3D-Printed Lithium-Ion Battery Is the Size of a Pinhead
7/9/2013

Harvard University, the University of Illinois at Urbana-Champaign, and visiting researchers from South Korea have demonstrated the ability to 3D print a pinhead-sized battery. These interlaced and stacked electrodes were printed layer by layer to create the working anode and cathode.(Source: Jennifer A. Lewis/Harvard University)

3D printing as a disruptive technology

It seems there is no end to what can be done using 3D printing, which is proving to be a truly disruptive technology and has the potential to be as game-changing as the Internet itself in terms of its effect on how we do things. This research shows advances not only in this area, but also continued efforts to improve lithium-ion battery chemistries and design forms. Will be interesting to see if something like this makes it out of the research lab.

Very cool, how many uAH can it store?

Yikes, in the photo it appears to be just 800 microns wide. That's really small. I, too, wonder how many microamp-hours it can store. Sounds like its main application is to power sensors.

I don't know offhand how many microamp hours it has, guys...here is the link to the press material about it: http://www.seas.harvard.edu/news/2013/06/printing-tiny-batteries


There is also a video. I'll email the researchers and try to find out.

This sounds like quite a breakthrough, Elizabeth. What are the 3D printing method and materials they used? The mention of "inks" sounds like it might be a thin-film printed electronics method, such as that used by Optomec in its conformal electronic printing.

But that's printed 3D electronics, not 3D printing.

@Elizabeth – I think now its high time for us to ask the question "What cant the 3D printer print?". I think this is one of the best innovations for the past decades. What more could we expect from technology.

This will be of great use in implantable medical devices like ICD or neurostimulators. Thanks a lot for sharing this info.

I agree, shehan. It's getting into the realm of the ridiculous nearly when you think of all the things being 3D printed. NASA is even 3D printing things in space! Pretty incredible. Let's see what they think of next!

Thanks for your comment, vimalkumarp. It's good to know that this type of battery could be useful in real-world applications. Let's hope it makes it out of the lab and into these devices.

powering the implantable medical device is a challenge and formfactor is a concern. This will boost the medical device implantable power segment.
