Special Issue Information

Dear Colleagues,

This issue aims to collect studies performed on thermoelectric materials and devices from different types of structures, including nanostructured materials and bulk materials. Since thermal treatment and high energy beam modify thermoelectric devices, causing quantum dot formation in the quantum layers, many remarkable results can be reached after those effects. Nanostructured systems may include but are not limited to single nanolayers, multilayer heterostructures, superlattice systems, etc. Different kinds of material systems may be selected from the periodic table for different purposes of applications at different temperatures and environmental conditions. Authors are invited to share their manuscripts prepared using different material systems and their results from different characterization techniques. Those techniques may include but are not limited to the Seebeck coefficient measurement, four probe van der Pauw resistivity systems, thermal conductivity measurements, different kinds of optical and electrical measurements systems such as SEM, TEM, FIB, XPS, Auger, NMR, Optical Absorption, FTIR, Raman, DSC, etc. At present, energy storage is also promising. Some studies including thin film solid state batteries with and without thermoelectric devices are also welcome to be submitted. Thermoelectric characterization techniques such as the Seebeck coefficient, electrical conductivity, and thermal conductivity measurement s could include in-plane and cross-plane measurements. Since the figure of merit, ZT, can be found using the Seebeck coefficient, electrical conductivity, and thermal conductivity measurement, in-plane ZT and cross-plane ZT results might be interesting in different application areas, from microlevel applications to electrical vehicle applications.

An efficient thermal management system (TMS) of electric vehicles requires a high-fidelity battery model. The model should be able to predict the electro-thermal behavior of the battery, considering the operating conditions throughout the battery’s lifespan. In addition, the model should be easy to handle for the online monitoring and control of the TMS. Equivalent circuit models (ECMs) are widely used because of their simplicity and suitable performance. In this paper, the electro-thermal behavior of a prismatic 50 Ah LMO/Graphite cell is investigated. A dynamic model is adopted to describe the battery voltage, current, and heat generation. The battery model parameters are identified for a single cell, considering their evolution versus the state of charge and temperature. The needed experimental data are issued from the measurements carried out, thanks to a special custom electrical bench able to impose a predefined current evolution or driving cycles, controllable by serial interface. The proposed battery parameters, functions of state of charge (SOC), and temperature (T) constitute a set of interesting and complete data, not available in the literature, and suitable for further investigations. The thermal behavior and the dynamic models are validated using the New European Driving Cycle (NEDC), with a large operating time, higher than 3 h. The measurement and model prediction exhibit a temperature difference less than 1.2 °C and a voltage deviation less than 3%, showing that the proposed model accurately predicts current, voltage, and temperature. The combined effects of temperature and SOC provides a more efficient modeling of the cell behavior. Nevertheless, the simplified model with only temperature dependency remains acceptable. Hence, the present modeling constitutes a confident prediction and a real step for an online control of the complete thermal management of electrical vehicles. Full article
