Custom Micro Hole Expanded Metal for

Anode and Cathode Electrode Materials Battery Grid 

Expanded metal foils are formed from solid metal foil in a proven, economical “slit-and-stretch” process. They are electrically continuous and, unlike knit or woven meshes, exhibit consistent and predictable conductivity.

It works as current collector and also provides the electrical connection point for the external circuit. It is mainly used in batteries, like Ni-MH battery, Ni-Cd battery and lithium ion cells, etc.

Thin, strong, flexible and lightweight, expanded metal foils will not fray or unravel, and conform readily to complex surfaces, making them well-suited to composite manufacturing processes.
