Researchers Devise New Method to Extend the Lifespan of Lithium-Ion Batteries
A new South Korean study could pave the way for electric aircraft to make longer flights and require less frequent battery replacements.

Among the biggest challenges that electric aircraft developers are facing today is the limitations of battery technologies. Unless scientists come up with new ways to make smaller and lighter batteries that hold more charge for longer periods of time, electric aircraft will only be able to make short, regional flights before needing to recharge. 

To make matters more complicated, batteries degrade over time, reducing the amount of charge they can hold and shortening the battery life. Just like the lithium-ion batteries in cellphones and electric cars wear out every few years, electric aircraft using today’s battery technology will need their aging batteries replaced on a regular basis. However, new research suggests that a minor modification to existing lithium-ion batteries could extend their lifespan, reducing the need for frequent battery replacements.
