| description | The invention relates to a preparation method and application of a high-entropy alloy modified lithium metal electrode, and belongs to the technical field of lithium metal battery negative electrodes. According to the method, a magnetron sputtering method is adopted, and a high-entropy alloy is used as a target material to be sputtered onto a lithium metal substrate. The high-entropy alloy modified lithium metal electrode is used as a battery negative electrode, a total battery assembled by matching with LFP still keeps high specific discharge capacity of 130mAh g after 300 cycles of charge and discharge at the rate of 1C, and the capacity retention ratio is 88%.
本发明涉及一种高熵合金改性的锂金属电极的制备方法及其应用，属于锂金属电池负极技术领域。所述方法采用磁控溅射法，将高熵合金作为靶材溅射到锂金属基底上。以所述高熵合金改性的锂金属电极作为电池负极，匹配LFP组装的全电池在1C倍率下，充放电循环300周仍保持130mAh g-1的高放电比容量，容量保持率为88％。 |
