The electrochemical properties and performances of lithium-ion batteries are primarily governed by their constituent electrode materials, whose intrinsic thermodynamic and kinetic properties are understood as the determining factor. As a part of complementing the intrinsic material properties, the strategy of nanosizing has been widely applied to electrodes to improve battery performance. It has been revealed that this not only improves the kinetics of the electrode materials but is also capable of regulating their thermodynamic properties, taking advantage of nanoscale phenomena regarding the changes in redox potential, solid-state solubility of the intercalation compounds, and reaction paths. In addition, the nanosizing of materials has recently enabled the discovery of new energy storage mechanisms, through which unexplored classes of electrodes could be introduced. Herein, we review the nanoscale phenomena discovered or exploited in lithium-ion battery chemistry thus far and discuss their potential implications, providing opportunities to further unveil uncharted electrode materials and chemistries. Finally, we discuss the limitations of the nanoscale phenomena presently employed in battery applications and suggest strategies to overcome these limitations.

锂离子电池中的纳米现象。

锂离子电池的电化学性能和性能主要受其构成的电极材料支配,其固有的热力学和动力学特性被认为是决定性因素。作为补充固有材料特性的一部分,纳米化策略已广泛应用于电极以改善电池性能。已经发现,这不仅利用了氧化还原电势的变化,插层化合物的固态溶解度以及反应路径的纳米级现象,还改善了电极材料的动力学,而且还能够调节其热力学性质。此外,材料的纳米化最近使人们发现了新的能量存储机制,通过它可以引入未探索的电极类别。本文中,我们回顾了迄今为止在锂离子电池化学中发现或利用的纳米级现象,并讨论了它们的潜在影响,为进一步揭示未知的电极材料和化学提供了机会。最后,我们讨论了目前在电池应用中使用的纳米级现象的局限性,并提出了克服这些局限性的策略。
