摘要
The deposition of Li-Na alloys from an ionic liquid medium has been demonstrated and evaluated with respect to dendrite growth, oxidation potential, and stability. The maximum coulombic efficiency for the reoxidation of the Li-Na alloy was found to be 91%. The conductivity of the ionic liquid medium containing the alloy salts was 364-466 mu S/cm(2). Upon addition of sodium to the lithium-ion electrolyte, a Li-Na alloy was deposited (mA/cm(2) current density range) that appears to suppress dendrite formation. (c) 2006 The Electrochemical Society.
