锗基锂离子电池负极材料的制备及研究进展

Process in the Preparation of Ge-based Anode Materials for Lithium-ion Battery

随着便携式电子产品及电动汽车的快速发展,提高锂离子电池能量密度和功率密度的研究日益增多,其中负极材料作为锂离子电池必备部件之一已成为重要的研究方向。商用的石墨负极因理论容量较低限制了其应用,锗具有较高的理论比容量和优异的物理化学性质,成为锂离子电池负极材料的研究热点。本文介绍了不同形貌和组成的锗基纳米负极材料的制备方法以及国内外的研究进展,并对未来的发展方向进行了展望。

Along with the rapid development of portable electronic products and electric vehicles,the research on lithium-ion batteries(LIBs)with high energy density and power density has attracted more and more attention.Anode material as a necessary component of electronic device has become an important research direction.Commercial graphite anode is limited by its low theoretical capacity.Germanium-based nanomaterials have emerged as important candidates for lithium-ion battery anode materials owing to their high theoretical specific capacity and unique chemical and physical properties.This review will focus on preparation methods,current applications and future development of germanium nano materials with different morphologies and composition in LIBs.
