Electrolyte Engineering: Optimizing High‐Rate Double‐Layer Capacitances of Micropore‐ and Mesopore‐Rich Activated Carbon

Various types of electrolyte cation as well as binary cations are used to optimize the capacitive performance of activated carbon (AC) with different pore structures. The high-rate capability of micropore-rich AC, governed by the mobility of desolvated cations, can outperform that of mesopore-rich AC, which essentially depends on the electrolyte conductivity.
