Description
Zhiyuan Zha leads a 2026 materials study on a composite electrode for aqueous, water-based, dual-ion batteries. Such batteries are safe and eco-friendly but suffer slow ion movement and structural swelling as ions enter and leave. The team combined bismuth telluride with antimony phosphate on nitrogen-doped carbon frameworks to form a heterointerface, a junction between unlike materials.
The junction creates a built-in electric field that speeds charge transport, while the carbon frame spreads material evenly and cushions swelling. Computer calculations showed stronger binding for both zinc and ammonium ions than the base material alone. Devices stored high charge for both ions and kept nearly full capacity over thousands of cycles for zinc, guiding dual-ion battery design.
