Phenolic Resin Microspheres for Porous Carbon and Carbon Microsphere Precursors

Core advantages

Complete spherical shape with precise and controllable particle size

Dispersion index SPAN<0.8, free of crushed powder and agglomeration. After carbonization, the carbon microspheres feature uniform morphology and stable mass transfer channels, suitable for CVD silicon-carbon deposition process.

Ultra-high carbon yield, more economical for mass  production

Carbon yield after curing and carbonization ≥52%, with low raw material loss and minimal batch-to-batch fluctuation of carbon yield, greatly reducing the production cost of carbon materials.

Ultra-low ash content, no interference from metal impurities

Ash content<0.1%, no residual strong alkali catalyst, no micropore blockage, and no adverse impact on battery electrochemical performance, adsorption capacity, and catalytic activity.

Strong process compatibility and flexible customization

Compatible with all process routes, including template method, direct carbonization, and activation pore-forming; particle size, hue, and crosslinking degree can be adjusted on demand, with supply ranging from lab-scale samples to ton-level batches.

Precise temperature control and staged polymerization

Adopting precision staged temperature control technology to accurately control the reaction process and directionally guide molecular chain growth, ensuring a controllable reaction.

Extreme stability with minimal error

Batch errors of core indicators such as D50, SPAN, and strength are controlled within an extremely narrow range, meeting the require-ments of high-end   manufacturing.
