摘要

研究了Ti掺杂对锂离子电池正极材料Li1.2(Mn0.67Ni0.17Co0.15Ti0.02)0.8O2功能性能的影响。该氧化物是通过适当的碳酸盐前驱体的共沉淀和固相反应合成的。在过渡金属位点掺杂2 at %钛，提高了材料能量，改善了材料的循环性能。在循环过程中，获得了有利于正极材料中发生的动力学的正掺杂效应的证据。

Effect of Titanium Doping of Lithium-Rich Cathode Materials

The influence of Ti doping on the functional properties of the lithium-rich Li_1.2(Mn_0.67Ni_0.17Co_0.15Ti_0.02)_0.8O₂ cathode material for lithium-ion batteries was studied. The oxide was synthesized by co-precipitation of the appropriate carbonate precursor followed by a solid-state reaction. Doping 2 at % titanium in the transition metal sites increased the material energy and improved its cycling performance. Evidence in favor of positive doping effect on the kinetics of the processes occurring in the cathode material during cycling was obtained.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
