Gram-scale synthesis of ultrasmall SnO2 nanocrystals with an excellent electrochemical performance

The gram-scale synthesis of ultrasmall SnO2 nanocrystals has been successfully realized via a solvothermal process, during which the solvent used plays an important role in inhibiting the growth and aggregation of the nanocrystals. When investigating their electrochemical behaviour, the nanocrystal electrode shows an excellent performance in capacity retention and a better rate capacity.
