3D open-worked inverse opal TiO 2 and GeO 2 materials for long life, high capacity Li-ion battery anodes

摘要

AbstractIn this short review, we overview some advancements made in Li-ion battery anode development, where the structural arrangement of the material plays an important role. Specifically, we summarise the benefits of 3D macroporous structure imposed the anode material, in order to improve ionic and electronic conductivity in the absence of conductive additives and binders. Two anode materials are overviewed: TiO2and GeO2. These are either high capacity anode materials or accessible, abundant materials that are capable of very stable and long-term cycling. We have focused this review on 3D inverse opal structures of these anodes and summarise their enhanced behaviour by comparing their performance metrics to a range of nanoscale and porous analogues of these materials.Highlights?A survey and comparison of TiO2and GeO2anodes materials for lithium-ion batteries?Overview of the role of material structure on the performance of TiO2and GeO2battery anodes<
