Phenylphosphonic acid as a grain-refinement additive for a stable lithium metal anode†
Abstract
Phenylphosphonic acid (PPOA) has been proposed as a new additive for carbonate electrolytes, in which the complexation reaction between PPOA and Li+ reduces the nucleus size and boosts the nucleation quantity during the plating process. Thus, enhanced cycling stability is obtained in both symmetric cells and full cells.
