| 摘 要： | 通过对锂离子电池放电过程的模拟计算,研究了放电电流密度对电池容量,过电势,浓度分布以及电池温度的影响。结果表明:放电电流密度的增大使电池放电容量降低,引起电池内部过电压,浓度,液体电势等分布梯度的增大,因而引起放电热效应的增加,电池温度升高。

| Abstract: | The effects of current density on discharge capacity,over potential,concentration gradation and temperature were studied through electro-chemical simulation of lithium-ion cells discharge performance.The results show that the increasing of discharge current brings about the reducing of discharge capacity,besides the rising of over potential,concentration grads and electrolyte potential grads,which causes the rising of cells temperature. |
