Overview

Review demonstrates enhanced electrochemical performance of titanium dioxide nanostructure anodes in lithium- and sodium-ion batteries, highlighting their potential for safer energy storage.

Key Points

  • To evaluate the electrochemical performance, safety benefits, and functional mechanisms of TiO2 nanostructures, particularly colloidal anatase mesocrystals, as anodes for lithium-ion and sodium-ion batteries.
  • Reviewed electrochemical properties of TiO2 polymorphs assembled into nanostructures to evaluate ion diffusion distances, contact density, and Na+ storage capability.
  • Assessed colloidal-sized TiO2 anatase mesocrystal negative electrodes operating in conventional alkyl carbonate electrolytes and safe ionic liquid electrolytes.
  • Nanostructured TiO2 reduced diffusion lengths, maximized contact interfaces, and provided supplementary sites for Na+ storage, improving overall power efficiency.
  • TiO2 anatase mesocrystals exhibited high textural quality and strong electrochemical performance as negative electrodes in both carbonate and ionic liquid electrolyte systems.
