The development of next-generation lithium-based rechargeable batteries with high energy density, low cost, and improved safety is a great challenge with profound technological significance for portable electronics, electric vehicles, and grid-scale energy storage. Specifically, advanced lithium battery chemistries call for a paradigm shift to electrodes with high Li to host ratio based on a conversion or alloying mechanism, where the increased capacity is often accompanied by drastic volumetric changes, significant bond breaking, limited electronic/ionic conductivity, and unstable electrode/electrolyte interphase.

储能复合纳米材料的设计：过去的成功和未来的机遇

具有高能量密度，低成本和改善的安全性的下一代锂基可再充电电池的开发是巨大的挑战，对于便携式电子设备，电动汽车和电网规模的储能具有深刻的技术意义。具体来说，先进的锂电池化学需要基于转换或合金化机制，将锂电池模式转换为高锂对主体比率的电极，在这种情况下，容量的增加通常伴随着剧烈的体积变化，明显的键断裂，有限的电子/离子电导率和电极/电解质界面不稳定。
