Sodium-Ion Batteries: An Advanced MoS₂/Carbon Anode for High-Performance Sodium-Ion Batteries (Small 4/2015)

The working principle of sodium-ion batteries is depicted by C. Wang and co-workers, who use molybdenum disulfide/carbon nanoflowers as an anode material and sodium metal as a counter electrode. Their devices demonstrate the best cycling performance of MoS2 for Na-ion batteries reported so far. The characteristic layered structure of MoS2 is shown in the bottom right of the main image, and the reversible conversion mechnism of MoS2 during sodiation/desodiation is confirmed on page 473.
