Enhanced energy storage and rate performance induced by dense nanocavities inside MnWO4 nanobars

MnWO4 nanobars with dense nanocavities have been synthesized through a one pot hydrothermal route. Galvanostatic cycling of the MnWO4 lithium battery anode exhibits an excellent rate performance. The standout electrochemical performance could be attributed to the unique geometry nanocavities and improved accommodation of the transformation strains during cycling.
