Scaly MoS₂/rGO Composite as an Anode Material for High-Performance Potassium-Ion Battery.

ABSTRACT: Potassium-ion batteries (PIBs) have been widely studied owing to the abundant reserves, widespread distribution, and easy extraction of potassium (K) resources. Molybdenum disulfide (MoS₂) has received a great deal of attention as a key anode material for PIBs owing to its two-dimensional diffusion channels for K⁺ ions. However, due to its poor electronic conductivity and the huge influence of embedded K⁺ ions (with a large ionic radius of 3.6 Å) on MoS₂ layer, MoS₂ anodes exhibit a poor rate performance and easily collapsed structure. To address these issues, the common strategies are enlarging the interlayer spacing to reduce the mechanical strain and increasing the electronic conductivity by adding conductive agents. However, simult
