Specific surface area of battery negative electrode material
Carbon electrodes for capacitive technologies
Furthermore, many authors in the literature assume that the surface area of the electrode/electrolyte interface in Eq. (1) is equivalent to the BET surface area of the electrode material, and thereby overestimate the values of gravimetric capacitance in the narrow pores (see also Section 4.1) [109], [110]. More and more often, the regularized ...
