Tie a knot to your new and powerful slim smartphone

Flexible batteries have been around for quite a while now, but the main problem is that most of them must be very thin and only flex one way. LG Chem has just demonstrated a new type of battery that looks like an ordinary cable and that can be flexed, bended and even tied in a knot.

One thing our readers must know is that a battery’s every capacity is roughly directly proportional to its volume.

Therefore, thin, flexible batteries have the disadvantage of having quite a modest volume that can’t hold too much energy, and the fact that they are rather made of polymers makes them less energy dense than metal-based batteries.

LG’s solution can reportedly be flexed and bended in any way, while having the advantage of having a bigger volume and being made with materials that allow that volume to have a greater energy density, as this cable-battery is metal-based.

The solution can be applied to make wearable batteries woven in our clothes. It can also allow for a much wider range of battery formats and slimmer devices with greater battery life.
