A new battery technology is about to hit the market with an exciting promise: to revolutionize the lifespan and performance of electric cars.
Developed by the American company Group1, the potassium-ion battery could outperform today's lithium-ion batteries in several important ways.

The Danish tech magazine Mobilsiden reports that these batteries can endure many more charge cycles without losing capacity, allowing electric car owners to enjoy their vehicle's full range even after years of use.
One of the most compelling benefits of potassium-ion batteries is the availability of potassium, which is abundant in the Earth's crust.
This contrasts with lithium, which is more scarce and expensive to mine.
The widespread availability of potassium could lead to lower production costs, which makes these advanced batteries more accessible to manufacturers and consumers alike.
In addition to their durability and cost-effectiveness, potassium-ion batteries charge faster, perform better in cold weather, and are safer than lithium-based batteries. These features make them especially appealing for electric vehicles, where quick charging and safety are key.
According to Group1, switching from lithium to potassium in battery production doesn't require major changes to current manufacturing processes.
This means the new technology could be quickly adopted, potentially bringing potassium-ion batteries to the market sooner than expected.
