“…where B is the factor of thermal sensitivity, R is the resistance, k B is the Boltzmann constant, and T is the absolute temperature. Note that the B value defines the relationship between the thermistor's resistance and temperature, which represents the material constant over a specific temperature interval (e.g., between T 1 and T 2 ) [27,28]. Also, a relationship between the resistance and temperature of the (Ni 0.6 Co 0.4 Mn 2 )O 4 pellet can be utilized for temperature sensing applications.…”

This study demonstrates the current advancements in battery management systems (BMSs), emphasizing the need for precise temperature monitoring within battery packs to enhance safety and performance through efficient thermal management. The increased demand for lithium-ion batteries (LIBs) has driven the development of temperature sensors with improved accuracy and stability. In particular, Ni-Co-Mn-based spinel oxides are commonly used due to their stable negative temperature coefficient (NTC) behavior. However, challenges arise in manufacturing due to the high cost and uncertain supply of critical cathode components (e.g., Co, Ni, and Mn) for LIBs. This research focuses on developing spinel-type (Ni0.6Co0.4Mn2)O4 using recycled Ni-Co-Mn oxides obtained from end-of-life (EOL) LIBs, demonstrating temperature resistance behavior suitable for temperature sensing. The oxides are prepared through hydrometallurgy, oxalate synthesis, and post-heat treatment. Successful integration into spinel-type NTC thermistors suggests broader applications in various industrial fields. A systematic investigation into the synthesis and characterization of recovered Ni-Co-Mn oxides from EOL LIB cathode materials (Li(Ni0.33Co0.33Mn0.33)O2) is presented for NTC thermistor application. Thermogravimetric analysis-derivative thermogravimetry (TGA-DTG) identifies the optimal post-heat treatment temperature. The X-ray diffraction (XRD) patterns confirm a cubic spinel structure of the Ni-Co-Mn oxides, supported by scanning electron microscope (SEM) images showing a uniform microstructure. Also, energy dispersive X-ray spectroscopy (EDS) mapping confirms homogeneous element distribution. Recovered oxide pellets from the sintering process exhibit a single spinel structure, with X-ray photoelectron spectroscopy (XPS) analysis revealing changes in the valence states for Ni and Mn. Resistivity measurements demonstrate semiconductive behavior, which shows a B value (3376.92 K) suitable for NTC thermistor applications. This study contributes valuable insights to black powder recycling from EOL LIBs and its potential in temperature-sensitive electronic devices.

With rapid advancements in technology in the electronics sector, demand for the miniaturization of devices while retaining their functionality is on the rise. Metal oxidebased thermal sensors are desired, owing to their enhanced sensing capabilities and low cost of operation. Highly sensitive metal oxide sensors can enable stable, accurate, and miniaturized thermal sensors tailored to different operational ranges. However, the influence of humidity and how it affects the sensitivity of the material by interacting with the material surface has not been extensively studied. In this work, we report a vanadium dioxide (VO 2 )-based thin film thermal sensor studied under the influence of varying humidity conditions. The effect of different humidity levels on the overall thermal sensing behavior and the insulator-to-metal transition (IMT) phenomenon was investigated. Further, density functional theory (DFT) studies were conducted to understand the thermal sensing mechanism under changing humidity conditions. The developed sensor exhibited a good response over a broad temperature range of −100 to 100 °C, with a TCR of −0.00243%, high sensitivity, and cyclic repeatability. Wireless measurement capabilities were also demonstrated. Such sensors could potentially be used in environmental sensing applications.
