Due to their exceptional properties and diverse applications, including to magnetic devices, thermoelectric materials, catalysis, biomedicine, and energy storage, nanoscale metallic multilayer composites (NMMCs) have recently attracted great attention. The alternating layers of two or more metals that make up NMMCs are each just a few nanometers thick. The difficulties in producing and synthesizing new materials can be overcome by using nanoscale multilayer architectures. By adjusting the layer thickness, composition, and interface structure, the mechanical properties of these materials can be controlled. In addition, NMMCs exhibit unusually high strength at thin layer thicknesses because the multilayers have exceptionally high strength, as the individual layer thicknesses are reduced to the nanoscale. The properties of NMMCs depend on the individual layers. This means that the properties can be tuned by varying the layer thickness, composition, and interface structure. Therefore, this review article aims to provide a comprehensive overview of the mechanical properties and the application of high-performance NMMCs. The paper briefly discusses the fabrication methods used to produce these composites and highlights their potential in various fields, such as electronics, energy storage, aerospace, and biomedical engineering. Furthermore, the electrical conductivity, mechanical properties, and thermal stability of the above composite materials are analyzed in detail. The review concludes with a discussion of the future prospects and challenges associated with the development of NMMCs.

“…Nevertheless, the main challenges of liquid cooling include its complex structure, high energy consumption and the risk of coolant leakage [11]. Compared to active thermal management methods, PCM cooling is more cost-effective and provides good temperature uniformity [14][15][16]. However, the primary drawbacks of PCM are low thermal conductivity and volume expansion, and it is ineffective when the melting point temperature of the PCM does not match the operating temperature of the battery [17].…”

The air-cooled battery thermal management system (BTMS) is a safe and cost-effective system to control the operating temperature of battery energy storage systems (BESSs) within a desirable range. Different from the design of the air supply flow field of most BESSs in previous studies, this study proposes a novel combined the cooling air duct and the battery pack calculation method to enhance the heat dissipation of the battery. Using computational fluid dynamics (CFD) models, potential problems with numerical calculations of cooling air duct and battery packs alone and coupled simulations of the two are investigated. The important factor influencing the uniformity of air supply is identified, and creative measures for improvement are proposed. The results in this paper indicate that the uniformity of the outlet air supply does not indicate that the temperature uniformity performance of the matrix battery meets the requirements due to the variation of the sub air duct outlet pressure, and the coupling simulation of the cooling air duct and the battery pack is an essential process for BESSs. With the improvements proposed in this paper, the standard deviation coefficient of velocity is reduced from 60.3% to 12.6%. Furthermore, the innovative improvement of placing the partition at the connecting duct can regulates the battery temperature between 298.58 K and 311.73 K and ensures a maximum temperature difference of only 4.22 K for a single battery. Ultimately, the power consumption of the cooling system can be reduced by 6.9%. The results of the paper provide a guide for uniform heat dissipation in BESSs.

The battery thermal management system (BTMS) utilizing phase change materials (PCM) has shown promising performance in high heat flux heat dissipation. However, conventional PCM systems do not fully exploit the latent thermal properties of paraffin wax to enhance battery cooling efficiency. To address this issue, this paper proposes a novel multilayer composite material for BTMS, aiming to improve the thermal performance of the battery and overcome the low thermal conductivity of paraffin wax. The preparation process involves positioning the battery at the center of a triangular container, melting paraffin wax and pouring it into a 100 mm high container to form a 20 mm paraffin layer, placing copper foils and graphite layers on the paraffin surface, and repeating this step once. Finally, pour the 40 mm paraffin wax into the container, resulting in a sandwich-like structure with two layers of graphite. The cooling performance of the multilayer composite structure was experimentally tested at different ambient temperatures (15°C and 20°C) and discharge rates, and compared with a conventional BTMS based on pure paraffin wax. The results demonstrate that the multilayer composite structure exhibits superior heat dissipation compared to the pure paraffin structure, significantly reducing battery temperature rise, particularly at higher discharge rates. At an ambient temperature of 20°C and a discharge rate of 5°C, the battery temperature rise is only 14.97°C, with a remarkable cooling effect of 32.6%. Moreover, optimization of the number and thickness of graphite layers in the composite structure reveals that the 6-layer graphite structure outperforms the 2-layer, 4-layer, 8-layer, and 10-layer graphite structures. Additionally, a relatively lower battery surface temperature is observed with a graphite thickness of 0.5 mm on the basis of the 6-layer graphite structure. These findings indicate that the proposed novel layout structure exhibits excellent thermal performance, effectively addressing the low thermal conductivity limitation of traditional paraffin cooling systems, and providing a new approach for thermal management of lithium batteries.
