Carbon Black Additives for Electric Double Layer Capacitors (EDLC): Impact on Capacity and Cycle Life - (PPT)

摘要

There is ongoing need to increase capacity, operating voltage and cycle life and reduce cost of EDLC. Cabot has developed high surface area carbon blacks that can serve as both conductive additive and active material for EDLC. We have recently improved purity and form of these new carbon blacks. Results suggest that high purity SC2 carbon blacks can improve cycle life of EDLC's operating at higher voltage.
