Abstract

The structural and electrochemical characteristics and the thermal behavior of four-cation oxides, LiNi_0.85Co_0.10M_0.05O₂ (M = Al, Fe) were examined by X-ray and neutron diffraction measurements, charge/discharge cycling and thermal analysis. LiNi_0.85Co_0.10Al_0.05O₂ showed enhanced electrochemical properties, i.e. a small polarization and a large reversible capacity during the charge/discharge cycling compared with LiNiO₂ and it is due to the structural stabilization of the nickelate in the wide range of x by Co and Al substitution. The substitution of Co, Al and Fe also had a beneficial effect on the thermal stability of LiNiO₂.
