A kinetic study on cobalt-free high-nickel layered oxide cathode materials for practical lithium-ion batteries

Youngjin Kim et al.

Summary: The battery industry is actively reducing the use of cobalt in lithium-ion batteries due to its high price. Cobalt-free, high-nickel layered oxide cathodes have been extensively studied, but their low initial Coulombic efficiency and high residual lithium content hinder their commercialization. This study investigates the factors affecting the Coulombic efficiency of cobalt-free LiNiO2, including particle size, temperature, and current density. The hindrance of the H1-H1' phase transition is more significant with larger particle size, as shown by electrochemical analysis.

A microcrack propagation-based life prediction model for lithium-ion batteries with Ni-rich cathode materials

Sun Ho Park et al.

Summary: The accuracy of conventional battery life prediction models for lithium-ion batteries (LiBs) with Ni-rich cathode materials is greatly reduced as the nickel content increases due to the neglect of degradation parameters such as crack formation and propagation. In this study, an advanced prediction model that includes both crack propagation and solid electrolyte interphase (SEI) growth is proposed and verified using experimental data of over 50 commercial 18650 LiB cells. The proposed model predicts capacity retention values with less than 5% error, providing a standard solution for predicting the cycle life of LiBs with Ni-rich cathode materials even in practical operations.

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.
