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.

锂离子电池电化学模型的应用

锂离子电池因其高能量密度和长循环寿命而被认为是一种很有前途的能源。在本文中,作者提出了锂离子电池容量衰减和电池中的电化学反应的模型。为了改善电解质和锂/电解质界面的性能,将添加剂三-(2,2,2-三氟乙基)-硼酸盐 (TTFEB) 添加到碳酸盐基电解质中。作者还研究了影响电池容量的因素,包括固体电解质界面 (SEI) 电阻、活性材料颗粒半径、放电速率和环境温度。仿真结果表明,锂离子电池的寿命是由容量衰减率、电化学机理和物理化学参数决定的。
