摘要 高温固相反应方法合成了Li1-xNaxMn2O4锂离子电池正极材料。通过Na部分取代锰酸锂中的Li,期待能够弱化Jahn-Teller效应,提高锰酸锂的循环稳定性。实验结果证实了我们的预测。取代量为x=0.06时最佳。 The positive electrode material, Li1-xNaxMn2O4, has been synthesized via high temperature solid state reaction method. The weakened Jahn-Teller effect was expected via partial substitution of Li by Na to improve the cycle stability of LiMn2O4. The experimental results have confirmed our expectation. It is found that the optimum substitution is x=0.06.
