氧化锌作为锂离子电池负极材料的研究进展

氧化锌作为锂离子电池负极材料具有理论比容量高(978 mAh/g),来源广,环境友好和价格便宜等优势,是新一代高效环保的锂离子电池负极材料之一。然而氧化锌电极材料固有的电导率较低,不利于电池大电流充放电。并且在循环充放电过程中,易产生枝晶及周期性应力,导致材料体积膨胀或结构损坏,致使电池的循环性能衰减过快,容量保持率低。本文综述了改善氧化锌电化学性能的两种常用的策略：制备不同维度具有纳米结构的氧化锌电极材料；与碳材料、金属单质和金属氧化物等复合制备氧化锌复合电极,并对该类负极材料进一步研究、应用前景予以展望。

Research progress of zinc oxide as anode materials for lithium-ion battery

As the anode electrode material for lithium-ion batteries, zinc oxide has the advantages of high theoretical specific capacity (978 mAh/g), abound resources, environmental friendliness, and low cost. It is one of the new generations of high-efficiency and environmentally friendly anode electrode materials for lithium-ion batteries. However, the inherent conductivity of the zinc oxide is low, which is not conducive to the high-current charging and discharging of the battery. In addition, during the cycle of charging and discharging, dendrites and periodic stress are prone to occur, resulting in material volume expansion or structural damage. As a result, the cycle performance and the capacity retention rate of the battery decays rapidly. This article summarizes two commonly used strategies for improving the electrochemical performance of zinc oxide: preparing zinc oxide electrode materials with nanostructures in different dimensions; preparing zinc oxide composite electrodes by combining with carbon materials, metal, or metal oxides. Further research and application prospects of anode materials are expected.
