Battery fires are rare, but when they happen, they require enormous amounts of firefighting resources. The problem is caused by the flammable electrolyte, which can generate its own oxygen in a ...

In a newly published study, we describe our design for a self-extinguishing rechargeable battery. It replaces the most commonly used electrolyte, which is highly combustible—a medium composed of a ...

By modifying affordable commercial coolants to function as battery electrolytes, we were able to produce a battery that puts out its own fire." The self-extinguishing electrolyte performed well in ...

Rechargeable batteries are great for storing energy and powering electronics from smartphones to electric vehicles. In cold environments, however, they can be more difficult to charge and may even ...
