Abstract

Herein, a CuSe/MnSe₂ heterostructure with Se vacancies is fabricated as an ultrafast anode for low-temperature sodium-ion batteries. It achieves 380.3 mAh g⁻¹ after 1500 cycles (3.0 A g⁻¹) and 403.6 mAh g⁻¹ at −30 °C (0.5 A g⁻¹), highlighting exceptional cyclability and low-temperature adaptability.
