Boron (B)-doped LiNi0.6Co0.2Mn0.2O2 cathode materials were prepared by oxalate co-precipitation and subsequent heat treatment. The effects of doping with different boron sources (B2O3, H3BO3 and LiBO2) on the morphology, structure and electrochemical properties of the materials were investigated. The X-ray diffracation and Rietveld refinement revealed that the B element was successfully doped into the material lattice. The electrochemical performance characterization showed that the doping effect of B2O3 was the best, with excellent rate performance (the specific discharge capacity was 145.1 mA·h/g at 5 C) and long-term cycle stability (the capacity retention ratio was 84.5% after 300 cycles at 1 C). The enhanced electrochemical performance is attributed to the fact that boron doping effectively reduces the surface residual lithium compound, enhances the structural stability of the material, effectively inhibits the voltage drop and improve the polarization phenomenon, and reduces the charge transfer resistance, thus inhibiting the capacity decay and achieving excellent electrochemical performance.

采用草酸盐共沉淀法结合后续热处理技术制备硼掺杂LiNi0.6Co0.2Mn0.2O2正极材料。研究了不同硼源(B2O3,H3BO3和LiBO2)掺杂对材料形貌、结构和电化学性能的影响。通过X射线衍射仪和Rietveld精修分析证明了硼(B)元素掺杂到材料晶格中。电化学性能研究表明:B2O3掺杂效果最佳,具有优异的倍率性能(5 C的放电比容量为145.1 mA·h/g)和长循环稳定性(1 C循环300圈容量保持率为84.5%),这归功于硼掺杂可有效减少表面残余锂化合物,提高了材料的结构稳定性,有效抑制了电压降和改善了极化现象,降低了电荷转移电阻,从而抑制了容量的衰减,实现了优异的电化学性能。

采用草酸盐共沉淀法结合后续热处理技术制备硼掺杂LiNi0.6Co0.2Mn0.2O2正极材料。研究了不同硼源(B2O3,H3BO3和LiBO2)掺杂对材料形貌、结构和电化学性能的影响。通过X射线衍射仪和Rietveld精修分析证明了硼(B)元素掺杂到材料晶格中。电化学性能研究表明:B2O3掺杂效果最佳,具有优异的倍率性能(5 C的放电比容量为145.1 mA·h/g)和长循环稳定性(1 C循环300圈容量保持率为84.5%),这归功于硼掺杂可有效减少表面残余锂化合物,提高了材料的结构稳定性,有效抑制了电压降和改善了极化现象,降低了电荷转移电阻,从而抑制了容量的衰减,实现了优异的电化学性能。

Boron (B)-doped LiNi0.6Co0.2Mn0.2O2 cathode materials were prepared by oxalate co-precipitation and subsequent heat treatment. The effects of doping with different boron sources (B2O3, H3BO3 and LiBO2) on the morphology, structure and electrochemical properties of the materials were investigated. The X-ray diffracation and Rietveld refinement revealed that the B element was successfully doped into the material lattice. The electrochemical performance characterization showed that the doping effect of B2O3 was the best, with excellent rate performance (the specific discharge capacity was 145.1 mA·h/g at 5 C) and long-term cycle stability (the capacity retention ratio was 84.5% after 300 cycles at 1 C). The enhanced electrochemical performance is attributed to the fact that boron doping effectively reduces the surface residual lithium compound, enhances the structural stability of the material, effectively inhibits the voltage drop and improve the polarization phenomenon, and reduces the charge transfer resistance, thus inhibiting the capacity decay and achieving excellent electrochemical performance.
