Coupled and decoupled structural batteries: A comparative analysis.

Amidst growing concerns over global warming and the urgent need for viable solutions, electric vehicles (EVs) have emerged as a promising remedy. However, the full transition to EVs faces certain challenges, necessitating more efficient electric storage systems. In this context, structural batteries have garnered significant interest as a multifunctional solution. This paper presents a comprehensive review of the latest advancements in structural batteries, exploring their distinctive characteristics and their potential to enhance EVs' performance. Particularly, a comparative analysis will be conducted based on the chosen chemistry for the electrochemical component and the reinforcement materials used. Additionally, crucial aspects such as recycling and life cycle analysis will be briefly discussed. Through this examination, it is intended to shed light on the potential of structural batteries in driving a sustainable and efficient EV ecosystem.
