Researchers in Chemnitz, Germany, have invented a self-assembling battery that can fit into computers as small as a grain of dust.
It was stated that the battery, which the researchers say is the smallest battery in the world, can assemble itself like a ‘Swiss roll’, also known as a roll cake. In the article published in the peer-reviewed journal Advanced Energy Materials, it was reported that the battery, which was recorded to be less than one square millimeter, can power small devices for hours at a time.
Battery rolls up on itself to refine power capacity
‘micro battery on chip’ (on-chip) meaning small enough to fit in an electronic chip It is stated that the world’s smallest battery, called the microbattery, consists of several thin layers of electronically charged polymer films stacked on top of each other and electrode columns that conduct current through the film. In addition, it is stated that the battery, which is a few hundred micrometers in size, can self-roll like a ‘Swiss roll’ in order to increase its power capacity.
Chemnitz University of Technology researchers, who stated that the layers they are working on are quite thin and fragile and that the technology required to wrap them is not available at the level of mass production, therefore, when immersed in the liquid, the tension between the layers causes the layers to rotate spontaneously around each other, ‘micro-origami’. He states that they tend towards the self-assembly technique called ‘.
Stating that the Swiss roll design is a typical design for all battery sizes, the researchers state that Tesla batteries, for example, are also wrapped in a cylinder, and as a result, they can store 28 times more energy than normal.
full-size batteries such as Tesla batteries use a winding machine to form the Swiss roll structure; However, stating that there is no tool on a micro scale for this process, researcher from Chemnitz University of Technology Dr. Minshen Zhu, on the other hand, said, “As such, the material can only be allowed to form the appropriate structure by itself.” saves as.
In addition, Zhu states that, thanks to his inventions, it is possible to make thin-film batteries smaller than a square millimeter.
A new era may begin for the world of science and medicine
Researchers expressing that the structure they invented can fit into the smallest computer chips in the world, so that these computers can last up to 10 hours. He states that a rechargeable cylindrical energy storage system that can provide power can be obtained. Researchers who stated that such small chips are used for vital medical devices; He believes the chips could also be used in ultra-flexible electronics, microcomputers, robotic systems, or sensors that go inside the human body.
In their article, researchers stating that computer classes are shrinking about 100 times every ten years in accordance with Bell’s Law, say that the reduction of battery sizes may lead to the beginning of a new micro-computer era, thus starting a new era for science and medicine.
; “These small batteries can be very good additional power sources for micro robots or micro implantable devices,” Zhu said, adding that the team still has a lot more to do to optimize the development of the devices. saves as.
