MIT Engineers Develop Tiny Zinc-Air Batteries to Power Cell-Sized Robots

MIT engineers have made a significant breakthrough with the development of a tiny zinc-air microbattery, measuring just 0.1 millimetres in length and 0.002 millimetres thick, about the width of a human hair. This innovative battery captures oxygen from the air to oxidise zinc, generating a potential of up to 1 volt, which is sufficient to operate small circuits, senso…
