An Activated Carbon Coated on Titanium (Ti) Mesh Electrode Sheet is a high-performance composite electrode configuration engineered for electrical double-layer capacitors (EDLCs), supercapacitors, and advanced energy storage devices. It pairs the high electrostatic charge storage capability of porous carbon with the superior chemical stability, mechanical strength, and open architecture of a titanium metal mesh current collector.
The main structural features of the activated carbon on Ti mesh are: (1) Active Layer (Activated Carbon Composite): Composed of high-purity activated carbon (featuring specific surface areas ranging from 900 to 2000 m2/g and a hierarchical micro/mesoporous structure), blended with conductive additives (like carbon black or CNTs) and an electrochemical binder (such as PVDF or PTFE/CMC).This layer provides the massive electrochemically active surface area required for non-faradaic electrostatic adsorption and desorption of electrolyte ions. (2) Substrate (Titanium Mesh): Replaces traditional flat metallic foils (such as aluminum or copper) with a woven or expanded titanium wire grid. Corrosion Resistance: Titanium forms a robust passivating oxide film that resists electrochemical oxidation and dissolution across aggressive aqueous, acidic, alkaline, and ionic liquid electrolyte environments. 3D Open Architecture: The open pore structure of the mesh allows electrolyte ions to access the active carbon layer from both sides simultaneously, drastically reducing mass-transfer resistance.
