3D Printed Battery Electrolyte Breakthrough by UTEP (2026)

July 6, 2026 — In a significant advancement in energy storage, researchers at The University of Texas at El Paso (UTEP) have unveiled a method to 3D-print battery components in nearly any shape. This 3D-printed battery electrolyte breakthrough could fundamentally change how engineers design portable electronics, medical implants, and aerospace systems.

Led by Alexis Maurel, Ph.D., the team created printable gel polymer electrolytes that perform on par with traditional options while offering unprecedented design freedom. Published on June 30, 2026, in Communications Engineering (a Nature journal), the study demonstrates how additive manufacturing can overcome the rigid limitations of conventional batteries.

By enabling energy storage to be integrated directly into devices rather than forcing devices to accommodate bulky cells, this development addresses a long-standing constraint in product design. The implications extend across consumer electronics, healthcare, and defense applications.

What Is the UTEP 3D-Printed Battery Breakthrough?

The innovation centers on gel polymer electrolytes, the crucial internal component that transports lithium ions between a battery’s electrodes. Unlike liquid electrolytes that require rigid, leak-prone casings, these gels can be solidified into custom forms.

The UTEP team’s work, detailed in the peer-reviewed study, focuses on creating stable, high-conductivity materials suitable for real-world lithium-based batteries. This represents a key step forward in gel polymer electrolyte 3D printing technology, moving beyond theoretical concepts to practical, printable formulations.

How Does the 3D Printing Process Work?

The process utilizes vat photopolymerization, a precise light-based 3D printing technique. Researchers combined a light-curable resin with a lithium-based liquid electrolyte, then cured the mixture layer by layer using targeted light exposure.

A key finding was the optimal one-to-four ratio of resin to electrolyte. This formulation delivers strong electrochemical performance while ensuring reliable print quality. Notably, the team achieved successful prints in ordinary laboratory air, eliminating the need for expensive, sealed, oxygen-free chambers, a major practical advantage over many previous attempts at vat photopolymerization of battery components.

This ambient-condition printing makes the technology more scalable and accessible for broader adoption in research and industry settings.

Performance Results and Advantages

The printed electrolytes demonstrated excellent performance metrics. They reached ionic conductivities of up to 3.4 × 10⁻³ siemens per centimeter, closely matching conventional liquid electrolytes they aim to replace.

Key advantages include:

• Design freedom: Batteries no longer dictate device shape.
• Safety improvements: Reduced risk of leaks from rigid liquid casings.
• Manufacturing simplicity: Effective printing in standard conditions.

To illustrate potential, the researchers produced simple discs, an open honeycomb lattice structure, and a solid one-centimeter cube. These examples highlight how custom-shaped batteries could conform to irregular spaces in future products.

Why This Matters – Future Applications

“For years, the shape of a battery has dictated the shape of the device it powers,” said Alexis Maurel, Ph.D., the study’s lead researcher and a faculty member in UTEP’s Department of Metallurgical, Materials and Biomedical Engineering. “We are showing that you can print a high-performing electrolyte battery component with any shape and place it almost anywhere you want. That changes what designers are able to imagine.”

This flexibility opens doors for 3D-printed batteries in 2026 and beyond in numerous sectors:

• Wearables and consumer electronics: Ultra-thin or curved power sources for smartwatches and AR glasses.
• Medical devices: Custom implants and portable health monitors.
• Aerospace and drones: Lightweight, space-optimized energy storage.
• Electric vehicles and beyond: Potential for structural batteries that integrate into chassis.

“This research demonstrates how advanced manufacturing and energy technologies are merging to create entirely new possibilities for battery design,” said Kenith Meissner, Ph.D., dean of the Miguel A. Loya College of Engineering. “By developing a scalable method to 3D-print battery electrolytes in virtually any shape, Dr. Maurel and his collaborators are helping position UTEP at the forefront of next-generation energy storage research while providing our students with hands-on experience in technologies that are critical to the future of aerospace, transportation, and advanced manufacturing.”

Collaboration and Next Steps

The project involved collaboration with Sandia National Laboratories, combining academic innovation with national lab expertise. The team plans to refine formulations further and integrate the printed electrolytes into complete battery cells.

This work also supports workforce development. It forms part of Maurel’s portfolio backed by a National Science Foundation Research Experiences for Undergraduates grant, creating paid summer internships in partnership with Texas A&M University.

Broader Impact on 3D Printed Battery Technology

The UTEP achievement arrives amid growing interest in additive manufacturing for energy storage. Across the industry, researchers and companies are exploring 3D printing to enhance battery density, reduce waste, and enable novel architectures that traditional methods cannot achieve.

By addressing solvent selection and printability challenges, areas previously underexamined, the study provides valuable guidance for future gel polymer electrolyte 3D printing efforts. It contributes to a shift toward more adaptable, safer, and application-specific batteries.

While challenges remain in scaling production and long-term cycle life, this research marks meaningful progress toward the commercial viability of custom-shaped batteries.

Conclusion

UTEP’s 3D-printed battery electrolyte breakthrough signals a promising evolution in how power sources can be designed and deployed. By combining high performance with geometric freedom, it challenges the constraints that have shaped battery-powered devices for decades.

As the field of 3D-printed batteries advances, innovations like this will likely influence everything from everyday gadgets to critical infrastructure. The ability to print functional electrolytes in ambient conditions brings practical manufacturing closer to reality.
