Effect of Residual Lithium Compounds on Layer Ni-Rich Li[Ni0.7Mn0.3]O2

In order to confirm reasons that deteriorate cathode performances, Ni-rich Li[Ni 0.7 Mn 0.3 ]O 2 is modified by lithium isopropoxide to artificially provide lithium excess environment by forming Li 2 O on the surface of active materials. X-ray diffraction patterns indicate that the lithium oxide coa... View More
