Electrolyte additive is an important component of lithium-ion batteries. At present, commercial film-forming additives can only work on either anode or cathode so as to increase the complexity and decrease the efficiency of the electrolyte. In this work, we designed and synthesized a novel zwitterionic 3-(triethylammonium)-propane-1-sulfonate (TEAPS) additive, which can adsorb on the surface of both graphite anode and LiCoO2 cathode in propylene carbonate (PC) electrolyte. The kinetically and thermodynamically favorable film-forming reaction of TEAPS promotes the formation of a robust F/S/N-species domain interface, thereby enables greatly improved cycling performance. It is believed that the zwitterionic TEAPS will work as a novel versatile additive for high-performance LIBs.

To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates...

02:54Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:

01:20Amides 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.
