Activated carbons for electrodes of non-aqueous electric double layer capacitors were prepared from composites of poly(methymethacrylate) particles and phenolic resins. Their surface areas can be increased up to 3000 m² g⁻¹ through simple CO₂ activation. Through the characterization of pore properties of the resulting carbons, it was found that the activation process appears to be composed of two steps. The pore properties of the activated carbons were optimized to maximize their performances as electrodes for non-aqueous electric double layer capacitor electrodes.

用于非水双电层电容器电极的高表面积活性炭的经济高效合成

非水双电层电容器的电极用活性炭是由聚甲基丙烯酸甲酯颗粒和酚醛树脂的复合材料制成的。通过简单的CO ₂活化，它们的表面积可以增加到3000 m ²  g ^-1。通过表征所得碳的孔隙性质，发现活化过程似乎由两个步骤组成。优化了活性炭的孔性能，以最大化其作为非水双电层电容器电极用电极的性能。
