Polyimide diaphragm modification technology
Polyimide diaphragm modification technology Polyimide diaphragm modification technology - Polyimide Coatings - Cheersonic PI nanofiber membrane prepared by electrospinning technology has high porosity and good electrolyte wettability. However, high porosity will also reduce the mechanical properties of the diaphragm, which will put pressure on the assembly and use of the battery. On the other hand, the large pore size of the PI nanofiber membrane also brings about the [...]
