<p>The industrialization of lithium-rich cathode materials requires high capacity and compaction density. Controlling the precursor to a spherical shape is a good way to enhance compaction density, while a suitable primary particle size can maintain capacity. However, the primary particles tend to grow quickly during sintering, negatively impacting the material’s capacity. In this work, an innovative idea of regulating the bending of primary particles was proposed to inhibit particle growth during sintering by increasing their gap. The result shows an average primary particle size ranging about 383.6 nm after sintering, meeting the need for high capacity. The highly spherical morphology of secondary particles ensured the need for high compaction density. Electrochemical performance tests showed a specific capacity of 230.2 mAh.g−¹ at 0.1 C in the voltage range of 2.5–4.55 V. The compaction density was tested to 2.9 g.cm⁻³. This method provides a viable technical route for the industrialization of Li-rich cathodes.</p>
