Intensive research effort is currently focused on the development of efficient, reliable, and environmentally safe electrochemical energy storage systems due to the ever-increasing global energy storage demand. Li ion battery systems have been used as the primary energy storage device over the last three decades. However, low abundance and uneven distribution of lithium and cobalt in the earth crust and the associated cost of these materials, have resulted in a concerted effort to develop beyond lithium electrochemical storage systems. In the case of non-Li ion rechargeable systems, the development of electrode materials is a significant challenge, considering the larger ionic size of the metal-ions and slower kinetics. Two-dimensional (2D) materials, such as graphene, transition metal dichalcogenides, MXenes and phosphorene, have garnered significant attention recently due to their multi-faceted advantageous properties: large surface areas, high electrical and thermal conductivity, mechanical strength, etc. Consequently, the study of 2D materials as negative electrodes is of notable importance as emerging non-Li battery systems continue to generate increasing attention. Among these interesting materials, graphene has already been extensively studied and reviewed, hence this report focuses on 2D materials beyond graphene for emerging non-Li systems. We provide a comparative analysis of 2D material chemistry, structure, and performance parameters as anode materials in rechargeable batteries and supercapacitors.

由于全球储能需求不断增长，目前大量的研究工作集中在开发高效、可靠和环境安全的电化学储能系统上。在过去的三十年里，锂离子电池系统一直被用作主要的能量存储设备。然而，地壳中锂和钴的丰度低且分布不均匀，以及这些材料的相关成本，导致人们共同努力开发锂以外的电化学存储系统。对于非锂离子可充电系统，考虑到金属离子的离子尺寸较大和动力学较慢，电极材料的开发是一个重大挑战。二维（2D）材料，例如石墨烯、过渡金属二硫属化物、MXenes和磷烯，由于其多方面的优势特性（大表面积、高导电性和导热性、机械强度等）最近引起了人们的广泛关注。随着新兴的非锂电池系统不断引起越来越多的关注，二维材料作为负极的研究具有显着的重要性。在这些有趣的材料中，石墨烯已经得到了广泛的研究和审查，因此本报告重点关注石墨烯以外的新兴非锂系统的二维材料。我们对作为可充电电池和超级电容器阳极材料的二维材料化学、结构和性能参数进行了比较分析。
