1.1 The Concept of Structural Batteries

Structural batteries are a novel concept that combines energy storage and structural function into a single unit. Unlike traditional batteries that simply add weight to a vehicle or device, structural batteries contribute to the overall strength and stiffness of the structure. This dual functionality can lead to significant weight reductions, making vehicles and devices more energy-efficient. [1]

The significance of structural batteries extends beyond just weight reduction. By integrating the battery into the structure of the vehicle or device, designers can free up space, allowing for more innovative and flexible designs. This has far-reaching implications for the future of electric vehicles and devices, potentially revolutionizing the way they're designed and manufactured.

1.2 The Role of AFP Technology in Composites Manufacturing [2]

AFP technology is a cutting-edge manufacturing technique used in the production of composite materials. It involves the precise placement of carbon, glass, or other types of fibers onto a mold using a computer-controlled system. This allows for the creation of complex shapes and structures that would be difficult, if not impossible, to achieve with traditional manufacturing methods.

In the context of structural battery manufacturing, AFP technology can play a crucial role. It can be used to precisely place the carbon fibers used in the negative electrode of the battery, ensuring optimal performance. Furthermore, AFP technology can automate the layering process involved in the manufacturing of structural batteries, enhancing accuracy and consistency.

2. Understanding Structural Batteries

In the realm of electric vehicles and devices, the concept of structural batteries is gaining significant traction. These batteries are not just energy storage systems; they are integral parts of the structure of the device or vehicle, contributing to its overall strength and stiffness. This section delves into the manufacturing process of structural batteries, based on the research paper "A Structural Battery and its Multifunctional Performance".

2.1 The Manufacturing Process of Structural Batteries

The manufacturing process of a structural battery is a fascinating blend of materials science and engineering. Here's a step-by-step breakdown:

• Carbon Fiber Negative Electrode: The process begins with the creation of a negative electrode made from carbon fiber (CF). The CF serves a dual purpose: it adds stiffness and strength to the battery, and it also acts as a current collector.
• Structural Electrolyte: Next, a structural electrolyte is introduced. This electrolyte is responsible for both load transfer and ion transport. It's a key component that allows the battery to function as a structural element.
• Glass Fiber Fabric Separator: A glass fiber fabric is used to separate the CF negative electrode from the positive electrode. This separator is crucial for maintaining the integrity of the battery and preventing short circuits.
• Aluminum Foil-Supported Positive Electrode: The final step in the process is the addition of an aluminum foil-supported lithium–iron–phosphate positive electrode. This electrode is responsible for the electrochemical reactions that generate electricity.

2.2 Multifunctional Constituents in Structural Battery Manufacturing

The manufacturing process of structural batteries is unique in that it employs multifunctional constituents. Each component serves multiple functions, contributing to both the structural integrity and the electrical performance of the battery. Here's a closer look at these constituents: [3]

• Carbon Fibers (CFs): CFs are used as the negative electrode in the battery. They not only add stiffness and strength to the battery but also act as a current collector. This dual functionality makes CFs a critical component in structural batteries.
• Structural Electrolyte: The structural electrolyte in the battery serves two main functions: load transfer and ion transport. This allows the battery to function as a structural element while also facilitating the necessary electrochemical reactions.
• Glass Fiber Fabric: The glass fiber fabric serves as a separator between the negative and positive electrodes. This prevents short circuits and maintains the structural integrity of the battery.
• Aluminum Foil-Supported Positive Electrode: The positive electrode in the battery is supported by an aluminum foil. This electrode is responsible for the electrochemical reactions that generate electricity, while aluminum foil provides structural support.

3. The Role of AFP in Structural Battery Manufacturing

AFP technology is revolutionizing the way we manufacture composite materials, and its application in the production of structural batteries is no exception. This section explores how AFP technology can be integrated into the manufacturing process of structural batteries and the unique benefits it brings. [4]

3.1 Integrating AFP Technology in Structural Battery Manufacturing

AFP technology can be a game-changer in the manufacturing process of structural batteries. Here's how:

1. Precision Placement of Fibers: AFP technology allows for the precise placement of fibers, which is crucial in creating the carbon fiber negative electrode in structural batteries. This precision ensures optimal performance of the electrode and, by extension, the battery.
2. The Layering of Components: The manufacturing process of structural batteries involves layering different components, including the carbon fiber negative electrode, the structural electrolyte, the glass fiber fabric separator, and the aluminum foil-supported positive electrode. AFP technology can automate this layering process, ensuring accuracy and consistency.
3. Scalability: AFP technology can significantly speed up the manufacturing process, making it easier to scale up production. This is particularly important as the demand for structural batteries is expected to grow in the coming years.

3.2 Unique Characteristics and Benefits of AFP Systems

AFP systems like AFP-XS, AFP-X, and SCF3D each bring unique characteristics and benefits to the table. Let's take a closer look:

• AFP-XS: This introductory and modular single-tow AFP system is ideal for experimentation with different widths and types of materials. Its versatility and modularity make it suitable for a wide variety of applications, including the production of structural batteries.
• AFP-X: This production-class multi-tow AFP system is designed for achieving a higher production rate for complex parts. It can carry up to 4x more materials than the AFP-XS, making it a great choice for the large-scale production of structural batteries.
• SCF3D: This system is Addcomposites’ response to the increasing demand for continuous fiber additive manufacturing. It incorporates continuous fibers throughout the printing process, eliminating the need for additional reinforcement steps. This system can deliver high-quality, structural components, making it ideal for the production of structural batteries.
