Summary: First-principles computational studies under density functional theory (DFT) framework were conducted to investigate the structural stability, conductivity, and voltage profile of LiFe1-nNnP1-mMmO4(N, M = Si or S) electrode materials. It was found that the LiFeP7/8Si1/8O4 system exhibited the most stable structure, with gradually decreasing band gap values after doping. The LiFeP7/8Si1/8O4 system demonstrated n-type semiconductor characteristics, while other doping systems showed p-type semiconductor features.

Summary: Layered cathode materials, such as LiCoO2, have been synthesized for Li-ion batteries using a direct solution-calcination strategy. The addition of polyvinylpyrrolidone (PVP) as a functional agent in the synthesis process helps to eliminate surface Li residues and promote a uniform particle distribution. The solution-calcined cathode material shows improved cycling stability and rate capability compared to commercial LCO, with suppressed phase transition. This research provides a simple and versatile method for the synthesis of cathode materials, avoiding complicated steps and the formation of unwanted residual lithium compounds.

Summary: The study found that thermal stability of NCM cathode materials is influenced by nickel content and particle structure, with higher nickel content and polycrystal structure showing worse thermal stability. Increasing nickel content leads to a decrease in thermal reaction temperature and activation energy, while polycrystal materials exhibit a slight decrease in activation energy compared to single-crystal materials, with an increase in total enthalpy.

Summary: The focus of lightweight refractory is to replace high-density raw materials with lower-density raw materials in order to achieve equivalent volume replacement. In this study, porous mullite microspheres (PMM) were used to replace mullite particles in the preparation of mullite-cordierite saggars for Li-ion battery cathode materials. Various tests, including mechanical properties, thermal shock stability, and corrosion resistance, were conducted to confirm the quality standards of lightweight saggars. Compared to the samples with mullite particles, samples with PMM exhibit a more stable material structure and excellent performance, reducing mullite consumption and enhancing resistance to stress shedding during corrosion.

Summary: The research demonstrates that layered Li-rich cathode materials with higher intralayer configuration entropy exhibit superior local structural adaptability, effectively suppressing capacity degradation and voltage decay. After 3 months of cyclic testing, the energy retention of the entropy-stabilization-strategy-enhanced materials is almost twice that of typical materials. When cycled at 1 C, the voltage degradation per cycle is extremely low, demonstrating excellent performance.

Summary: A specially designed experimental device was used to investigate the corrosion of mullite during the calcination of LNCM materials. The influence of temperature on the interaction between mullite insulation materials and LNCM materials was determined. Additionally, the high-temperature creep properties of mullite insulation materials before and after corrosion were tested. The research provides a comprehensive understanding of the evolution of mullite insulation materials during the roasting process of LNCM materials, highlighting the importance of selecting materials with excellent resistance to alkali and Li+ corrosion for upgrading kiln linings in the lithium battery industry.

Summary: Rechargeable lithium-metal batteries have been considered as attractive energy-storage systems, and this study investigates the effects of several parameters in ether-based electrolytes on the SEI properties and capacity losses. It was found that cells with 1:1 DME:DOL + 2 M LiTFSI and 0.15 M LiNO3 electrolyte composition present the best cycling performance at low current densities, whereas under higher current conditions, the cell based on 1:1 DME:DOL + 2 M LiTFSI without the LiNO3 additive performs the best.

Summary: The phyllosilicate family of clays with layered topology and tunable composition is an ideal model for studying alkali ion intercalation. This study presents a hydrothermal method to prepare a layered iron phyllosilicate clay and evaluates its electrochemical performance for Li ion (de)insertion. Results show reversible insertion of lithium into interstitial layers via a solid solution mechanism. Comparison with other clay systems demonstrates the importance of controlling net charge on the layers for reversible cationic intercalation.

Summary: We conducted a comparative study on the magnetic and crystal chemical properties of two Co2+-containing garnets. It was found that CaY2Co2Ge3O12 and NaCa2Co2V3O12 exhibited different magnetic structures and properties under similar external conditions. Crystal-chemistry analyses and density functional theory calculations were performed to explain these differences based on minor changes in the local environment of the Co ions.
