The Structure and Electrochemical Performance of LiNi_0.3Co_0.3Mn_0.3Cr_0.1O₂ Cathode Materials

Abstract:

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 LiNi_1/3Co_1/3Mn_1/3O₂ 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 LiNi_0.3Co_0.3Mn_0.3Cr_0.1O₂ material will also improve the stability of the cathodes. In this work, pure and single phase LiNi_0.3Co_0.3Mn_0.3Cr_0.1O₂ 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 LiNi_0.3Co_0.3Mn_0.3Cr_0.1O₂ 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;}
