建立了循环线性电位扫描作用下单个尖晶石微粒作为微电极嵌入锂离子的数学模型。该模型既考虑了锂在颗粒内的扩散，又考虑了颗粒-电解液界面的动力学。与传统氧化还原体系预测的峰电流密度不同，该模型预测的峰电流密度与扫描速率成线性关系，且与传统氧化还原体系的峰电流密度不同。
A mathematical model is presented for the lithium intercalation of a single spinel particle as a microelectrode under the stimulus of a cyclic linear potential sweep. The model includes both lithium diffusion within the particle and kinetics at the particle-electrolyte interface. The model is used to predict that peak current densities depend linearly on the scan rate to a certain power with a constant term, which is different from the predicted peak current density for a conventional redox system.
