This is because of Ni2+<\/sup>\/Ni4+<\/sup> redox couple with a voltage plateau at 4.7 V (vs.<\/em> Li\/Li+<\/sup>). Additionally, the excellent rate capabilities of LNMO makes it ideal for high-power applications. However, due to high voltage operation, the instability of conventional electrolytes (aprotic carbonates with LiPF6<\/sub> salt) causes interfacial reactions accompanied by transition metal dissolution, especially at elevated temperatures, leading to rapid capacity fading. To address the above given issues, EC (ethylene carbonate)-free electrolytes could be employed since EC based electrolytes experience poor stabilities at higher potentials.

We will present our latest results on studying EC-free electrolytes for LNMO based cells. Electrochemical measurements of LNMO based cells, in which different types of counter-electrodes were used, will be discussed. <\/p>\n\n\n\n
