Integrating 3D printed graphene into energy storage devices boosts efficiency, enabling custom structures that enhance battery life and charge-discharge rates.
By Dr Silpaja Chandrasekar, PhDReviewed by Lexie CornerDec 20 2024 Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice.Graphene is known for its excellent electrical conductivity, mechanical strength, and thermal stability. Recent advancements have enabled the integration of graphene into 3D printing, allowing the creation of custom structures that combine graphene’s unique properties with the precision of additive manufacturing.
How is Graphene 3D Printed? Techniques like fused deposition modeling and stereolithography are commonly used to 3D print graphene-based materials. These methods are well-suited for creating complex shapes with high precision.2 A study published in Bioengineered highlighted that graphene-based electrodes, fabricated using advanced techniques, allow precise control over geometry and structure. This enables fine adjustments to properties like conductivity, surface area, and porosity.5
Hybrid Energy Systems Graphene-based batteries and supercapacitors can be combined to meet the demands of applications requiring both high energy density and rapid energy delivery. 3D printing enhances these systems by enabling tailored electrode designs, ensuring efficient energy retention and faster charge-discharge cycles. Customization also allows hybrid systems to balance storage capacity and power delivery while maintaining material efficiency and scalability.
Supercapacitors Supercapacitors benefit significantly from graphene’s ability to boost energy and power density while enabling rapid charge and discharge cycles. 3D-printed graphene structures further enhance surface area and porosity, which are critical for maximizing energy storage and delivery. The scalability of 3D printing supports the efficient production of customized designs for various applications, from portable devices to industrial systems.
As methods improve, these technologies may also play a role in renewable energy storage, helping manage supply fluctuations more effectively. While challenges remain, 3D-printed graphene has the potential to contribute to practical, efficient, and sustainable energy storage solutions. 4. Barreto, DN., et al. .
