摘要
柔性电化学储能器件技术是支持柔性电子设备,如可穿戴设备等发展的关键技术,也是电化学储能领域中重要的发展方向。本文从柔性电化学储能器件的电极材料(碳纳米管、石墨烯、碳纸/碳纤维、织物等)、电解质(液态、固态、有机-无机复合电解质)、制造工艺(打印/涂覆/喷涂、沉积、纺织)及具有不同附加功能特性的新型柔性电池等方面对柔性电化学储能器件关键组元和技术的发展情况进行了综述。总体而言,作为处于研究起步阶段的技术,柔性电化学储能器件技术的主要发展方向在于在保证与应用情景(柔性、弯折等)相适应的力学性能的前提下,改善器件的功能特性(质量/体积能量密度、质量/体积功率密度、循环寿命、稳定性)与工业规模化生产适宜度。作为兼具结构-功能特性,应用前景广阔的储能技术分支,可以预见,柔性电化学储能器件技术在今后相当长的一段时间之内将持续为众多研究者所关注,并不断取得研究进展。
Flexible electrochemical energy storage is the key technology supporting the development of flexible electronics （like wearable smart electronic devices） and is regarded as the important R＆D direction for future electrochemistry. This article reviewes the state of art of the flexible electrochemical energy storage devices, and introduced the key components and current technology by specifying issues in terms of flexible electrode materials （CNT, graphene, carbon cloth/fiber, textiles）, electrolytes（liquid, solid, inorganic/organic composite）, fabrication techniques（printing, coating and spraying, deposition and weaving） and novel flexible electrochemical energy storage devices with more additional functional versatilities. Generally speaking, flexible electrochemical energy storage technologies are still in the initial stage. The fundamental prerequisite for its future development is maintaining its mechanical performance and service life under corresponding application circumstances （like bending and twisting）.The future R＆D emphasis will be mainly focused on elevating its performance including gravimetric/volumetric energy density and power density, service life, stability and development of novel energy storage devices with more functionalities and technologies suitable for scale-up mass production. Since flexible electrochemical energy storage technology combines both structural and functional advantages, it can be foreseen that it will draw constant attention for a long time in future and more R＆D progress will be expected.
