Abstract:
Lithium (Li) dendrite growth seriously hinders the practical application of Li metal batteries. Here, we report molecular amidinothiourea (ATU) as a new electrolyte additive to regulate Li stripping/plating behaviors of Li metal anodes. The molecular ATU in the electrolyte can act as a shielding layer on the Li metal surface to suppress the decomposition of electrolytes as verified by XPS and adsorption energy calculation, which improves the electrochemical reversibility of the Li plating/stripping behaviors and inhibits lithium dendrite growth.

Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
