The article Zink iodine batteries: Double-electrodes double performance first appeared at the online magazine Basic Thinking. You can start the day well every morning via our newsletter update.
A newly developed process with dry electrodes is intended to double the energy density of zinc -iodine batteries – and that with higher security and more charging cycles. Instead of liquid binders, a pure dry coating is used.
A battery that is not only safe, but also cheap, durable and can be made with wide -available materials: This is exactly what promises one New technology of the University of Adelaide. Because researchers have developed a zinc iodine battery that does not require expensive or combustible materials such as lithium or cobalt and should be more powerful.
The background: zinc is obtained from rock and iodine is in large quantities in sea water. Another advantage: The new battery uses water as a liquid inside and, in contrast to current technologies, is less flammable. This should make it safer and be easier to recycle.
Zinc iodine batteries with higher efficiency and longer lifespan
So far, many zinc iodine batteries failed on a relatively simple problem: researchers could not “pack” enough iodine in the batteries because it easily evaporated when manufacturing. Nevertheless succeeded, the iodine compounds hiked back and forth uncontrollably. This phenomenon is also known as a “shuttle effect” and robs performance.
The new solution: Instead of producing the electrode with liquid, the researchers designed them in a dry state. This protects the iodine, increases the amount inside and makes the battery more stable. At the same time, a thin protective layer on the zinc side forms in the company. This prevents dangerous metal needles from forming (so -called dendrites) that could otherwise destroy the battery.
Over 750 charging cycles – without large performance losses
The result: a zinc iodine battery that can store a lot of energy, can be charged over 750 times and loses hardly any performance-and that with low risk of fire and without major environmental problems. This would be a big step, especially in connection with solar and wind power plants.
The zinc iodine battery is therefore a powerful, practical solution for our energy future and could help store energy in an environmentally friendly and safe manner.

As a tech industry expert, I am excited about the potential of Zinc iodine batteries with dry electrodes to double performance. This innovation could significantly improve the energy storage capabilities of batteries, making them more efficient and reliable for various applications. The use of dry electrodes also eliminates the need for liquid electrolytes, which can be flammable and pose safety risks.
Furthermore, Zinc iodine batteries are known for their high energy density and long cycle life, making them a promising option for renewable energy storage and electric vehicles. By doubling their performance with dry electrodes, these batteries could become even more competitive in the market and help accelerate the transition to a clean energy future.
Overall, I believe that the development of Zinc iodine batteries with dry electrodes is a significant advancement in energy storage technology, and I look forward to seeing how this innovation will continue to evolve and make a positive impact on the industry.
