Wireless bipolar electrodes boost zinc-air battery power output by 80%

Spanish-Argentine researchers developed wireless bipolar electrodes that increase zinc-air battery power output by up to 80% while reducing internal resistance.

This advancement, published in *Energy Storage Materials* (August 2026), enables zinc-air batteries to achieve up to 80% higher power output using wireless bipolar electrodes. The electrodes reduce internal resistance without altering the core battery chemistry. Developed jointly by the Institute of Materials Science of Barcelona (ICMAB-CSIC), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), and the National University of La Plata (Argentina), the innovation addresses key limitations in grid-scale energy storage. The publication date (August 2026) is future-dated in the source, indicating it is a placeholder for the actual release. This work represents a technical step toward viable zinc-air batteries for grid storage, though the innovation remains in the research phase and has not yet been deployed at scale. The source provides no cost comparisons or deployment timelines for lithium-ion alternatives.
