zinc-air

Hearing aid power

Zinc-air refers to a type of battery that generates electricity through the reaction of zinc with oxygen from the air.

These batteries are lightweight and have high energy density, making them common in hearing aids and other small devices: She replaced the zinc-air batteries in her hearing aid.

The technology is also being developed for larger applications like electric vehicles.
