Overview

Nanosized anatase TiO2 improves Mg2+ ion storage in batteries, indicating effective crystal facet control.

Key Points

  • Nanosized anatase TiO2 with exposed (001) facet demonstrated superior Mg2+ ion storage capacity.
  • The capacity reached was 312.9 mAh g-1 in Mg–Li dual-salt electrolyte, significantly higher than 234.3 mAh g-1 in Li salt electrolyte.
  • First-principles calculations revealed reduced diffusion energy barriers for Mg2+ on the (001) facet compared to other facets.
  • Controlling the crystal facet of nanocrystals can enhance the interfacial storage of multivalent ions effectively.
