Super-short carbon nanotubes with uniform and molecular scale length, which can be regarded as carbon nanorings (CNRs), are difficult to obtain from long carbon nanotubes. Wensheng Yang and co-workers report on page 1125 a strategy for fabricating CNRs with ∼1 nm length in the confined interlayer galleries of a layered double hydroxide which exhibit excellent lithium storage performance under high-rate charge and discharge.
