We illustrate the yolk–shell structure of SnSe ₂ @NC, highlighting its robust architecture for stable sodium storage. At a high current density of 5 A g ⁻¹ , it delivers an impressive capacity, demonstrating its superior performance as an SIB anode.

In this work, PbPd_0.9V_0.1O₂ and PbPd_0.9Gd_0.1O₂ films with (002) preferred orientation were prepared using a pulsed laser deposition technique. The positive CER effect were found in V and Gd doped films, and its physical mechanism was investigated.

The SnO₂/Sn₄P₃ heterojunctions encapsulated within hierarchical carbon frameworks generate a built-in electric field, while the dual-carbon confinement buffers mechanical strain and guides LiF-rich SEI formation.
