This article aims to review the recent advances in electronic fibers/textiles, thus providing a comprehensive guiding reference for the future work. Among various types of wearable electronics, electronic fibers/textiles, which integrate the comfort and appearance of conventional fibers/textiles with the functions of electronic devices, are expected to play important roles in remote health monitoring, disease diagnosis/treatment and human-machine interface. Wearable electronics are receiving increasing attention with the advances of human society and technologies. Thermal management strategies, daily operation, early warning, and fire control are all vital parts for the safe operation and running of an electrochemical energy storage system. Safety materials is the primary factor, and battery‐ and system‐level designs are critical for better electrochemical and thermal performance. Thermal safety of electrochemical energy storage system is a series of work (from materials to system prospectives). For all kinds of batteries, thermal safety is the primary aspect to be considered before utilization. Lithium‐ion batteries are used as the current main electrochemical energy storage devices, and lithium–sulfur and lithium–air batteries could be promising candidates for future electrochemical energy storage. Moreover, the corresponding solutions are proposed to further improve the thermal safety performance of electrochemical energy storage technologies. Therefore, this paper summarizes the present or potential thermal hazard issues of lithium batteries (Li‐ion, Li–S, and Li–air batteries). Lithium‐ion batteries (Li‐ion batteries) are commercialized as power batteries in electric vehicles (EVs) because of their advantages (such as high energy density, long life span, etc.), while for future electrochemical energy storage markets, lithium–sulfur (Li–S) and lithium–air (Li–air) batteries can be promising candidates for high energy density requirements. In addition to the higher energy density requirements, safety is also an essential factor for developing electrochemical energy storage technologies. This work may provide an effective paradigm for the development of high-performance energy storage devices.Įlectrochemical energy storage is one of the critical technologies for energy storage, which is important for high‐efficiency utilization of renewable energy and reducing carbon emissions. Consequently, the lithium–air battery can work stably at 140 ☌ with a high specific current of 10 A g-1 for 380 cycles, indicating high stability and good rate performance at high temperatures. In addition, the high temperature has also largely improved the specific powers by increasing the ionic conductivity and catalytic activity of the cathode. Meanwhile, the fiber format can offer both flexibility and weavability, and realize rapid heat conduction and uniform heat distribution of the battery. The aligned carbon nanotubes have good electric and heat conductivity. Ionic liquids can offer wide electrochemical windows and low vapor pressures, as well as provide high thermal stability for lithium–air batteries. Herein, through the use of an ionic liquid and aligned carbon nanotubes, and a fiber shaped design, a new type of lithium–air battery that can effectively work at high temperatures up to 140 ☌ is developed. Therefore, a kind of lithium–air that can work stably under high temperature is desirable. In this case, serious safety problems may occur and cause great harm to people. However, organic solvents in electrolytes are likely to rapidly vaporize and form flammable gases under increasing temperatures. Driven by the increasing requirements for energy supply in both modern life and the automobile industry, the lithium–air battery serves as a promising candidate due to its high energy density.
