Foldable batteries could replace double batteries in foldable phones

Foldable phones just surfaced this year and there is a high chance that they will be around for the next couple of years if everything goes well. At this point, these devices use two batteries instead of one larger energy pack. Thanks to a team of researchers from ETH Zurich, this could change soon. The team developed foldable batteries, which could easily fit into both foldable phones and wearables. Manufacturers will be able to bend, fold or stretch the batteries according to their needs, without interrupting the power supply.

Even though the foldable phones are the first ones to come to mind when thinking of possibilities to use the foldable batteries, these arențt the only gadgets that could benefit from them. Rollable displays are also on the market and with the new foldable batteries, they could become even more popular in the future. Also, these batteries could totally change the design of smart wearable, as manufacturers could more easily fit them into bracelets, and basically wearable devices of any shape. The foldable battery is basically a rather soft device that is made of two stretchable current collectors which embrace an anode, PDMS frame and sealing, a hydrogel electrolyte, and an anode.

At this point, there is only a prototype, but given all it can be used for, we wouldn’t be surprised to see the new technology in all the upcoming devices that would need a bendable battery instead of a rigid one. Who knows? maybe starting from the foldable batteries, manufacturers will come up with more and more gadgets that could use them. In technology everything is possible, we just have to patiently wait and see what comes our way. It might take a few years until the new batteries go into mass production and it’s not quite clear yet how much they will influence the price of the gadgets they will be set in. Even so, we are eagerly waiting to see what they will land in.
