“…In the discharge process of lithium iron phosphate battery, the heat capacity unit volume is mainly composed of irreversible heat and reversible heat of which irreversible heat dominates, and this paper does not consider the reversible heat for simplicity. Where the irreversible heat production per unit volume can be calculated by eq Q b = I V ( false( U − U 0 false) + T normald U 0 normald T ) = I V ( I R r + T normald U 0 normald T ) where Q b is the rate of heat capacity unit volume inside the battery, V is the total volume of battery, I is the charging and discharging current of battery, charging is positive, discharging is negative, U is the open circuit voltage, U 0 is the operating voltage, T is the initial temperature of battery, R r is the equivalent internal resistance of battery, normald U 0 normald T is the temperature effect coefficient, which varies with the battery operating voltage, I 2 R r denotes the Joule heat and polarization heat components, and T normald U 0 normald T denotes the reaction heat component, but in practical calculations, this heat is a small percentage of the total heat generation, so it can be simplified and ignored.…”

In recognition of their excellent capacity for regulating thermal energy storage and release, phase change materials (PCMs) have been rediscovered and received growing significance in advanced solar energy storage and battery thermal management (BTM). Nevertheless, their insufficient thermal conductivity, poor shape stabilization, and high rigidity hinder their application in BTM systems. Herein, we reported a novel stable ordinary temperature flexible phase change material (FPCM) basis of paraffin wax (PW), polyolefin elastomer (POE), and expanded graphite (EG), which efficiently solves the aforementioned problem. And then, through flexibility, the FPCM was smartly mounted on the power batteries by overfilling, making the components compact and efficient. Thermal contact resistance (TCR) while operating the battery pack could be decreased by the flexible wrapping of the FPCM. Results show that the above BTM assembly effectively reduced the TCR to 0.28 °C/W. This FPCM-based reactive cooling BTM ensures that the temperature of the battery pack is kept under a safe temperature (55 °C) at all times. With the effect of EG, the prepared FPCM exhibits a substantial improvement in thermal conductivity, achieving 1.929 W/mK, as well as a prominent photothermal efficiency of conversion (91.2%). Notably, its ultraflexibility, high thermal conductivity, and excellent latent heat provide a convenient way for the thermal management packaging of complex and multimodel electronic devices.

“…Mechanical vibration plays a crucial role in the PCM-based BTMS, helping to restrict excessive temperature elevation and enhance the uniformity of temperature in lithium-ion batteries. Zhou et al [75] examined the impact of mechanical vibration on a PCM-based module for thermal management in a single 26650 cylindrical cell, particularly under high ambient temperature and high discharge rate. Their findings indicated that mechanical vibration improved natural convection heat transfer, mitigating excessive temperature rise and promoting temperature uniformity.…”

This paper presents a comprehensive review of the thermal management strategies employed in cylindrical lithium-ion battery packs, with a focus on enhancing performance, safety, and lifespan. Effective thermal management is critical to retain battery cycle life and mitigate safety issues such as thermal runaway. This review covers four major thermal management techniques: air cooling, liquid cooling, phase-change materials (PCM), and hybrid methods. Air-cooling strategies are analyzed for their simplicity and cost-effectiveness, while liquid-cooling systems are explored for their superior heat dissipation capabilities. Phase-change materials, with their latent heat absorption and release properties, are evaluated as potential passive cooling solutions. Additionally, hybrid methods, such as combining two or more strategies, are discussed for their synergistic effects in achieving optimal thermal management. Each strategy is assessed in terms of its thermal performance, energy efficiency, cost implications, and applicability to cylindrical lithium-ion battery packs. The paper provides valuable insights into the strengths and limitations of each technique, offering a comprehensive guide for researchers, engineers, and policymakers in the field of energy storage. The findings contribute to the ongoing efforts to develop efficient and sustainable thermal management solutions for cylindrical lithium-ion battery packs in various applications.

The burgeoning electric vehicle industry has become a crucial player in tackling environmental pollution and addressing oil scarcity. As these vehicles continue to advance, effective thermal management systems are essential to ensure battery safety, optimize energy utilization, and prolong vehicle lifespan. This paper presents an exhaustive review of diverse thermal management approaches at both the component and system levels, focusing on electric vehicle air conditioning systems, battery thermal management systems, and motor thermal management systems. In each subsystem, an advanced heat transfer process with phase change is recommended to dissipate the heat or directly cool the target. Moreover, the review suggested that a comprehensive integration of AC systems, battery thermal management systems, and motor thermal management systems is inevitable and is expected to maximize energy utilization efficiency. The challenges and limitations of existing thermal management systems, including system integration, control algorithms, performance balance, and cost estimation, are discussed, along with potential avenues for future research. This paper is expected to serve as a valuable reference for forthcoming research.
