CoSe2-SnSe2/NC nanocubes (CSNC@NC) coated by nitrogen-doped carbon (NC) were synthesized successfully by an ordinary pyrazole polymerization and carbonization process. In comparison with bare CSNC, the CSNC@NC composite exhibited good structural stability and improved electrical conductivity when used as anode. The CSNC@NC electrode showed a stable Li storage capacity (730.41 mAh g−1 over 100 cycles at 0.2 A g−1) and excellent rate performance (402.10 mAh g−1 at 2 A g−1). For Na storage, the discharge capacity could be maintained 279.3 mAh g−1 over 100 cycles at 0.2 A g−1; the lower capacity than that for Li storage maybe caused by the …

Sodium-ion batteries (SIBs) have been deemed a promising low-cost battery technology for grid-scale energy storage in view of the abundance of sodium resources. The large ionic size (1.02 Å) and different electronegativity of Na+ nevertheless, make it difficult to reversibly insert/extract into/out of most host materials, resulting in inferior battery performance. Searching for viable anode materials with high efficiency that can accommodate the Na+ while achieving long-term stable electrochemical performance is a tough issue for SIBs. With the characteristics of high theoretical capacity (335 mAh g-1), reasonable insertion voltage (~0.75 V vs. Na/Na+), chemical stability, and abundant reserves, titanium oxides …
