Abstract
A method for activating carbon via alkali activation processes includes the introduction of water vapor during the activation phase to control the formation of highly reactive by-products. The method includes heating the mixture of a carbon-containing first material and a alkali-containing second material, introducing water vapor at a first threshold temperature and stopping water vapor introduction at a second threshold temperature. The activated carbon material is suitable for carbon-based electrodes and for use in high energy density devices.
