Researchers Develop Flexible Batteries for Foldable Devices


Nowadays, smartphones continue to develop and diversify, while the foldable smartphone designs, which once seemed to be a dream, began to appear on the market. One of the obstacles to the flexibility of these folding devices was the battery, but with a new technology, it seems to be a thing of the past.

One of the biggest obstacles for manufacturers when designing a foldable phone is the battery … Unlike foldable displays, we don’t have a foldable battery so far. This may change with the idea of ‚Äč‚ÄčNied stretchable batteries de by Markus Niederberger, a professor at the ETH Zurich Technical University in Switzerland.

As the name suggests, these batteries can be folded, bent and stretched, which seems ideal for smartphones and tablets with unusual form factors. Think of the next generation Samsung Galaxy Fold or Huawei Mate X without battery limitation. Isn’t that amazing? The battery appeared in the article Advanced Fully Integrated Design of a Flexible Solid State Lithium Ion Battery Advanced published in Advanced Materials magazine. He uses a new kind of material discovered by Xi Chen, the author of the article.

So how does it work?

You should be wondering how this new battery technology works. It uses a new electrolyte that acts as a means of lithium ions to advance in one of the directions based on the energy flow. The collectors for the anode and cathode are made of bendable carbon. For those who want to know the materials used, the anode used in the battery is made of vanadium oxide and the cathode is made of lithium manganese. Microscopic silver flakes were added to these surfaces to act as a conductive layer.

Let’s look at the internal structure of the battery

As of now, the battery is not ready to be placed in future foldable phones because scientists are looking for a suitable adhesive to keep all layers intact. We have to wait until scientists find a solution for this. Once they find a suitable solution, a whole new range of possibilities for the physical design of foldable smartphones can be opened.
