Researchers have developed innovative ‘water batteries’ that offer a safe, recyclable alternative to lithium-ion batteries for large-scale energy storage. These aqueous metal-ion batteries use water instead of flammable electrolytes, preventing fire hazards. Their sustainable design facilitates easy disassembly for material reuse or recycling. Significant advancements include overcoming dendrite growth, extending battery lifespan, and achieving competitive energy densities with potential applications in grid storage and renewable energy integration. The project’s success is underpinned by global collaboration and industry partnerships, signaling a promising direction for safer and more efficient energy storage solutions. (Artist’s concept).
