The application of composite materials that combine the advantages carbonaceous material and metal alloy proves to be a valid method for improving performance lithium-sulfur batteries (LSBs). Herein iron-cobalt-nickel (FeCoNi) ternary nanoparticles (FNC) spread on nitrogen-doped carbon (NC) are obtained by strategy low-temperature sol-gel followed annealing at 800 °C under an argon/hydrogen atmosphere. Benefiting from synergistic effect different components FNC conductive network provided...
Metal sulfides are promising materials for sodium-ion batteries (SIBs) owing to unique structures and high theoretical capacity. However, issues like poor conductivity, large volume changes, polysulfide dissolution limit practical application.

The situ synthesis ensures excellent lattice...
Abstract Although memristor‐based in‐memory computing (IMC) prototypes demonstrate great progress and performance, integrating high flexibility programmability into large‐scale, high‐density crossbar arrays remain a major hurdle for advanced systems. Herein, the execution of 12 distinct algorithms is successfully implemented in single halide perovskite based IMC, leading to construction memory with reconfigurable logic operation capabilities.
