Abstract
- The development of high‐performance sodium ion batteries (SIBs) is heavily relied on the exploration of the appropriate electrode material for Na+ storage, which ought to feature merits of high capacity, easy‐to‐handle synthesis, high conductivity, expedite mass transportation, and stable structure upon charging–discharging cycle. Herein, a universal source‐template method is reported to synthesize a variety of transition metal (e.g., V, Sb, W, Zn, Fe, Co, Ni, and Cu) selenides implanting on N doped 3D carbon nanoarchitecture hybrids (MmSen@3D‐CN) with powerful SeC bonding rivet. Benefiting from the superior architecture and potent SeC bonding between Cu2−xSe and N‐doped 3D carbon (3D‐CN), the Cu2−xSe@3D‐CN nanohybrids, as anode of SIBs, show high capacity, high‐rate capability, and long‐cycle durability, which can deliver a reversible capacity of as high as 386 mAh g−1, retain 219 mAh g−1 even at 10 A g−1, and run durably over thousands of charging–discharging cycles. The Cu2−xSe@3D‐CN as anode is also evaluated by developing a full SIB by coupling with the Na3V2(PO4)3 cathode, which can deliver high energy density and show excellent stability, shedding light on its potential in practical application.
