The smallest battery in the world, the size of a grain of salt

Telset.id, Jakarta – Batteries are identical to their large size, but a number of researchers have succeeded in developing the smallest battery in the world with dimensions similar to a grain of salt.

Reported Telset from BGR on Friday (4/3/2022), technological innovation departs from the assumption that in the future, the size of technological devices will be smaller so that it is necessary to make small batteries to support these devices.

Therefore, researchers from Germany and China, to be precise from Chemnitz University of Technology, IFD Dresden, and Changchun Institute of Applied Chemistry collaborated to create a small battery device or micro battery the size of a grain of salt.

The size of the battery is not explained but this battery is claimed to be the smallest battery in the world. The battery is also claimed to be able to provide power for small technological devices such as biocompatible sensor systems placed in the human body.

Micro batteries have a design similar to cylindrical batteries that we often encounter in the market. The difference is that the size of the battery is very small and is made of a thin film rolled into several layers or the so-called micro origami technique.

The micro origami technique is done so that the battery is able to offer a solid amount of power without taking up too much space.

That way the battery can fit into a smaller space while also providing more than enough power for the technology devices it’s connected to.

While it’s not in any technology yet, we could start seeing it appear in other technologies in the future, especially those that fit into small places and require a lot of power behind them.

Currently, this micro-battery, the size of a grain of salt, made in Germany and China, has never been tested with technological devices.

But according to another study of the world’s smallest battery a micro battery must meet two basic requirements for integration into small technological devices such as microcomputers.
