Scientists in Australia have developed a new type of battery that could potentially be fully charged in just three minutes while offering an exceptionally long lifespan.
Researchers at Flinders University developed the battery using a zinc-iodine technology that differs significantly from the lithium-ion batteries commonly used in smartphones today.
The researchers say the new battery can reportedly withstand around 60,000 complete charging cycles. If such performance could be achieved in everyday devices, it would represent a major improvement over current smartphone batteries, which generally experience noticeable degradation after a few years.
How the New Battery Works
Most modern smartphones rely on lithium-ion batteries. These batteries use materials such as lithium cobalt oxide and graphite to store and release electrical energy.
During charging and use, lithium ions move between the different layers of the battery. This process allows the battery to store energy and subsequently provide electricity to the device.
However, charging and discharging can generate heat, particularly when a device is being used heavily or charged rapidly. Repeated exposure to heat and charging cycles gradually reduces battery performance.
The Australian researchers have taken a different approach by using zinc and iodine.
Their system also incorporates a relatively inexpensive cyclodextrin-based polymer. Cyclodextrin is already used in a variety of industries, including food, cosmetics and pharmaceutical products.
According to the researchers, the polymer can help manage charged particles within the battery, contributing to its performance and stability.
Potentially Extremely Long Battery Life
One of the most striking claims surrounding the technology is its ability to withstand approximately 60,000 full charging cycles.
For comparison, a smartphone battery that could genuinely maintain its performance for tens of thousands of cycles would last dramatically longer than today’s conventional batteries.
However, converting the number of laboratory charging cycles into a specific number of years of real-world smartphone use is not straightforward. A figure such as 164 years should therefore be viewed as a theoretical calculation rather than a realistic prediction for an actual phone.
Safer Technology
Another potential advantage of the zinc-iodine design is safety.
Unlike conventional lithium-ion batteries, which can become a fire risk under certain conditions, the researchers say their zinc-iodine system is designed to be much less prone to catching fire.
This could make the technology attractive not only for smartphones but also for other applications where battery safety and rapid charging are important.
Not Ready for Smartphones Yet
Despite the promising results, the new battery is not currently available for smartphones.
The researchers say further development and optimization are required before the technology can be incorporated into consumer electronics.
If the three-minute charging capability and extremely high cycle life can eventually be reproduced at commercial scale, the technology could have significant implications for smartphones, electric vehicles and energy-storage systems.
For now, however, it remains a promising research development rather than a replacement for the lithium-ion batteries used in today’s smartphones.
