Zwitterionic Electrolyte Additive for Lithium‐Ion Batteries: Ammonium Alkyl Sulfonate
Abstract
Abstract 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 LiCoO 2 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.
