The World’s Smallest Battery in the Size of a Dust Grain Invented

by researchers in Chemnitz, Germany. to computers as small as a grain of dust A self-assembled battery was invented.

Researchers of the world smallest batteryIt was stated that the battery, which he stated to be the first of all, was able to assemble itself like a ‘Swiss roll’, also known as a roll cake. In the article published in the peer-reviewed journal Advanced Energy Materials, the battery, which was recorded to be smaller than one square millimeter, can be used in small devices in one go. hours of power reported to be available.

Battery self-rolls to refine power capacity

Small enough to fit on an electronic chip ‘micro battery on chip’ It is stated that the world’s smallest battery, called the on-chip 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, the battery, which is several hundred micrometers in size, increase power capacity It is stated that it can take the form of a cylinder like a ‘Swiss roll’ on its own.

The layers they are working on are very thin and fragile, and the technology required to wrap them is at the mass production level. not available Chemnitz University of Technology researchers stated that, for this reason, the tension between the layers when immersed in the liquid causes the layers to rotate around each other spontaneously, ‘micro-origami’ He states that they tend towards the technique of self-assembly, which is called self-assembly.

For all tap sizes of Swiss roll design typical Stating that it is a design, the researchers, for example, stated that Tesla batteries are also wrapped in a cylinder and as a result, they are larger than normal. 28 times more It is said to be able to store energy.

Full-size batteries such as Tesla batteries use a winding machine to create 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. As for Minshen Zhu, “As such, the material only to self-construct the appropriate structure permissible.” saves as.

In addition, Zhu, thanks to his inventions, thin-film batteries, less than a square millimeter states that it is possible to be in sizes.

A new era may begin for the world of science and medicine

Stating that the structure they invented can fit into the world’s smallest computer chips, the researchers said that 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; chips into ultra-flexible electronics, microcomputers, robotic systems, or the human body. in sensors believes it can be used.

In his articles, according to Bell’s Law, computer classes are approximately every ten years. shrunk 100 times Researchers pointing out that the reduction in battery sizes may lead to the beginning of a new micro-computer era, thus making it a good idea for science and medicine. a new era It means you can start.

In terms of the subject, his inventions are a tool for the development of micro batteries. milestone may be; However, Zhu stated that the team has much more to do to optimize the development of the devices. “These small batteries are very good for micro-robots or micro-implantable devices. additional power supplies it could be.” saves as.
