The Role of Ni and Co in Suppressing O-Loss in Li-Rich Layered Cathodes

Edouard Boivin et al.

Summary: It is shown that almost complete eradication of oxygen loss with Ni substitution is due to the presence of a less lithium-rich, more nickel-rich rocksalt shell at the surface of the particles compared with the bulk. Thinner rocksalt shell forms in the case of Ni and Co co-substitution, leading to more abundant oxygen loss. Co doping does not result in a surface shell yet it still suppresses oxygen loss, indicating that two mechanisms exist for oxygen loss suppression.

Boosting energy efficiency of Li-rich layered oxide cathodes by tuning oxygen redox kinetics and reversibility

Chong Yin et al.

Summary: This study focuses on the rational design of an energy-efficient Li-rich layered cathode with high energy, power density and cycling stability by tuning oxygen redox activity. The target material Li1.12Ni0.22Co0.13Mn0.52O2 shows ultra-high energy efficiency (90.6%) at 1C, high capacity (>200 mAh g(-1)) with 98.9% retention, and less than 150 mV of decay after 200 cycles. The compositional change greatly improves the oxygen redox kinetics and reversibility, leading to enhanced energy efficiency and narrowing the gap between scientific interest and practical application in oxygen-redox chemistry.
