<p>➀ Researchers at TUM have developed a covalent organic framework (COF) material called 'TpBD-2F' to prevent dendrite formation and anode corrosion in zinc-ion batteries.</p><p>➁ The COF self-assembles on the surface of metallic zinc, creating a thin, porous layer that allows zinc ions to plate evenly while blocking water access.</p><p>➂ This breakthrough could enable zinc-ion batteries to replace lithium-ion batteries in large-scale energy storage applications, such as those paired with solar or wind power plants.</p>
