Скачать или смотреть Mechanistic Model of Lithiation and Delithiation in Silicon - Yang Jiang

Silicon has been an attractive alternative to graphite as an anode material in lithium-ion batteries. Here we develop a new mechanistic model of silicon anodes considering multi-step phase transformations, crystallization and amorphization. The asymmetric voltage hysteresis of silicon is reproduced, the abrupt appearance of the crystalline Li-Si phase in lithiation and its gradual disappearance in de-lithiation are retrieved. The model is a necessary tool for future design and development of high-energy-density, longer-life silicon-based LIBs.
