As a state-of-the-art secondary battery, lithium-ion batteries (LIBs) have dominated the consumer electronics market since Sony unveiled the commercial secondary battery with LiCoO₂ as the negative electrode material in the early 1990s. The key to the efficient operation of LIBs lies in the effective contact between the Li-ion-rich electrolyte and the active material particles in the electrode. The particle properties of the electrode materials affect the lithium ion diffusion path, diffusion resistance, contact area with the active material, the electrochemical performance and the energy density of batteries. To achieve satisfied comprehensive performance and of LIBs, it is not only necessary to focus on the modification of materials, but also to balance the properties of electrode material particles. Therefore, in this review, we analyze the influence of particle properties on the battery performance from three perspectives: particle size, particle size distribution, and particle shape. A deep understanding of the effect and mechanism of particles on electrodes and batteries will help develop and manufacture practical LIBs.

作为最先进的二次电池，自从索尼推出带有 LiCoO ₂的商用二次电池以来，锂离子电池 (LIB) 一直主导着消费电子市场1990年代初作为负极材料。LIBs高效运行的关键在于富锂离子电解质与电极中活性材料颗粒之间的有效接触。电极材料的颗粒特性影响锂离子的扩散路径、扩散阻力、与活性材料的接触面积、电化学性能和电池的能量密度。为了获得令人满意的LIBs综合性能，不仅需要关注材料的改性，还需要平衡电极材料颗粒的性能。因此，在这篇综述中，我们从粒径、粒径分布和颗粒形状三个角度分析了颗粒特性对电池性能的影响。
