Abstract

Structural batteries offer a novel solution to the issue of battery mass as a “weight burden” and can also alleviate the problem of “range anxiety” in electric vehicles (EVs). This paper reviews structural battery design methods. By comparing the advantages of decoupled structural battery design and coupled structural battery design in relation to vehicle structural characteristics, it is found that vehicles incorporating decoupled structural battery designs may reach the market faster than those with coupled designs. The impact of structural battery applications on improving vehicle range is analyzed using the vehicle energy equation, along with an exploration of the boundary effects of increasing battery mass. Additionally, the paper discusses the challenges faced by structural batteries, particularly in real-world vehicle application scenarios. Finally, the paper discusses the potential applications of structural batteries in other fields and explores their potential in low-altitude aerial vehicles. Through a review and discussion of current research in the field of structural batteries, the goal is to encourage more scholars to focus on this technology and to promote its application not only in the vehicle industry but across a wider range of fields.

结构电池在汽车上应用的前景与挑战

结构电池为解决电池质量作为“重量负担”的问题提供了一种新颖的解决方案，也可以缓解电动汽车的“里程焦虑”问题。本文综述了结构电池的设计方法。通过比较解耦结构电池设计与耦合结构电池设计在整车结构特性方面的优势，发现采用解耦结构电池设计的汽车比采用耦合结构电池设计的汽车更快进入市场。利用车辆能量方程分析了结构电池的应用对提高车辆续航里程的影响，并探讨了增加电池质量的边界效应。此外，本文还讨论了结构电池面临的挑战，特别是在实际车辆应用场景中。最后，讨论了结构电池在其他领域的潜在应用，并探讨了其在低空飞行器上的应用潜力。通过对结构电池领域研究现状的回顾和讨论，目的是鼓励更多的学者关注该技术，并推动其不仅在汽车行业，而且在更广泛的领域得到应用。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
