The Structure and Electrochemical Performance of LiNi0.3Co0.3Mn0.3Cr0.1O2 Cathode Materials

Normal 0 false false false MicrosoftInternetExplorer4 Layered cathode materials are important for Li-ion battery application due to their high theoretical specific capacity. Efforts have been made to synthesize mixed-metal cathode materials such as LiNi1/3Co1/3Mn1/3O2 based materials with promising electrochemical characteristics. This is to lower the expensive Co content and help to stabilize the materials. Substitution of these materials with chromium producing LiNi0.3Co0.3Mn0.3Cr0.1O2 material will also improve the stability of the cathodes. In this work, pure and single phase LiNi0.3Co0.3Mn0.3Cr0.1O2 material was successfully synthesized using a combustion method. The samples were then annealed at 900 °C for 24, 48 and 72 h. From the charge-discharged measurements, it was found that the performance of the LiNi0.3Co0.3Mn0.3Cr0.1O2 cathode material annealed at 900 °C for 24 h shows the best performance. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}
