Abstract

In this study, we synthesized spinel high-entropy oxide (HEO) (Cr0.2Mn0.2Co0.2Ni0.2Zn0.2)3O4 nanoparticles by a simple solution combustion method. These particles were investigated for their performance as anodes in lithium-ion batteries. The reversible capacity is 132 mAh·g−1 after 100 cycles at a current density of 100 mA·g−1, 107 mAh·g−1 after 1000 cycles at a current density of 1 A g−1, and 96 mAh·g−1 rate capacity at a high current density of 2 A g−1. The outstanding cycle stability under high current densities and remarkable rate performance can be attributed to the stable structure originating from the high entropy of the material.

作为锂离子电池负极材料的新型尖晶石高熵氧化物（Cr0.2Mn0.2Co0.2Ni0.2Zn0.2）3O4

在这项研究中，我们采用简单的溶液燃烧法合成了尖晶石高熵氧化物（HEO）（Cr0.2Mn0.2Co0.2Ni0.2Zn0.2）3O4 纳米粒子。研究了这些颗粒作为锂离子电池阳极的性能。在 100 mA-g-1 的电流密度下循环 100 次后，其可逆容量为 132 mAh-g-1；在 1 A g-1 的电流密度下循环 1000 次后，其可逆容量为 107 mAh-g-1；在 2 A g-1 的高电流密度下，其速率容量为 96 mAh-g-1。高电流密度下出色的循环稳定性和显著的速率性能可归因于材料的高熵产生的稳定结构。
