Israeli Gadget Claims To Charge Your Phone In 30 Seconds With Amino Acids

The dissipating green rectangle hovering at the top of your screen is, for most, a major source of anxiety. Shrinking to red before fading to black, it can force you into desperate positions, like patiently huddling over a spare powerpoint, as if warming yourself near a campfire. Or worse still: briefly not using your phone.

Not anymore.

On Monday at the Think Next symposium in its hometown of Tel Aviv, StoreDot demonstrated a prototype biological battery — roughly the size of two cigarette packs — which charged a Samsung Galaxy S4 in about 30 seconds.

The rapidly-charging smartphone battery is fabricated with chains of amino acids known as peptides. The same naturally occurring protein building-blocks that are at the heart of professional sports’ clubs controversial supplement programs.

When used to construct semiconductors for batteries, peptides charge faster and more reliably than traditional materials.

Typically a smartphone battery stores energy in structures known as quantum dots or nanodots. These can be made of inorganic semiconductors such as silicon; or other similar structures using cadmium selenide or zinc sulphide.

In 2010 researchers Charlotte Hauser and Shuguang Zhang wrote in the journal Nature that quantum dots could be formed with other materials, including peptides. They found a number of advantages, including causing the environment less harm. More importantly, the nanodots are cheap and easy to produce at a high purity.

This is specifically useful for smartphones.

Inorganic semiconductors produce randomly structured nanodots, essentially causing the battery to degrade over time. On the other hand, peptide semiconductors create more uniform structures, time and again, giving the battery a higher efficiency and longer shelf-life.
