Combining 5 V LiNi0.5Mn1.5O4 spinel and Si nanoparticles for advanced Li-ion batteries

An advanced high-voltage Li-ion battery is reported. The electrodes are prepared from a lithium–nickel–manganese spinel as cathode and silicon nanoparticles as anode. The specific capacity as referred to the anode material is 1700 mA h g−1, which is much higher than the reported values for most existing Li-ion batteries.
