Carbon Aerogels (CAs) for Supercapacitor and Catalyst Support, 5 g/bottle, CSCSCA

In electrochemical systems, carbon aerogels (CAs) are the ultimate "architectural" support. Unlike mesoporous nanospheres, which are individual particles, a carbon aerogel is a monolithic, 3D interconnected network. As a catalyst support for supercapacitors, it provides a continuous "electron highway" and a sponge-like structure that can be loaded with massive amounts of pseudocapacitive materials (like Ni, Co, or Fe oxides) while maintaining ultra-low density.

State-of-the-art carbon aerogels, especially those modified with nitrogen (N-doped) or transition metals, are setting new records in energy storage: (1) Specific Capacitance: Hierarchical aerogels have recently achieved ~172 F/g in pure EDLC mode and up to 508 C/g when functioning as hybrid battery-capacitor electrodes. (2) Cycle Stability: Biomass-derived carbon aerogels (e.g., from cellulose or polybenzoxazine) show exceptional durability, with 102% capacitance retention after 5,000 cycles at 1 A/g, often improving over time as the electrolyte fully "wets" the internal structure. (3) Energy Density: High-performance AC cells using organic electrolytes have pushed energy densities to 67 Wh/kg at power densities of 1237 W/kg.

Notes: Please try to store the carbon aerogels powder in a dry place.
