“…Battery management system (BMS) has made significant progress for enhancing the operation of batteries. [37] Regardless of the development of battery technology, LiBs performance still depends on its temperature-driven reactions [38] and unpredictable dynamics. [39] According to the properties of the temperature coefficient and piezoresistive characteristics, Ag-CB-PDMS can be fabricated into two types of low-cost sensors: the Ag-CB-PDMS temperature sensor (sample 6, 2.39 RMB g À1 ) and the Ag-CB-PDMS pressure sensor (sample 4, 1.70 RMB g À1 ).…”

Flexible conductive polymer composites (CPCs) are creating new opportunities in soft electronics and their applications. Compared with CPCs based on unary filler systems, CPCs with binary fillers have plenty of advantages in mechanical and electrical properties due to the synergistic superiority of fillers. Herein, a new kind of flexible binary fillers CPC composed of nano-sized carbon black (CB) particles and micro-sized silver (Ag) platelets uniformly dispersed in polydimethylsiloxane (PDMS) is reported and named Ag-CB-PDMS. A synergistic conductive network structure based on observation of scanning electron microscope (SEM) is proposed. The conductivity is approximately 20 times higher than that of unary filler system, with a threefold improvement in its stability. Through the regulation of the filler concentration, the temperature coefficient can be adjusted, and the resistance is insensitive to temperature when silver and carbon black concentrations are 15 and 18 wt%, respectively. Meanwhile, Ag-CB-PDMS retains good flexibility and shows excellent piezoresistive characteristics. During compressionrelease cycles, Ag-CB-PDMS exhibits excellent stability, good repeatability (1000 cycles), and fast response time (52 ms). A temperature-pressure sensor is constructed based on Wheatstone bridge for real-time monitoring of lithium-ion batteries (LiBs) to achieve early safety warning.

“…Another reason is the existence of thermal delay between the internal temperature to the surface temperature caused by the very low thermal conductivity of the separator and electrodes 49 . In a recent study on the evolution of temperature within a Li‐ion battery during short circuit, it was found that there is a significant temperature gradient in both thickness and height direction of the battery 50 . Besides, the temperature rise within a Li‐ion battery during short circuit was found to occur asynchronously when analyzed with an infrared camera 51 .…”

Summary Safe and reliable operation is among the considerations when integrating lithium‐ion batteries as the energy storage system in microgrids. A lithium‐ion battery is very sensitive to temperature in which it is one of the critical factors affecting the performance and limiting the practical application of the battery. Furthermore, the adverse effects differ according to the temperature. The susceptibility of lithium‐ion battery to temperature imposes the need to deploy an efficient battery thermal management system to ensure the safe operation of the battery while at the same time maximizing its performance and life cycle. To design a good thermal management system, accurate temperature measurement is vital to assist the battery thermal management system in managing relevant states such as the stage‐of‐charge and state‐of‐health of the battery. This article outlines the effects of low and high temperatures on the performance of Li‐ion batteries. Next, a review of currently available internal temperature monitoring approaches is presented based on their feasibility and complexity. Then, an overview of battery thermal management systems based on different cooling mediums is presented. This includes air cooling, liquid cooling, phase change material (PCM) cooling, heat pipe cooling, boiling‐based cooling, and solid‐state cooling. The final section of this article discusses the practical implementation of the internal temperature measurement approach and battery thermal management system for microgrids. From the review, a suitable candidate is the flexible, low maintenance, and long lifetime hybrid battery thermal management system that combines heat pipe cooling and solid‐state cooling. It is capable of maintaining the maximum operating temperature of the battery within 45°C at up to 3C discharge rate while being a relatively simple system. Additionally, passive PCM with thermally conductive filler can also be employed to assist the hybrid battery thermal management system in improving the temperature uniformity well within 5°C.

Lithium‐ion batteries’ (LIBs) failure due to abusive cycling conditions can result in thermal runaway, which calls for reliable real‐time battery thermal safety monitoring. Herein, an effective method for LIB thermal runaway detection using a resistant temperature detector (RTD) is compared with a conventional battery surface temperature measurement. A direct electrode temperature measurement technique based on additive manufacturing‐enabled application of miniature RTDs for measurement of internal temperature within large‐capacity Li‐ion pouch cells is used. The miniature RTDs are embedded in a customized electrochemically inactive polymeric substrate for real‐time thermal safety monitoring during overcharge abuse. Electrode temperature profiles under different conditions of overcharge (at 1 and 5 C rate, charged until battery explosion) are analyzed and mechanisms of heat generation in LIBs during overcharge‐induced thermal runaway are investigated. The internal RTDs detect the onset temperature of the solid−electrolyte interface decomposition ≈10 s earlier than the sensors attached to the battery surface. A maximum temperature gradient of ≈200 °C is observed between the electrode and the battery surface during overcharge‐induced thermal runaway. The internal RTDs are shown as a possible guide for sensor placement location to capture the maximum temperature within the LIBs during abuse events.
