Elucidating the Humidity-Induced Degradation of Ni-Rich Layered Cathodes for Li-Ion Batteries

Leiting Zhang et al.

Summary: Ni-rich layered oxides are promising candidates for next-generation Li-ion batteries, but their high surface reactivity leads to side reactions and gas release. This study investigates the moisture sensitivity of LiNi0.85Co0.1Mn0.05O2 through aging experiments and provides insight into the gas release mechanism.

Phase Behavior during Electrochemical Cycling of Ni-Rich Cathode Materials for Li-Ion Batteries

Chao Xu et al.

Summary: The essay explores the rapid performance degradation of layered lithium nickel-rich oxides under specific stress conditions, comparing their structural properties with NMCs and NCAs. It highlights the necessity of reexamining the various high-voltage structural changes in LiNiO2 to aid understanding of accelerated degradation in Ni-rich cathodes.

An in-depth understanding of the effect of aluminum doping in high-nickel cathodes for lithium-ion batteries

Kai Zhou et al.

Summary: Increasing the Al content in NCA from 0 to 5.6% gradually improves cycling, air stability, lattice structure, and interphase stability, but going beyond 5.6% leads to adverse effects. A 5.6% Al doping is suggested to be optimal, suppressing adverse effects and enhancing electrode/electrolyte interphases for improved performance.

Optimizing Cycling Conditions for Anode-Free Lithium Metal Cells

A. J. Louli et al.

Summary: This study focuses on the performance of anode-free lithium metal cells under different cycling conditions, and finds that cycling with an asymmetric slower charge protocol is optimal. The research also examines the effect of depth of discharge and demonstrates the benefit of forming a lithium reservoir in situ. Additionally, a specialized intermittent high depth of discharge cycling protocol is developed for anode-free lithium metal cells.

Unraveling the Intricacies of Residual Lithium in High-Ni Cathodes for Lithium-Ion Batteries

Youngjin Kim et al.

Summary: High-nickel layered oxide cathodes face problems with residual lithium causing slurry gelation and gas evolution. A study showed that Li2CO3 impurity in lithium raw materials increases residual lithium in high-Ni cathodes, while LiOH formed during analyte preparation exacerbates LiOH content in residual lithium. A dry cobalt hydroxide coating on high-Ni cathodes effectively reduces residual lithium content and forms a Co-rich layer that suppresses Li leaching in contact with water.

In situ inorganic conductive network formation in high-voltage single-crystal Ni-rich cathodes

Xinming Fan et al.

Summary: Single-crystal Ni-rich cathodes face issues such as performance degradation and structural instability during cycling. Despite the benefits of using single-crystal Ni-rich cathodes, ion diffusion limitations in large single-crystal particles impact rate capability. The application of an in situ Li1.4Y0.4Ti1.6(PO4)(3) conductive network helps improve lithium-ion transport and cycling life in high-nickel content cathodes.

Capacity Fading Mechanisms in Ni-Rich Single-Crystal NCM Cathodes

Hoon-Hee Ryu et al.

Summary: The study found that despite the high resistance to microcracking, the electrochemical performance of single-crystal NCM cathodes is inferior to polycrystalline NCM cathodes in terms of capacity and cycling stability. During cycling, the lithium concentrations in single-crystal NCM cathodes become spatially inhomogeneous, leading to the coexistence of phases with different unit cell dimensions within a single particle, which affects lithium ion diffusion and causes rapid capacity fading.
