Summary: Silicon (Si) anodes are expected to be used in lithium-ion batteries (LIBs) in the future due to their high capacity. However, the main challenge is to assemble Si with conductive materials to improve the conductivity and stability of Si anodes. This study optimized a method to prepare Si nanoparticles (NP)/MXene anode materials for LIBs through electrostatic assembly of positively charged Si nanospheres coated with poly-diallyl dimethyl ammonium chloride and negatively charged MXene nanosheets, which increased the active sites for Si NP attachment and reduced restacking of MXene nanosheets and Si NP aggregation. The Si NP/MXene anodes exhibited a capacity of 1917.9 mA h g-1 after 300 charge/discharge cycles at 0.5 A g-1, indicating high energy storage, cycle stability, and rate performance. Optimization of Si/MXene composites can enhance their performance as anode materials for high energy density LIBs.

Summary: Researchers synthesized a unique ternary hybrid structure of SnS2 nanosheets and SnO2 particles on graphene aerogels by hydrothermal method. The SnO2/SnS2/SGA exhibited better cycling stability compared to SnS2/GA and SnO2/GA, and the tight adhesion between SnO2 and SnS2 helped alleviate material destruction caused by volume expansion. Furthermore, SnO2 and SnS2 anchored on graphene aerogels showed reversible conversion reaction and benefited from synergistic effect. The reversibility during the transition was confirmed by ex-situ high-resolution transmission electron microscopy. The SnO2/SnS2/SGA hybrid exhibited enhanced electrochemical capability.
