Guxin Huang et al.

Summary: In this study, the pre-lithiation performance of Li2C2O4 as a cathode additive was greatly improved by optimizing the combination of conductive additives and catalysts, reducing the particle size, and designing a bilayer electrode. By lowering the delithiation potential, the capacity of Li2C2O4 was increased to its theoretical value and effectively applied to a hard carbon anode.

High-Capacity O2-Type Layered Oxide Cathode Materials for Lithium-Ion Batteries: Ion-Exchange Synthesis and Electrochemistry

Zhaoshun Wang et al.

Summary: The O2-type layered oxide cathode materials have gained significant research attention due to their high specific capacity and unique lattice structure. In this study, we investigated the structural, chemical, and morphological changes during ion-exchange processes for the preparation of these materials using LiBr/hexanol solution and LiNO3/LiCl molten salts. The solution method was found to be preferable for preparing high-capacity O2-type cathode materials, despite slower structural reorganization compared to the molten-salt method. It was discovered that the as-made O2-type cathode materials were actually Li-deficient at their pristine states but could accept more Li ions during the first charge/discharge cycle.

Summary: LRMO, as a cathode material for the next generation commercial LIBs, has high capacity, low cost, and environmentally friendly characteristics. The anionic redox reaction is the origin of its high capacity, but it causes voltage hysteresis and capacity decay. The application of LRMO is limited by the degradation caused by irreversible O loss and phase transition, and modification of unstable oxygen is needed to improve its performance.

Insights into the chemical and structural evolution of Li-rich layered oxide cathode materials

Zhi-Liang Wu et al.

Summary: Through the investigation with in situ Raman spectroscopy, XANES spectroscopy, and HRTEM, it was found that the voltage-fading mechanism of Li-rich materials is nearly reversible in the whole charge-discharge cycle but becomes irreversible upon long-term cycling, leading to structural collapse and undesirable voltage fading. This finding is significant for a better understanding of the redox reaction mechanisms of high-capacity Li-rich cathodes.
