‘This type of fundamental research is important’

The batteries that power our electronics may be getting a powerful glow-up after researchers made a game-changing discovery to prevent deterioration in metal cells.

In July, Sweden’s Chalmers University of Technology

with longer ranges and even more electric aircraft.

Currently, lithium-ion batteries are one of the most common types of cells around, used for everything from smartphones to laptops to EVs and more. However, metal batteries are lighter and can provide more energy.

If they could be adopted on a broad scale, they could ultimately encourage and support the adoption of

According to

In short, replacing more gas-guzzlers with EVs and scaling up the options for sustainable flights (whether through electrification and/or cleaner alternative fuels) would go a long way toward helping the global community stay healthy and avoid the worst impacts of a changing climate.

in the university’s media release, in a metal battery, lithium metal replaces the graphite electrode (used for a traditional lithium-ion cell).

But one major issue has been the metal cells’ short lifespans because of the metal’s high reactivity. To solve this, the team used electroplating inside the battery, resulting in a “more predictable and stable electrode,” according to doctoral student Josef Rizell.

“By creating the metal electrode inside the battery, the metal never has the opportunity to react with impurities outside the battery,” the Chalmers University of Technology

The study, published in the Journal of
