Abstract
The development of nonflammable electrolytes can boost energy density and battery safety, especially for layered metal oxide cathodes operating at high voltage. However, most nonflammable electrolytes are designed in a high concentration for compatibility with graphite electrodes and/or less decomposition. Herein, we introduced a solvation structure-mediated model to develop a nonflammable electrolyte based on trimethyl phosphate (TMP) solvent at a normal concentration. This advancement allows the graphite || lithium cobalt oxide full cell to operate at 4.5 V, delivering high energy density and also exhibiting a nonflammable feature. This achievement is realized using previously unreported components,…
