“…During the continuous phase transformation process from H1-monolithic(M)-H2-H3 during charging, the temperature rises from 24.9 °C to 26.7 °C due to the combined action of electrochemical reaction heat, Joule heat and polarization heat. [18] Turning to the discharge process, a gradually decrease temperature is detected during the H3-H2 phase transition, which is attributed to an endothermic process. [19] The weak temperature change during the H2-M phase transition is ascribed to the smaller heat production and heat exchange between the thermostatic test chamber and batteries.…”

High‐capacity Ni‐rich layered oxides are promising cathode materials for fabrication of lithium‐ion batteries (LIBs) with high energy density. However, thermal runaway of LIBs with these cathodes leads to great safety concerns. In this study, single crystalline LiNi0.9Co0.05Mn0.05O2 (NCM‐SC) has been prepared and a flexible optical fiber was buried inside the pouch‐type LIBs with NCM‐SC cathode to in‐situ study its real‐time temperature evolution during charge/discharge process. NCM‐SC exhibits an enhanced Li+ ions transportation efficiency and electrode reaction kinetics, which can effectively reduce the generation of polarization heat and mitigate the internal temperature rise of the pouch‐type battery. Meanwhile, solid‐electrolyte interface (SEI) film decomposition and gas accumulation are effectively alleviated, due to the enhanced thermal stability of SEI film formed on NCM‐SC. Moreover, the single crystal architecture can effectively retard layered to spinal and rock‐salt phase transition, mitigate the crack formation and structural collapse. Consequently, NCM‐SC exhibits an excellent electrochemical performance and enhanced thermal stability.

“…Fiber grating sensing technology offers many obvious advantages, such as high sensitivity, compact size, immunity to electromagnetic interference, ease of building sensing networks, and powerful multiplexing capability [1][2][3][4][5]. It has attracted considerable attention, especially for the measurement of parameters such as temperature [6], refractive index [7], strain [8], and pressure [9], thereby making fiber Bragg grating (FBG) an excellent sensing element with great potential for use in fields such as biochemical sensing [10,11] structural health monitoring [12,13], and gas/oil exploration [14,15]. Although the simple structure of the FBG sensor offers good linearity * Author to whom any correspondence should be addressed.…”

To solve the cross-sensitivity problem affecting optical fiber sensors and realize multiparameter measurement, a microfiber Fabry–Perot interferometer (MFPI) is proposed and experimentally demonstrated. Simultaneous measurement of two distinct physical parameter (temperature and strain) is realized by monitoring wavelength and reflectivity of MFPI. In the temperature field range of 22-36 ℃, the maximum temperature sensitivity can reach 12 pm/℃. The maximum strain sensitivity is up to 0.8 pm/με in the strain range of 0-800 με. In the simultaneous measurement experiments, the relative errors of temperature and strain were 4.0 % and 0.8%, respectively. Furthermore, the sensing element used in this method was just a single fiber grating sensor without any coating layer, which demonstrated the significant advantage of the proposed method in reducing the complexity and cost of multiparameter measurement.

“…Regarding the research on the TR warning of batteries, the internal state of batteries can be directly measured using EIS and implanted internal sensors, but the cost of using this method is relatively high. [ 21,27–29 ] In this article, the pouch LiCoO 2 battery is taken as the research object, and the overcharge TR platform of LiCoO 2 battery is built. The changes of voltage and temperature in the process of overcharge TR were analyzed, the corresponding stages were divided, and the corresponding laws were summarized.…”

With the gradual popularization of new energy vehicles, fire accident reports are common. Overcharge is one of the main causes of an accident, which has the characteristics of sudden occurrence, no obvious signs, and difficulty in stopping the spread of fire. Therefore, herein, the law of safety change of pouch batteries after overcharging is studied and the expressions of the thermal runaway stage are derived based on the voltage, temperature, and temperature difference as the main parameters through thermal runaway experimental data, and then a three‐stage overcharge warning strategy based on multiple parameters is constructed to build a warning model. The early warning model can predict the overcharge stage of batteries and provide the remaining time before thermal runaway, which is implemented and verified.
