An electrolyte additive allows stable high-voltage cycling of a nickel-rich layered cathode

Subjects

Using an electrolyte additive enables a nickel-rich layered cathode to be cycled at high voltages and still retain 97% of its initial capacity after 200 cycles. The decomposition of the electrolyte additive leads to the formation of a robust interphase that protects the surface of the cathode, preserving the capacity and preventing cracks.
