316L Stainless Steel Felt Sheet or Roll for Battery, Electrolyzer, and Fuel Cell, CBEFCSS316LFE

SS316L felt is an advanced 3D porous current collector made by sintering micro-sized metal fibers into a non-woven structure. Unlike flat foils or standard meshes, "felt" provides a randomly interconnected fiber network that mimics a metallic sponge, offering the highest surface area and porosity for high-performance flow battery electrodes, electrolyzer, and fuel cells. Its main features and advantages are detailed below:

(1) Extreme Porosity (Up to 95%): The high void volume allows for massive active material loading without clogging the electrode. It also facilitates rapid electrolyte flow, which is essential for redox flow batteries.

(2) 3D Conductive Network: Every fiber is sintered together, creating a seamless path for electrons. This significantly reduces charge transfer resistance throughout the depth of the electrode.

(3) Mechanical Integrity: The sintering process ensures the fibers won't shift or compress easily. This "self-standing" structure is rugged enough to serve as both the current collector and the structural backbone of the electrode.

(4) Corrosion Resistance: The "L" in 316L stands for low carbon, which prevents intergranular corrosion during the high-temperature sintering process or under the aggressive electrochemical conditions of aqueous cells.
