In situ construction of one-dimensional porous MnO@C nanorods for electrode materials
Owing to cost-effectiveness, low conversion potential, and high theoretical capacity (756 mA h g −1 ), MnO has been a potential candidate for LIB anode. Herein, a facile carbon modification route to prepare MnO@C nanorods with excellent capacity and long lifespan for LIB anode is presented, using Mn...

after 300 cycles at 2 A g

. The discharge capacity at 5 A g

was 261 mA h g
