Al doped LiNi0.6Co0.3-xTi0.1AlxO2 cathode material via combustion method

Aluminium (Al) was doped into cobalt sites of LiNi0.6Co0.3Ti0.1O2 (LNCT) material, producing LiNi0.6Co0.29Ti0.1Al0.01O2, LiNi0.6Co0.27Ti0.1Al0.03O2 and LiNi0.6Co0.25Ti0.1Al0.05O2 cathode materials denoted as LCA1, LCA3 and LCA5 respectively. The synthesis of those materials were using self-propagati...

description Aluminium (Al) was doped into cobalt sites of LiNi0.6Co0.3Ti0.1O2 (LNCT) material, producing LiNi0.6Co0.29Ti0.1Al0.01O2, LiNi0.6Co0.27Ti0.1Al0.03O2 and LiNi0.6Co0.25Ti0.1Al0.05O2 cathode materials denoted as LCA1, LCA3 and LCA5 respectively. The synthesis of those materials were using self-propagating combustion method. The doping of Al is done to reduce the toxicity of Co element and to stabilize the cathode structure in order to increase the initial discharged capacity of the lithium-ion battery system. The characterization of the materials was done by using X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM). Based on the XRD results, all materials showed a single phase structure. Meanwhile, FESEM results revealed that all materials are polyhedral like shape but the Al doped materials have smaller crystallite size than the undoped material. The electrochemical performance of the battery system using the synthesized cathode were tested. According to the battery testing results, the initial discharged capacity of the Al doped battery were successfully increased.
