Summary: Lithium titanate (LTO) anodes are preferred in lithium-ion batteries due to their durability and performance at different temperatures. This study investigates the effect of extreme temperatures on the electrical and electrochemical properties of LTO anodes. The capacity and C-rate performance of LTO anodes improve up to 70 degrees C, but deteriorate at temperatures above 80 degrees C and eventually fail at 130 degrees C. The results suggest that within a certain range, increasing temperature can facilitate faster charging of lithium-ion cells by improving rate capability and discharge capacities of LTO anodes.

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.

Summary: In recent years, there has been intense competition in the development of cathode materials for rechargeable Al batteries due to their excellent safety performance and high theoretical specific capacity. The yolk-shell structure in cathode material design offers ample storage space and abundant active sites, which synergistically contribute to the creation of high-performance cathode structures. The construction of a MoS2/NiS@S heterojunction interface effectively enhances the conductivity of monometallic sulfide as a cathode and improves the electrode's discharge performance. The surface folds and pores of the heterojunction provide excellent pathways for the insertion and release of Al3+, reducing binding energy and enhancing Al3+ binding efficiency. After 2000 cycles at 500 mA g-1, a reversible capacity of 130.19 mAh g-1 has been maintained. This offers additional insights for the development of transition metal sulfide materials in Al batteries.
