Technology allows everything to be more compact and smaller. Just look at the cellphone that used to be as big as a gaban, now it fits in the palm of the hand. Well, scientists are also developing batteries that are getting smaller and smaller, about the size of a grain of salt!
A group of scientists at Chemnitz University of Technology think that we will need smaller batteries to power devices that are also getting smaller in size. In collaboration with IFD Dresden and the Changchun Institute of Applied Chemistry, the team was able to provide answers to the needs of micro batteries.
The smallest battery in the world is smaller than a grain of dust. As such, it is capable of powering very small devices such as biocompatible sensor systems housed in the human body.
Unlike other batteries with micro size, this battery is claimed to be different. Quoted from BGR, Thursday (3/3/2022) this micro battery has its own assembly process. This process is known as micro-origami. Thus, the micro battery is more like a standard cylindrical battery.
According to a study on the world's smallest battery, the new design implemented this time allows the battery to meet two basic requirements for integration into a microcomputer. First, it must have a minimum energy density of 100 microwatt-hours per square cm. In addition, the battery also needs to offer monolithic integration with other electrical circuits on the chip.
Similar to rolls
Uniquely, this battery design is inspired by a Swiss roll cake or also known as a roll cake. This cake is designed to roll with a layer of cream inside.
Just like rolls, these batteries are made of a thin film layer that is rolled into several layers. This allows the battery to offer a solid amount of power without taking up too much space.
Borrowing such a design, the battery can fit in a smaller space while providing more than enough power for whatever is flowing from it.
Although it has not been implemented in any technology, scientists predict that this battery will appear in future technologies, especially those that have limited battery storage space but require a lot of power.
