Summary: The synthesis of metastable olivine phase NaMnPO4 presents a challenge, but in this study, single crystals of olivine NaMnPO4 were successfully synthesized through a simple hydrothermal reaction. X-ray diffraction analysis provided precise structure information, and the metastable nature of the olivine phase was confirmed through transformation to the maricite phase. Furthermore, the olivine NaMnPO4 showed promising electrochemical performance as an anode material for Li-ion batteries, delivering a high capacity and good cycling stability, while the maricite phase NaMnPO4 exhibited low lithium storage capacity.

Summary: Carbon-rich SiOC-I and silicon-rich SiOC-II were synthesized and their elemental and structural characteristics were evaluated. The composite anode (SiOC-II/GNP) achieved high specific capacity (744 mAh/g) and excellent cycling stability. The enhanced electrochemical performance was attributed to better electronic conductivity, lower charge-transfer resistance, and short ion diffusion length.

Summary: In this study, the effect of slurry pH on the lithiation mechanism of silicon nanoparticle anodes in lithium-ion batteries was investigated using a combination of NMR, DFT, and electrochemical cycling. The results showed that the lithiation mechanisms varied depending on the pH. An acidic slurry promoted the lithiation of silicon nanoparticles, while a basic slurry oxidized the nanoparticles to form a SiO/SiO2 shell that needed to be cracked before Si lithiation. The reaction of Li+ and SiO/SiO2 to form lithium silicates was the dominant process in a basic slurry, resulting in greater capacity loss compared to an acidic slurry.

Summary: Niobium-based anode materials show promise for use in lithium-ion batteries due to their high specific capacity and safety. However, their low electronic conductivity limits their performance. In this study, a mixed-valent niobium-based phosphate, K3Nb6P4O26@C, was developed as an anode material. The mixed-valent Nb in KNPO enables multi-electron reactions and higher electronic conductivity. The 3D channels in the crystal structure of KNPO facilitate rapid lithium-ion transport. KNPO@C anode demonstrates a high specific capacity and excellent cycling stability, making it a potential practical material for high-performance LIBs.
