Most of the batteries we use these days, whether rechargeable or not, are generally self-contained affairs. They come in a sealed package, with the anode, cathode, and electrolyte all wrapped up ...

Although it's always best to reuse and recycle, many small, simple, low-power electronic devices tend to be single-use. A new paper battery could make them more eco-friendly, as it's activated by ...

(Nanowerk News) A team of researchers at Empa developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use ...

A thin-film printed battery, designed for one-time use after activation by a few drops of water, has minimal environmental impact when it is exhausted. The need for single-use, low-capacity batteries.

Discarded electronics are piling up fast, pushing researchers to explore creative ways to reduce this e-waste. Now one team has crafted a water-activated disposable battery made of paper and other ...

It sounds impossible: Just add water to a piece of paper and get energy. Researchers at Empa, a Swiss research institute, devised a proof of concept for a water-activated disposable battery powered by ...

Researchers at Empa developed a water-activated disposable paper battery that could be used in low-power, single-use disposable electronics such as smart labels for tracking objects, environmental ...

The HydraCell Power Cube provides instant power for light and charging by simply adding saltwater. Watch the demonstration video below to learn more about the HydraCell available from Kickstarter.

The battery, devised by Gustav Nyström and his team, is made of at least one cell measuring one centimeter squared and consisting of three inks printed onto a rectangular strip of paper. Salt, in this ...
