A team at Australia's Flinders University has unveiled an aqueous zinc-iodine battery that can be fully recharged in just three minutes and retains its capacity through more than 60,000 charge-discharge cycles. The researchers position the device as a safer alternative to lithium-ion batteries, which are often criticized for their higher cost, flammability, and toxic waste.

To prevent leakage of iodine compounds, the engineers turned to starch-derived molecular traps. They built a polymer from cyclodextrin, a substance commonly used in food processing, which forms microscopic cages that hold reactive materials in place and stop the damaging leaks.

Project leader Zhongfan Jia said: 'This approach makes it possible to fight battery degradation using cheap, biodegradable components.'

The result could be a major step toward safer energy storage technologies.

Because the battery combines safety, speed, and durability, it has the potential to reduce reliance on lithium-ion systems and reshape the energy storage market. Demand for clean, non-toxic alternatives is growing rapidly, making this a promising area for further innovation in the fight against carbon emissions and the global shift to renewable energy. Advances like this are being closely watched as industries look for practical and sustainable storage options.

As the demand for innovative energy solutions increases, developments in battery technology are becoming more significant. For instance, a recent breakthrough in China has led to the creation of a lithium-metal cell that maintains performance even at -40°C. This advancement highlights the ongoing efforts to enhance battery efficiency and reliability in extreme conditions, complementing the momentum behind new alternatives like the aqueous zinc-iodine battery.
