The emerging demand for electronic and transportation technologies has driven the development of rechargeable batteries with enhanced capacity storage. Especially, multivalent metal (Mg, Zn, Ca, and Al) and metal-ion batteries have recently attracted considerable interests as promising substitutes for future large-scale energy storage devices, due to their natural abundance and multielectron redox capability. These metals are compatible with nonflammable aqueous electrolytes and are less reactive when exposed in ambient atmosphere as compared with Li metals, hence enabling potential safer battery systems. Luckily, green and sustainable organic compounds could be designed and tailored as universal host materials to accommodate multivalent metal ions. Considering these advantages, effective approaches toward achieving organic multivalent metal and metal-ion rechargeable batteries are highlighted in this Review. Moreover, organic structures, cell configurations, and key relevant electrochemical parameters are presented. Hopefully, this Review will provide a fundamental guidance for future development of organic-based multivalent metal and metal-ion rechargeable batteries.
对电子和运输技术不断增长的需求推动了具有增强储能能力的可充电电池的发展。特别是，多价金属（镁、锌、钙和铝）和金属离子电池最近作为未来大规模储能设备的有前途的替代品引起了相当大的兴趣，这是由于它们的天然丰度和多电子氧化还原能力。与锂金属相比，这些金属与不可燃水性电解质兼容，并且在暴露于环境大气中时反应性较低，因此有可能实现更安全的电池系统。幸运的是，可以设计和定制绿色可持续的有机化合物作为通用主体材料来容纳多价金属离子。考虑到这些优点，本综述重点介绍了实现有机多价金属和金属离子可充电电池的有效方法。此外，还介绍了有机结构、电池配置和关键相关电化学参数。希望本综述将为未来基于有机的多价金属和金属离子可充电电池的发展提供基本指导。
