  "textContent": "Scientists at HKUST have unveiled a major leap forward in calcium-ion battery technology, potentially opening the door to safer, more sustainable energy storage for everything from renewable power grids to electric vehicles. By designing a novel quasi-solid-state electrolyte made from redox-active covalent organic frameworks, the team solved long-standing issues that have held calcium batteries back—namely poor ion transport and limited stability.",
