Abstract A layered-nanospaced-confinement strategy was used to prepare tin/carbon nanosheet in the interlayers of layered double hydroxides (LDHs) as a confined space. The Sn nanodots with a small size of ~ 3 nm were embedded uniformly in the thin-layer carbon nanosheets. This tin/carbon nanosheet was served as anode materials, which can effectively alleviate the structure damage caused by volume expansion, and deliver a stable reversible specific capacity of 1570 mAh g−1 for lithium-ion batteries (LIBs) and 672 mAh g−1 for sodium-ion batteries (SIBs), which is much higher than that of traditional graphite anode (~372 mAh g−1).
