制备多孔锂离子电池电极的研究进展

摘要

着重介绍近年来多孔锂离子电池电极材料合成的研究进展。软模板剂法合成温度较低，生成的多孔材料孔型可控性好。纳米铸造、凝胶结晶及生物材料作底物等硬模板剂方法可在温度较高的条件下合成电极材料，该材料多为介孔和大孔材料。电极沉积法、超声波降解法、水热合成法等非模板剂法合成条件较为简单，合成材料孔径分布较广。%　　The research progress in porous electrode materials for lithium-ion batteries was focused on. The reaction temperature of soft-templating was relatively low, and could produce well-controlled porous materials. Hard-templating method contained nanocast-ing method, colloidal crystal templating method and biotemplating method. Porous materials which pore sizes distributed in meso-pore or macropore was synthesized under relatively high temperature by these methods. Non-templating method, included electrode-position method, ultrasonication method and hydrothermal synthesis, could be applied to synthesize porous materials with broad pore size distribution with simple synthesis conditions.
