The automotive industry is transitioning toward electric vehicles (EVs) to control fossil fuel dependence, reduce CO2 emissions, and mitigate pollution. EVs powered by lithium‐ion batteries (LIBs) have gained significant popularity due to their low operational costs and high energy density. Despite the substantial popularity of EVs powered by LIBs, their widespread commercial deployment has been impeded by challenges associated with operating temperatures. These temperature variations can adversely affect battery performance, degradation, and safety, posing hurdles to overcome for their efficient integration into vehicles. To address these issues, the development of high‐performance effective cooling techniques is crucial in mitigating the adverse effects of surface temperatures on battery cells. This review article aims to provide a comprehensive analysis of the advancements and enhancements in battery cooling techniques and their impact on EVs. It explores various cooling and heating methods to improve the performance and lifespan of EV batteries. It delves into suitable cooling methods as effective strategies for managing high surface temperatures and enhancing thermal efficiency. The study encompasses a comprehensive analysis of different cooling system designs with innovative approaches. Furthermore, this article outlines future research directions and potential solutions for developing battery cooling systems in electric and hybrid electric vehicles.

Lithium‐sulfur batteries offer high energy density but face great safety and cycle life challenges due to the use of Li metal anode. Replacing the Li metal anode with pre‐lithiated carbon anodes can thoroughly address cycling stability and safety issues. Directly contacting Li foil with graphite electrode is one of the most efficient and simple strategy to introduce a high content of lithium source into the sulfur‐carbon full batteries. However, the 100% lithiation of the graphite anode through the direct contact method generates excessive heat and stress heterogeneity, which leads to electrode structure cracking and electrochemical properties fading. This study implements a double‐layer anode to mitigate these issues. A thin layer of hard carbon placed between graphite and Cu foil limits heat generation and stress heterogeneity due to its structural and electrochemical stability. Additionally, differing from traditional electrochemical lithiation, this method gains better solid electrolyte interphase (SEI) for the graphite anode after several cycles. This research highlights the mass production potential of coupling high energy density lithium source‐free cathode materials with various lithium source‐free anodes for constructing long‐cycle and high‐safety rechargeable batteries.

The primary purpose of this research is to analyze and evaluate the effects of various discharge rates and cell configurations on the electrochemical and thermal behavior of a Li‐ion battery pack that is exposed to ambient air throughout the discharge process. The three‐dimensional numerical model is designed to accomplish this purpose and discusses two different cases. While the discharge rate is changed from 0.5 C to 2 C (stepping by 0.5 C) for each cell configuration considered in the first case, the numerical solutions are obtained for the various cell configurations (6S4P and 8S3P) by keeping the discharge rate constant at 1 C. The results obtained from these solutions show that the discharge rate affects a considerable amount of the battery performances and discharge times of the battery packs, activation, and ohmic losses occurring inside each battery cell. Moreover, 6S4P discharges over a longer period (about 25%) than 8S3P. While both activation and ohmic losses decrease with the increase of discharge rate, these losses remain almost constant at 0.5 C discharge rate in all analyzed conditions. As a result, having a battery pack with a long discharge time while maintaining low temperatures is useful and desired. With this in mind, while evaluating battery packs, the 6S4P battery pack looks to have the best arrangement.
