“…More importantly, new configuration should meet the structural battery standard. [242] A backside metal Zn plating has been realized by introducing an insulating layer on the edges and front surface of Cu foil to face the Zn metal counter electrode, which can eliminate short circuits and enable the dendrites to grow away from the separator, avoiding the contact between the Zn metal and the separator. Additionally, the deformation strategy used to construct high-performance AZIBs by regulating Zn metal atomic structure through large rolling results in crystal orientation with exposing more (002) plane, exhibiting potential prospects in large-scale production.…”

Over the past decades, there has been a growing interest in rechargeable aqueous Zn‐ion batteries (AZIBs) as a viable substitute for lithium‐ion batteries. This is primarily due to their low cost, lower redox potential, and high safety. Nevertheless, the progress of Zn metal anodes has been impeded by various challenges, including the growth of dendrites, corrosion, and hydrogen evolution reaction during repeated cycles that result in low Coulombic efficiency and a short lifetime. Therefore, we represent recent advances in Zn metal anode protection for constructing high‐performance AZIBs. Besides, we show in‐depth analyses and supposed hypotheses on the working mechanism of these issues associated with mildly acidic aqueous electrolytes. Meanwhile, design principles and feasible strategies are proposed to suppress dendrites' formation of Zn batteries, including electrode design, electrolyte modification, and interface regulation, which are suitable for restraining corrosion and hydrogen evolution reaction. Finally, the current challenges and future trends are raised to pave the way for the commercialization of AZIBs. These design principles and potential strategies are applicable in other metal‐ion batteries, such as Li and K metal batteries.

Structural batteries have emerged as a promising alternative to address the limitations inherent in conventional battery technologies. They offer the potential to integrate energy storage functionalities into stationary constructions as well as mobile vehicles/planes. The development of multifunctional composites presents an effective avenue to realize the structural plus concept, thereby mitigating inert weight while enhancing energy storage performance beyond the material level, extending to cell‐ and system‐level attributes. Specifically, multifunctional composites within structural batteries can serve the dual roles of functional composite electrodes for charge storage and structural composites for mechanical load‐bearing. However, the implementation of these multifunctional composites faces a notable challenge in simultaneously realizing mechanical properties and energy storage performance due to the unstable interfaces. In this review, we first introduce recent research developments pertaining to electrodes, electrolytes, separators, and interface engineering, all tailored to structure plus composites for structure batteries. Then, we summarize the mechanical and electrochemical characterizations in this context. We also discuss the reinforced multifunctional composites for different structures and battery configurations and conclude with a perspective on future opportunities. The knowledge synthesized in this review contributes to the realization of efficient and durable energy storage systems seamlessly integrated into structural components.

Multifunctional materials offer a possibility to create lighter and more resource‐efficient products and thereby improve energy efficiency. Structural battery composites are one type of such a multifunctional material with potential to offer massless energy storage for electric vehicles and aircraft. Although such materials have been demonstrated, their performance level and consistency must be improved. Also, the cell dimensions need to be increased. Herein, a robust manufacturing procedure is developed and structural battery composite cells are repeatedly manufactured with double the multifunctional performance and size compared to state‐of‐the‐art structural battery cells. Furthermore, six structural battery cells are selected and laminated into a structural battery composite multicell demonstrator to showcase the technology. The multicell demonstrator performance is characterized for two different electrical configurations. The low variability in the multifunctional properties of the cells verifies the potential for upscaling offered by the proposed manufacture technique.
