Chloride ion battery (CIB) is considered as one of the potential objects to replace lithium ion battery because of its high discharge platform and high theoretical capacity. However, traditional CIB still has many problems because it can not solve the problem of matching the positive and negative active materials with the electrolyte. The main performance is poor cycle life, and low battery capacity, and it cannot meet the needs of real life. In our work, we first propose the application of graphite paper as cathode material and aqueous electrolyte in CIB, and reconstruct a new system of CIB. With zinc anode, the cycle life of the battery is more than 4000 times, and the cycle life of the electrolyte is more than 10,000 times under the promotion of lithium salt. At the same time, we synthesize flexible-solid-electrolyte, and first assemble flexible CIB, which broadens the application field of CIB. The breakthrough of flexible chloride ion battery changes the structure of the battery, which can be applied to the car as a part of the car shell to save the material cost. Secondly, chloride ion battery in high temperature environment do not produce safety hazards, which greatly improves the safety.

一种可改变电动汽车结构的新型氯离子电池

氯离子电池(CIB)因其高放电平台和高理论容量而被认为是替代锂离子电池的潜在对象之一。但是,传统的CIB由于不能解决正负极活性物质与电解液的匹配问题,仍然存在很多问题。主要表现是循环寿命差,电池容量低,不能满足现实生活的需要。在我们的工作中,我们首先提出将石墨纸作为阴极材料和水性电解质在 CIB 中的应用,并重建了一个新的 CIB 体系。采用锌阳极,电池循环寿命4000次以上,电解液在锂盐推动下循环寿命10000次以上。同时,我们合成柔性固体电解质,并首次组装柔性CIB,拓宽了CIB的应用领域。柔性氯离子电池的突破改变了电池的结构,可作为车壳的一部分应用于汽车,节省材料成本。其次,氯离子电池在高温环境下不会产生安全隐患,大大提高了安全性。
