尽管碳质材料被广泛用作锂离子电池的商业负极，但仍迫切需要满足高能量密度、长循环寿命、低成本和安全性的新电极材料。许多钴基化合物（Co（OH）2、Co3O4、CoN、CoS、CoP、NiCo2O4等）由于其高的理论容量、丰富的氧化还原反应和足够的循环性能，在过去的几年中被开发为有希望的锂离子电池（LIB）负极材料。近年来，钴基化合物的LIB性能得到了显著改善，预计这些材料将在不久的将来成为实际应用的现实。然而，不同类型的钴基化合物将导致不同的电化学性能。本文简要分析了该领域的最新研究进展，重点介绍了各种钴基化合物的合成方法、制备的纳米结构及其在锂离子电池中的存储容量、倍率性能、循环稳定性等性能。
Despite carbonaceous materials are widely employed as commercial negative electrodes for lithium ion battery, an urge requirement for new electrode materials that meet the needs of high energy density, long cycle life, low cost and safety is still underway. A number of cobalt-based compounds (Co(OH)2, Co3O4, CoN, CoS, CoP, NiCo2O4, etc.) have been developed over the past years as promising anode materials for lithium ion batteries (LIBs) due to their high theoretical capacity, rich redox reaction and adequate cyclability. The LIBs performances of the cobalt-based compounds have been significantly improved in recent years, and it is anticipated that these materials will become a tangible reality for practical applications in the near future. However, the different types of cobalt-based compounds will result in diverse electrochemical performance. This review briefly analyzes recent progress in this field, especially highlights the synthetic approaches and the prepared nanostructures of the diverse cobalt-based compounds and their corresponding performances in LIBs, including the storage capacity, rate capability, cycling stability and so on.
