Zinc Battery with 3D-Printed Electrode Unveiled
On June 30 at 19:45, researchers from UCLA announced a zinc battery featuring a 3D-printed electrode that merges the capabilities of a lithium-ion battery with those of a supercapacitor. This novel energy storage device leverages cutting-edge techniques, potentially reshaping the future of the field. The innovation addresses the growing demand for safer, more sustainable alternatives to traditional lithium-based systems.
The battery consists of two key components:
- One terminal operates as the storage element of a lithium-ion battery;
- The other terminal employs a carbon electrode similar to those found in supercapacitors.
The inventors enhanced the carbon electrode's surface area by infusing it with vanadium oxide, boosting its performance. The electrode was fabricated using 3D printing, where liquid resin solidifies under an ultraviolet laser. Remarkably, one gram of this material, if flattened, could cover roughly 10 tennis courts.
During testing, the zinc battery delivered impressive results: it retained 82% of its capacity after 1,500 charge-discharge cycles. The research team also introduced a 3D-printed test cell, offering a more affordable alternative to pre-made glass cells that cost upwards of $1,000.
The future of energy storage will not be defined by any single technology.

Sofia Uemura, the study's lead author, added: 'We hope this concept will prove useful to other researchers in the field, helping them achieve more stable measurements and reliable data for their devices.'
The findings were published in the journal Small. This invention could represent a major step forward in energy storage technology, combining the strengths of different battery systems.
Outlook for Energy Storage Technology
The development of the zinc battery with a 3D-printed electrode at UCLA reflects an active search for new energy storage solutions, a critical element in the shift toward renewable energy sources. Greater accessibility to technologies like 3D printing may help lower costs and simplify the production of new energy systems. This opens up fresh opportunities for research and commercial adoption, potentially benefiting both the environmental and economic aspects of the energy sector.
In addition to this groundbreaking zinc battery, researchers are exploring other innovative energy storage solutions. For instance, a recent study introduced a water-based battery that boasts an impressive runtime of 2,800 hours without failure. Such advancements highlight the diverse approaches being taken to enhance the efficiency and sustainability of battery technology.
