Li<i><sub>x</sub></i>MO<sub>2</sub>
materials, a new class of high-entropy oxides, have been synthesized by
nebulized spray pyrolysis. Specifically, the lattice structure of Li(Ni<sub>1/3</sub>Mn<sub>1/3</sub>Co<sub>1/3</sub>)O<sub>2</sub>
(NCM111) cathode material has been replicated successfully while increasing the
number of cations in equimolar proportions, thereby allowing transition to
high-entropy oxide materials.</p>
