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.
With the rate of adoption of new energy vehicles, the manufacturing industry of power batteries is swiftly entering a rapid development trajectory. The current construction of new energy vehicles encompasses a variety of different types of batteries.
Working principle: When the battery is sufficient, the power battery drives the motor to provide the driving power of the whole vehicle. At this time, the engine is not working.
Battery technology in EVs When discharged, a battery produces electrical energy by converting chemical energy, and when charged, it converts electrical energy back into chemical energy. Batteries are composed of electrochemical cells placed in a parallel–series configuration.
To implement structural batteries in systems such as vehicles, several key points must be satisfied first, including mechanical and electrochemical performance, safety, and costs, as summarized in Fig. 8. In this section, these points will be briefly discussed, covering current challenges and future development directions. Figure 8.
