The emergence of electric mobility has placed high demands on lithium-ion batteries, inevitably requiring a substantial consumption of transition-metal resources. The use of this resource raises concerns about the limited supply of transition metals along with the associated environmental footprint. Organic rechargeable batteries, which are transition-metal-free, eco-friendly and cost-effective, are promising alternatives to current lithium-ion batteries that could alleviate these mounting concerns. In this Review, we present an overview of the efforts to implement transition-metal-free organic materials as the redox-active component in diverse types of organic rechargeable batteries. In addition, we critically evaluate the current status of organic rechargeable batteries from a practical viewpoint and assess the feasibility of their use in various energy-storage applications with respect to environmental and economic aspects. We believe this Review provides a timely evaluation of organic rechargeable batteries from a real-world perspective, and we hope it will spur more intensive efforts towards a greener energy future.

电动汽车的出现对锂离子电池提出了很高的要求，不可避免地需要大量消耗过渡金属资源。这种资源的使用引起了人们对过渡金属供应有限以及相关环境足迹的担忧。有机可充电电池不含过渡金属、环保且具有成本效益，是目前锂离子电池的有前途的替代品，可以缓解这些日益严重的问题。在这篇综述中，我们概述了在各种类型的有机可充电电池中实施无过渡金属有机材料作为氧化还原活性成分的努力。此外，我们从实用的角度批判性地评估有机可充电电池的现状，并从环境和经济方面评估它们在各种储能应用中的可行性。我们相信，本次审查从现实世界的角度提供了对有机可充电电池的及时评估，我们希望它能推动更加深入的努力，朝着更绿色的能源未来发展。
