“Paper battery” is freshly baked, and its service life is 2 times that of lithium battery.

The “paperpaper” (powerpaper) developed by the University of Linköping in Sweden, although small in size and slim in size, is 8 to 10 times the capacity of ordinary mobile phone batteries, and can provide users with long-term stability without any difficulty. Battery output. The battery has been tested for more than 2,000 times, and there is no obvious loss, and the service life is twice that of the lithium battery.

If Alessandro Volt, who invented the first "battery" 220 years ago, could see that the thickness is less than 1 mm, but the size is only A4 paper, but the capacity is 26800 mAh." Paper battery, should also send such feelings!

The “paperpaper” (powerpaper) developed by the University of Linköping in Sweden, although small in size and slim in size, is 8 to 10 times the capacity of ordinary mobile phone batteries, and can provide users with long-term stability without any difficulty. Battery output. The battery has been tested for more than 2,000 times, and there is no obvious loss, and the service life is twice that of the lithium battery.

Because the material of this "paper battery" is a special material synthesized by nanofibers, its texture is very soft and its hand feel is similar to ordinary paper. Moreover, under the action of a high-pressure water column, engineers can reduce this "paper" fiber to a thickness of 20 nanometers, which is only 1/5000 of the diameter of human hair. It also has excellent ductility and stability and maintains a good discharge after multiple folds.

In fact, in 2006, the research team led by Chinese scientist Zhang Xiachang has designed the world's first "ultra-thin paper battery." They use electronic component printing technology to print different functional slurries on semi-sheet substrates to form the positive and negative electrodes of the battery and discharge them through relevant chemical reactions. In theory, the “paper battery” designed by Zhang Xiachang's team can provide a long-term, stable power output environment, and can quickly release high-energy power like a supercapacitor, thus making up for multiple short plates of traditional batteries.

“A traditional battery combines several individual components in a three-dimensional manner, and the 'paper battery' prints all the components in a single structure, making it more efficient.” Zhang Xiachang said, ideally, a single The "paper battery" has a voltage of 1.5 volts and can be combined to form a higher voltage battery in series. The shape, size, thickness and position of the battery can be adjusted according to specific requirements for use in various types of electrical appliances.

Because some technical means were not yet mature at the time, some technical bottlenecks were difficult to overcome at one time, resulting in the battery not discharging time and power. It is not widely used in digital cameras, mobile phones, watches, etc., and is mainly used in large electronic products. In the field of "radio frequency identification" with low power consumption.

With the continuous advancement of electronic technology, new electronic products such as folding mobile phones, folding watches, and ultra-thin portable computers are constantly coming out. The "paper battery" technology is also constantly improving and innovating, bringing the market demand closer.
According to the design concept of Zhang Xiachang team, combined with the latest technical means, the latest "paper battery" developed by the research team led by Professor Xavier Crispin of Linköping University in Sweden has made a qualitative leap in stability and practicality. In addition, the "paper battery" encapsulated by a conductive polymer coating is not only waterproof, but also can be recharged hundreds of times, and it takes only a few seconds per charge.

So, what changes can the “paper battery” with many advantages in one place bring us?
For example, the mobile phone that everyone is concerned about, due to the special physical properties of its internal lithium battery, the fuselage is too thick, the standby time is too short has been a technical problem that many design teams can not overcome. All of this will be solved by the soft and cuttable characteristics of the "paper battery", the slimness of the paper, the large capacity, and the stable output power.

In addition, the military fields that all countries attach great importance to will also be open to the arms. Perhaps in the near future, all kinds of portable radios, base stations, and combat command systems loaded with "paper batteries" on the battlefield will be more compact and lighter; vehicles driven by "paper batteries" will become rid of bulky traditional energy sources. It is quicker and lighter; the medical rescue unit does not have to consider the power supply problem, and can complete one operation with the help of a “paper battery”; the drones in the sky and the unmanned boats in the sea will have long-lasting life because of the “paper battery”. Ability to expand the scope of reconnaissance...
