Fiction | The new lithium-ion battery that is recharged 1,000 times faster


Scientists of the University of Illinois at Urbana-Champaign have created a new lithium-ion battery, which is 2,000 times more powerful than the modern counterparts. Moreover, the researchers also report that the battery is being charged 1,000 times faster.

According to the researchers, this is not just a new evolutionary step in the development of technology.

“It’s a completely new high-performance technology that goes far beyond the current paradigm of energy sources. It gives us new possibilities, “- said the scientists.

Now we have to choose between the power (watts) and energy density (Wh). This is a compromise that has to go in today’s power supplies. Supercapacitors can release a lot of energy, but only for a few seconds. At the same time, the peak power output of the fuel cell is limited, they can store a huge amount of energy. Currently, this issue is particularly relevant, since most modern technologies and devices (smart phones, computers, electric cars ) are important in both. For demanding tech lithium-ion batteries are ideal solutions, but even the best batteries are forcing engineers to compromise in creating a variety of new devices.

“This is a completely new view on the batteries that can provide much more energy than anyone else ever could and think. During the last ten years in electronics transformed microelectronics. Despite the fact that major components of modern computers every year reduced in size, the battery still continues to fall behind. This technology will turn everything upside down and put the power supply in a system with other components “- said project leader Professor William King.

Established in the University of Illinois battery has a capacity comparable to that of supercapacitors and typical for nickel-zinc or lithium-ion batteries stored energy. According to a university press release, this battery allows wireless devices to transmit a signal up to 30 times more. More interestingly is that if the battery is 30 times less than their counterparts. And finally, as mentioned above, it is charged to 1,000 times faster than today’s lithium-ion batteries.


How can this be explained, you ask? These incredible features are explained by the new structure of the cathode and the anode, and which was developed by scientists. All modern lithium-ion batteries are different from the large two-dimensional graphite anode and cathode of a lithium salt. In turn, created by scientists of the University of Illinois battery is different three-dimensional porous anode and cathode. Its structure can see the detail in the picture above. To create a new electrode structure, scientists have recreated the structure of polystyrene (Styrofoam) on a glass substrate. On polystyrene imposed electrolytic nickel and then tin alloy electroplating – nickel anode and a cathode manganese dioxide. In the figure above, all is well illustrated.


Due to the large contact area of ​​porous electrodes scientists were able to increase several times the chemical reactions taking place, providing a big boost charging and discharging (power). Scientists have used this technology to create a battery the size of a normal button. In the figure above, it is compared with the battery Sony CR1620. The indicator of the energy density of the new items a little less, but power rating is 2000 times greater.

In practice, this technology will be used in the batteries of various consumer electronics. Imagine smart battery with a thickness comparable with the thickness of the credit card to be charged for a few seconds. This technology also find application far beyond the consumer electronics market, for example, in medicine or in the development of lasers.

However, as quickly as possible to begin the commercialization of the project, the University of Illinois scientists have yet to prove that by using this technique you can create a bigger battery, and their cost is not too high. Perhaps before we will see the lithium-air batteries or batteries with silicon nanowires, about which more detail can be found here .
