SCIENCE & TECHNOLOGY

When changing tools leads to creative outcomes

This water-based battery is a safe and cost-effective alternative to the Li-ion technology.

No “corners were cut” when designing this innovative aqueous battery: it is safe (it does not short-circuit nor catch on fire) and maintains its voltage even when damaged. (Source. Distributed under a Creative Commons Attribution 4.0 International License. Original video sped up by author)


SCIENCE NEWS

Brittle materials sometimes break randomly and other times they don’t. Scientists have finally figured out why.
