Description
Summary:Lithium-ion batteries are considered as a promising energy source due to the high energy density and long cycle life. In this paper, the authors propose a model of a lithium-ion battery capacity fade and the electrochemical reactions in the battery. To improve the properties of the electrolyte and the lithium/electrolyte interface, the additive tris-(2,2,2-trifluoroethyl)-borate (TTFEB) is added into the carbonatebased electrolyte. The authors also study the factors influencing the battery capacity, including the resistance of solid electrolyte interface (SEI), the active material particle radius, the discharging rate, and the ambient temperature. The simulation results show that the lithium-ion battery life is determined by the capacity decay rate, the electrochemical mechanism, and the physicochemical parameters.
