Overview
- The latest ec3 formulation stores over 2 kWh per cubic meter, cutting a typical home’s daily requirement to about 5 m3 from roughly 45 m3 in 2023.
- Focused ion beam–SEM tomography revealed a fractal-like nanocarbon web around pores that enables electrolyte infiltration and current flow.
- Performance rose after electrolytes were added directly to the mixing water and optimized with quaternary ammonium salts in acetonitrile, which allowed thicker electrodes.
- Researchers say viable electrolytes include seawater, pointing to potential use in coastal structures and offshore wind supports.
- Prototype demos included a 9 V ec3 arch that powered an LED and flickered under stress, as teams pursue applications like EV‑charging roads and off‑grid homes while the technology remains early‑stage.
