锂离子电池预锂化技术的研究现状

Research status quo of prelithiation technology for Li-ion battery

综述近年来锂离子电池预锂化技术,展望预锂化技术的发展方向。负极补锂的方法有锂箔补锂、锂粉补锂、硅化锂粉和电解锂盐水溶液等;正极补锂添加剂有富锂化合物、基于转化反应的纳米复合材料和二元锂化合物等。

The research progress of prelithiation technology in recent years was reviewed, and the future development direction was prospected. The common methods of anode prelithiation were composed of prelithiated by lithium metal foil,lithium metal powder, lithium silieide or lithium saline solution. Cathode prelithiation additives were made up of lithium rich compounds, nanocomposites based on conversion reactions and binary lithium compound and so on.
