Expanded metal mesh for battery mesh Introduction Current collectors of thin film batteries must be flexible, have high surface area, be cost-effective, and allow fluids to flow through them. Our expanded metal fits all these requirements and it is micro-permeable by design, therefore it allows the transport of the protons from the anode to the cathode through the membrane. It also forces the electrons to travel around a conductive path to the cathode, functioning as a key component in battery manufacturing. The expanded metal is manufactured in slit coils or sheets and is processed as discs or most any shape as required.
