Battery Revolution: 3D printing transforms into various shapes

In general, the TV that everyone has seen is always a square or a round piece. But with the development of 3D printing technology , some scientists claim that TV can also be transformed into a variety of more interesting shapes to better use in a variety of wearable technology products.

Recently, researchers from the Department of Energy Engineering, National Institute of Energy and Chemical Engineering, National Institute of Technology and Technology (UNIST), Korea, published a book called "Printable Solid-State Lithium-Ion Batteries in Nano Letters: Moving to a Variable with Aesthetics Printable Solid-State Lithium-Ion Batteries: A New Route toward Shape-Conformable Power Sources with Aesthetic Versatility for Flexible Electronics. The author of this paper is Se-Hee Kim, Keun. - Ho Choi, Sung-Ju Cho, Sinho Choi, Soojin Park and Sang-Young Lee. This paper discusses the possibilities of a new, customizable battery.

Researchers say the lithium-ion battery will be able to print anywhere in a more convenient form. They call this new type of power supply a PRISS lithium-ion battery that can print continuously on any object with a complex geometry to create a complex structure. Researchers point out that these new power supplies will far outweigh the traditional battery technology.

To create this new super battery, scientists used a combination of the following:

̇SCE paste

Bismuth electrode paste

̇UV curing acrylate polymer

High boiling point electrolyte

But scientists are looking to make these batteries with other, more advanced technologies to make them more convenient and economical to manufacture.

“In order to expand the range of applications for this printable battery, we are currently considering a variety of printing technologies.” Professor Sang-Young Lee, the head of the project, said, “Inkjet and 3D printing are within our consideration. Because they make it easy to manufacture power supplies with multi-dimensional/multi-scale complex structures, but the more pressing prerequisite is that every printing technology needs to meet the rheological requirements of thank you for printable battery components without damaging them. Electrochemical performance. Our team recently achieved some interesting results in the application of inkjet and 3D printing technology to make these printable batteries. This will bring the application of rechargeable power to a new field we have never seen before. ""

Using the advantages of these materials and 3D printing, the researchers were able to remove some extra steps and traditional materials that limited the battery to other shapes. Obviously, the "shell" of a conventional battery is specifically designed to avoid leakage of acid or other materials in the battery and to keep the electrodes apart. But with the emergence of new structural forms, these problems are no longer a problem.

Even more amazing is the fact that the mixing of SCE paste and electrode paste enables a completely new application. For example, the conductive mixture can even be used with a template for some decorative designs, such as letters or shapes. They also power the LEDs through connectors. And they are very powerful and can retain up to 90% after 30 cycles. However, scientists are still working to further optimize their efficiency.

“All battery components, such as cathodes, anodes and electrolytes, can be printed into any object with complex geometries, allowing the battery to be seamlessly integrated into any complex shaped object,” says Li.

As shown in the figure above, scientists used this technique to create a heart-shaped battery and spell out the word PRISS.
