Abstract

In this work, we report the electrochemical properties of 0.5Li₂MnO₃·0.25LiNi_0.5Co_0.2Mn_0.3O₂·0.25LiNi_0.5Mn_1.5O₄ and 0.333Li₂MnO₃·0.333LiNi_0.5Co_0.2Mn_0.3O₂·0.333LiNi_0.5Mn_1.5O₄ layered-layered-spinel (L∗LS) cathode materials prepared by a high-energy ball-milling process. Our L∗LS cathode materials can deliver a large and stable capacity of ∼200 mAhg^-1 at high voltages up to 4.9 V, and do not show the anomalous capacity increase upon cycling observed in previously reported three-component cathode materials synthesized with different routes. Furthermore, we have performed synchrotron-based in situ X-ray diffraction measurements and found that there are no significant structural distortions during charge/discharge runs. Lastly, we carry out (opt-type) van der Waals-corrected density functional theory (DFT) calculations to explain the enhanced cycle characteristics and reduced phase transformations in our ball-milled L∗LS cathode materials. Our simple synthesis method brings a new perspective on the use of the high-power L∗LS cathodes in practical devices.
