Graphene, versatile building blocks for functional composite materials, shows multiple fascinating properties and draws great interest, especially in the field of electrochemical energy storage. However, several common drawbacks still persist, including (i) it tends to aggregate and restack to loss the surface area, (ii) it is difficult to composite with other materials due to the limited processibility (e.g, limited functional groups or defect sites), (iii) it lacks efficient molecules/ions transport channels. Thus, it presents a great challenge to prepare graphene-based nanocomposites for various applications, including energy storage. However, the recent availability of holey graphene (HG) has led to numerous HG-based functional composites of practicle significance. This review presents a comprehensive overview of the synthesis of HG and its nanocomposites, and their applications for electrochemical energy storage, including supercapacitors, lithium ion/sulfur/O₂/CO₂ batteries, sodium ion batteries, potassium ion batteries, Zn-air batteries, fuel cells and solar cells. The structure-property relationships of various HG-based nanocomposites will be thoroughly discussed, along with the pros and cons. The current challenges and future perspectives of HG-based nanocomposites are also outlined. This review should promote the fundamental understanding and further development of HG-based nanocomposites for electrochemical energy storage and even beyond.

石墨烯是功能性复合材料的多功能构建基块，具有多种引人入胜的性能，引起了人们极大的兴趣，特别是在电化学储能领域。但是，仍然存在一些常见的缺点，包括（i）它倾向于聚集并重新堆积以损失表面积，（ii）由于可加工性有限（例如，功能基团或缺陷部位有限）而难以与其他材料复合（iii）缺乏有效的分子/离子传输通道。因此，制备用于包括能量存储的各种应用的基于石墨烯的纳米复合材料提出了巨大的挑战。然而，最近有孔的石墨烯（HG）的可用性已导致许多具有实用意义的基于HG的功能性复合材料。₂ / CO ₂电池，钠离子电池，钾离子电池，锌空气电池，燃料电池和太阳能电池。将详细讨论各种基于HG的纳米复合材料的结构-特性关系，以及优缺点。还概述了基于HG的纳米复合材料的当前挑战和未来前景。该综述应促进对基于HG的纳米复合材料进行电化学储能甚至更广泛的应用的基础理解和进一步的发展。
