A strongly positive entropy of reaction for the bulk deposition of Li can be explained by the desolvation of Li + ions, as revealed by microcalorimetric studies. From this the coordination number of Li + can be derived. The positive entropy leads to cooling of the electrode, which may influence lithium plating in lithium‐ion batteries.
