1. Interface treatment method

　　           　　　CP formulation solution applied to the separator interface using a
　　　　　　　 TREKCOATER interface coating machine
　　           　　　By applying it to the surface, it is possible to form two types
　　　　　　　  of conductive coating layers.

　　           　(1) Formation of a 3D structural coating layer: 2~5 μm thickness (both sides)

　　           　(1) After the electrolyte is filled, it will be in close contact with the LIB
　　　　　　　electrodes and the electrode plates and prevents misalignment of
　　　　　　　separators and ensures dimensional stability, contributing to safety.
　　            　　　Prevents misalignment of separators and ensures dimensional
　　 　　　　　   stability, contributing to safety.

　　           　(2)Effects depending on the treatment method

　　　           　�@ By means of a surface finish featuring a
　　　　　　　　three-dimensional network structure
　　　　　         　Improved stability of Li+ ion transport
