Spherical Porous Carbon (XFP061, 3000 m2/g, >250 F/g, Aqueous Electrolyte) for Supercapacitor, 50 g/bottle, CSSPCXFP061

Spherical Porous Carbon (SPC) is a high-performance electrode architecture that addresses several mechanical and electrochemical limitations of traditional, irregularly shaped activated carbon. In a supercapacitor, the spherical geometry offers unique advantages in terms of packing density, ion diffusion, and electrode stability.

While standard activated carbon (like YP-50F) consists of jagged, irregular flakes, SPC consists of uniform "microspheres. (1) High Packing Density: Uniform spheres can be packed more tightly than irregular flakes. This increases the volumetric energy density—meaning you can store more energy in the same physical space. (2) Reduced Ion Transport Distance: In a spherical particle, the distance from the surface to the center is consistent in all directions (r). This prevents "dead spots" in the center of the material that ions might not be able to reach during fast charging. (3) Low Equivalent Series Resistance (ESR): The point-to-point contact between smooth spheres creates a continuous conductive network with lower resistance compared to the random "interlocking" of jagged particles. (4) Better Slurry Rheology: Spherical particles flow more easily in a liquid slurry. This makes it easier to coat smooth, uniform electrode films on aluminum current collectors without defects or "pinholes."

Notes: Please try to store the spherical porous carbon powder in a dry place (glovebox is the best option).
