The
LiMn<sub>1.5</sub>Ni<sub>0.5</sub>O<sub>4</sub> spinel is an important
lithium ion battery cathode material that has continued to receive
major research attention because of its high operating voltage (∼4.8
V). This study interrogates the impact of microwave irradiation on
the Mn<sup>3+</sup> concentration and electrochemistry of the LiMn<sub>1.5</sub>Ni<sub>0.5</sub>O<sub>4</sub> spinel. It is shown that microwave
is capable of tuning the Mn<sup>3+</sup> content of the spinel for
enhanced electrochemical performance (high capacity, high capacity
retention, excellent rate capability, and fast Li<sup>+</sup> insertion/extraction
kinetics). This finding promises to revolutionize the application
of microwave irradiation for improved performance of the LiMn<sub>1.5</sub>Ni<sub>0.5</sub>O<sub>4</sub> spinel, especially in high
rate applications.
