Special Issue Information

Dear Colleagues,

Lithium-ion battery electrode materials play a key role in determining the energy density, lifecycle, and safety performance of batteries, so it is imperative to study the positive and negative electrode materials of lithium-ion batteries. This Special Issue aims to briefly introduce the relevant knowledge of lithium-ion batteries, introduce their preparation in detail, improvement methods, and the electrochemical properties of various new lithium-ion battery positive- and negative-electrode materials, as well as briefly summarize the advantages and disadvantages of various electrode materials. It is expected that, in the future, the research and development of electrode materials will focus on the direction of high specific capacity, high charge–discharge efficiency, high cycle performance, and low cost. This Special Issue aims to report on and exchange the latest research progress in the field of electrode materials in lithium-ion batteries and provide theoretical and technical support for promoting the development of lithium-ion batteries.

Therefore, we invite scholars to submit articles related to this topic to share findings and insights on lithium-ion battery electrode materials.

As an efficient energy storage solution, lithium-ion batteries (LIBs) play a crucial role in the electric vehicle sector, driving innovation and development in the automotive industry. One common strategy to enhance energy density is to manufacture thicker electrodes. However, the pore distribution in thicker electrodes is often suboptimal, with elongated and tortuous pathways impeding charge transport. Optimizing the pore structure in electrodes is essential for fabricating high-performance batteries. In this study, we performed microwave sintering on lithium cobalt oxide materials and observed the three-dimensional evolution of pores during the sintering process using synchrotron radiation computed tomography (SR-CT).We discovered that pore evolution exhibits directional characteristics. Further analysis revealed that the electromagnetic loss of particles is related to the direction of the electric field, which is the reason for the directional behavior of pore evolution. This research could provide a new potential approach for the fabrication of advanced electrode materials by using electric field control during the battery manufacturing process to align pores vertically, thereby improving both the energy density and charge–discharge rate of the battery.

Lithium nickel manganese cobalt oxides (NMCs) are widely used as cathode materials in commercial batteries. Efforts have been made to enhance battery energy density and stability by adjusting the element ratio. Nickel-rich NMC shows promise due to its high capacity; however, its commercial viability is hindered by severe capacity fade, primarily caused by poor mechanical stability. To address this, understanding the chemo-mechanical behavior of Ni-rich NMC is crucial. The mechanical failure of Ni-rich NMC materials during battery operation has been widely studied through theoretical approaches to identify possible solutions. The elastic properties are key parameters for structural analysis. However, experimental data on NMC materials are scarce due to the inherent difficulty of measuring the properties of electrode active particles at such a small scale. In this study, we employ molecular dynamics (MDs) simulations to investigate the elastic properties of NMC materials with varying compositions (NMC111, NMC532, NMC622, NMC721, and NMC811). Our results reveal that elasticity increases with nickel content, ranging from 200 GPa for NMC111 to 290 GPa for NMC811. We further analyze the contributing factors to this trend by examining the individual components of the elastic properties. The simulation results provide valuable input parameters for theoretical models and continuum simulations, offering insights into strategies for reducing the mechanical instability of Ni-rich NMC materials.
