrosion resistance. Aluminum layer of the function: can effectively prevent moisture penetration into the empty gas, maintain the battery internal environment, and has a certain thickness and strength, prevent damage of external battery. Function: polypropylene layer will not be dissolved organic solvent or swelling of the battery core. It is the most direct for battery core internal environment of encapsulation, protection and insulation, effectively prevent the internal contact with the aluminum layer such as electrolyte, prevent the corroded aluminum layer.
