摘要
采用J.Newman和R.E.White两种模型对锂离子电池的充放电行为进行了模拟计算,并深入研究了放电电流密度、锂离子固相扩散和固体颗粒平均半径对不同模型模拟结果的影响。结果表明:放电电流密度、锂离子固相扩散和固体颗粒平均半径的改变对J.Newman模型计算结果的影响更明显。
The charge-discharge performance of lithium-ion cells and the effects of current density,lithium ion diffusion in solids,and average radius on discharge capacity and temperature were studied through lithium-ion cells electro-chemical models of J.Newman and R.E.White.The results show that J.Newman's lithium-ion cells model is more sensitive to current density,lithium ion diffusion in solids,and average radius than that of R.E.White's model.
