MoSe2/Bi2Se3 Heterostructure Immobilized in N‐Doped Carbon Nanosheets Assembled Flower‐Like Microspheres for High‐Rate Sodium Storage

over 1400 cycles. Notably, the capacity can be fully restored to its initial level after cycling at high current densities. This study, combining experimental and theoretical insights, provides a novel perspective on interface engineering to advance the practical application of SIBs.
