Storing Electricity in Paper

The new cellulose-polymer material has set a new world record in simultaneous conductivity for ions and electrons, which explains its exceptional capacity for energy storage. It also opens the door to continued development toward even higher capacity. Unlike the batteries and capacitors currently on the market, power paper is produced from simple materials – renewable cellulose and an easily available polymer. It is light in weight, it requires no dangerous chemicals or heavy metals and it is waterproof.

The Power Papers project has been financed by the Knut and Alice Wallenberg Foundation since 2012.

”They leave us to our research, without demanding lengthy reports, and they trust us. We have a lot of pressure on us to deliver, but it’s ok if it takes time, and we’re grateful for that,” says Professor Magnus Berggren, director of the Laboratory of Organic Electronics at Linköping University.

The new power paper is just like regular pulp, which has to be dehydrated when making paper. The challenge is to develop an industrial-scale process for this.

”Together with KTH, Acreo and Innventia we just received SEK 34 million from the Swedish Foundation for Strategic Research to continue our efforts to develop a rational production method, a paper machine for power paper,” says Professor Berggren.

Rules of Thumb: Design007 Magazine, November 2024

11/11/2024 | I-Connect007 Editorial Team
Rules of thumb are everywhere, but there may be hundreds of rules of thumb for PCB design. They’re built on design formulas, fabricators’ limitations, and tribal knowledge. And unfortunately, some longtime rules of thumb should be avoided at all costs. How do we separate the wheat from the chaff, so to speak?

Connect the Dots: Best Practices for Prototyping

09/21/2023 | Matt Stevenson -- Column: Connect the Dots
PCB prototyping is a critical juncture during an electronic device’s journey from concept to reality. Regardless of a project’s complexity, the process of transforming a design into a working board is often enlightening in terms of how a design can be improved before a PCB is ready for full production.
