In era of technology everything is getting smaller and smaller. From 1KB of hard-disc to 1 Tb of hard-disc with size 20 times less than previous one, battery is also getting smaller and efficient. A new technique is developed in last few years called paper batteries with the help of nanotechnology. They can bet cut down, folded to give multipurpose use. It the most flexible, most thin and efficient storage system. It consists of cellulose paper, carbon Nano tubes as a basic element. It acts as high energy battery and capacitors. With help of this advances in construction it provides steady power production and energy with nontoxic properties.

The biggest advantage of this battery allows it to be used in modern appliances such as foldable mobiles, wearable watches and AR glasses. This don’t only give compactness but more flexibility and user access to end server. Ultra-portability and compactness allow us to enter to the world of new future of advance technologies. Not only digital devices it can also implemented in medical. It can be placed in body and used for different applications. It also gives flexibility and comfort, since it is not that much bigger than the previous batteries.
