Product introduction

Figure | a brand square batteries

Square cells have smaller volumes and higher energy density compared to conventional cylindrical cells, and are therefore more common in some specific applications. Square cells usually use lithium-ion battery technology, and its structure is composed of positive electrode, negative electrode, electrolyte and diaphragm. Square cells are widely used in various electronic devices, such as smartphones, tablets, power tools, drones, electric vehicles and so on. It should be noted that the square cell needs to follow the safety operation procedures during the use process, to avoid excessive charge and discharge, too high temperature and physical damage.

6. EPP introduction

EPP is a kind of expanded polypropylene material, it is made of polypropylene resin through a special foaming process, with light weight, high strength, excellent thermal insulation performance and energy absorption performance. EPP has a very light weight and high strength, and its lightweight characteristics make it widely used in automotive, aerospace, sporting goods and other fields. EPP material can effectively absorb the shock energy when stressed, with good buffer and seismic performance. Therefore, EPP is often used as a packaging material, protective material and collision-proof material, which can protect products and equipment from damage.
