For wearable devices, batteries have always been a bottleneck. However, a "paper cell battery" manufactured by Korean researchers has brought about a turnaround for the above contradictory solutions.

According to reports from CCTV, the main production material for this “slide battery” is cellulose extracted from wood. The research team separated the cellulose into one ten-thousandth of the size of the hair and used it as the raw material to make the two poles and diaphragms of the lithium electronic battery.

As its name suggests, "paper battery" has a very good softness. It can even continue to work after being folded into a origami. It can be installed in equipment with more complicated internal space.

At the same time, the "paper battery" also overcomes the drawbacks of the traditional battery heating, safety is further improved, the service life is more than three times the ordinary battery.
