"introducing additive to electrolyte stifles crosstalk. As additive decomposes... produces lithium phosphate (Li3PO4) and lithium fluoride (LiF) to form protective cathode-electrolyte-interphase—a solid thin layer... battery’s cathode during cycling... Reduced transition metal loss decrease deposition of transition metals on anode... enables a nickel-rich layered cathode to be cycled at high voltages to increase the energy density and still retain 97 percent of its initial capacity after 200 cycles, the researchers found"
