Abstract

Sodium titanate nanosheet arrays grown on titanium foil are utilized as a current collector for a lithium metal anode and Ti³⁺ is introduced by Ar/H₂ plasma for a uniform lithium deposition. The lithium nucleation overpotential and voltage hysteresis are dramatically reduced by increased active sites and improved electrical conductivity.
