a b s t r a c t The interpretation of the performance of electrochemical capacitors based exclusively on the textural features and surface chemistry of carbons can be insufficient, or even misleading, in the case of materials prepared at low temperatures (typically below 800 °C). It is suggested that the gradual improvement of the electrochemical performances of carbon-based capacitors at hig…
a b s t r a c t In this study, contributions of hemicellulose, cellulose and lignin to the mass and the porous roperties of chars and activated carbons from various lignocellulosic materials were studied. A predictive alculation was established using the experimental results obtained for the three components separately to evaluate the carbonization and activation yields and their respective co…
