Paper battery: flexible and foldable, 10 times the capacity of lithium battery

With the advent of folding mobile phones such as Samsung Galaxy Fold, Huawei Mate X, and FlexPai. While folding screen mobile phones can bring us excellent visual effects, the thickness of the body and the standby time have always been problems that cannot be overcome at present. In the single-screen state, the thickness of the body is still far greater than that of a regular-sized mobile phone. The main reason is that the size of the camera is limited, and the size of the battery is limited.

Recently, Linkoping University in Sweden developed a super battery Power Paper, also known as 'paper battery

The battery has an extremely thin thickness, excellent ductility and stability, and can still maintain good condition after repeated folding. Although the battery is small, its capacity is 26,800 mAh, which is about ten times the capacity of the iPhone battery to ensure that the phone has a long-lasting battery life.

The realization principle is: a reasonable ratio of conductive polymer and plant cellulose, glycerin and other substances to achieve the battery effect.

The battery has been tested in the laboratory for more than 2000 times without any loss, and its life span is more than twice that of a lithium battery.

Power Paper has received 280 million yuan in funding for the overall realization of Ru0026D and mass production.
