The Electrochemical Stability of Starch Carbon as an Important Property in the Construction of a Lithium-Ion Cell

Abstract

This paper shows use of starch-based carbon (CSC) and graphene as the anode electrode for lithium-ion cell. To describe electrochemical stability of the half-cell system and kinetic parameters of charging process in different temperatures, electrochemical impedance spectroscopy (EIS) measurement was adopted. It has been shown that smaller resistances are observed for CSC. Additionally, Bode plots show high electrochemical stability at higher temperatures. The activation energy for the SEI (solid–electrolyte interface) layer, charge transfer, and electrolyte were in the ranges of 24.06–25.33, 68.18–118.55, and 13.84–15.22 kJ mol−1, respectively. Moreover, the activation energy of most processes is smaller for CSC, which means that this electrode could serve as an eco-friendly biodegradable lithium-ion cell element.

Starch as the Flame Retardant for Electrolytes in Lithium-Ion Cells

“…In Table 4, the diffusion coefficient and conductivity are shown, while the whole methodology was prepared by us in a previous work [54] and can also be found in the literature [55][56][57][58][59][60][61]. The values are high, which indicates that the diffusion was efficient.…”
