- •
Core–shell MnO@C nanowires with internal void spaces are fabricated.
- •
LiMn2O4∥MnO@C full cell deliver a high energy density of 397 Wh kg−1.
- •
The full cell retains 215 Wh kg−1 even at a high power density of 6.2 kW kg−1.
- •
The full cell sustains a long lifetime with 13% capacity loss over 1000 cycles.
