What are structural batteries?

This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.

What is a multifunctional lithium-ion battery?

A first milestone in the design and fabrication of multifunctional lithium-ion batteries was placed by Liu et al. , who realized carbon nanofibers structural batteries with tunable mechanical properties. The devices were realized with PVDF-based fiber reinforced composite with different fillers as the active material.

What can be done to improve the development of structural batteries?

The study of new interfacial treatments for both the batteries and the face sheets as well as the use of alternative solid-state batteries with enhanced mechanical properties and the increase in the operating temperature of the batteries may contribute positively to the development of the structural batteries of the future. 4.

Can structural composite batteries store electric energy and carry mechanical loads?

In this perspective, the idea of manufacturing structural composite batteries capable of storing electric energy and, at the same time, carrying mechanical loads is one of the most appealing applications of multifunctionality. Two main approaches have already been investigated.

What are lithium ion based batteries?

1. Introduction Lithium-ion based batteries have already demonstrated an unparalleled combination of high energy and power density, quick charge and long-life that made this technology the present choice for electric vehicles, portable electronic devices, and many other applications.

Are structural batteries multifunctional?

Owing to distinct material subsystems present in electrodes, electrolytes, and separators, the advancements in multifunctionality within structural batteries are explored separately. Striving to concurrently enhance mechanical properties and energy storage performance, several approaches have been reported.
