Graphene 3D Lab showing prototype 3D printed battery; potential for structural batteries

Graphene 3D Lab Inc., which develops, manufactures, and markets proprietary graphene-based nanocomposite materials for various types of 3D printing, including fused filament fabrication, has a 3D printable graphene battery. CEO Daniel Stolyarov, presented the prototype 3D printable graphene battery at the Inside 3D Printing Conference in Santa Clara, CA last week.

Graphene 3D Labs combines graphene nanoplatelets with thermoplastics used in FFF (fused filament fabrication) 3D printing, ultimately resulting in a functionalized 3D printing filament offering electrical conductivity. Currently, the process requires the separate printing of individual components—i.e., cathode, anode, electrolyte. However, a true multi-material 3D printer would enable the printing of the entire battery in one single print, the company notes.

Graphene 3D Lab recently submitted a provisional application for a patent to the US Patent and Trademark Office for recent innovations in the materials and methods of 3D printable batteries.

The application filed by Graphene 3D has the potential to play an important role in achieving the ability to print electronic devices due to the necessity of providing a power source. Expanding our IP portfolio in this area is an important step in keeping with Graphene 3D’s primary goal of creating an ecosystem for 3D printing functional devices with advanced materials.

The graphene-enhanced materials that have been developed by the company allow the 3D printing process to be used to fabricate a functioning battery which may be incorporated into a 3D printed object during the build process. A demonstration is in the video below. The prototype currently reaches the same voltage as a commercially available AA battery.

The company says that its 3D printed graphene battery potentially could outperform a conventional battery because the shape, size and specifications can be freely adjusted to fit the particular design of a device. Graphene 3D envisions printing batteries on demand and in remote locations, using the technology to 3D print supercapacitors that can be recharged much faster than the conventional battery, or printing batteries that are incorporated in the body of car.

Researchers in Sweden are exploring the use of carbon fiber as an active electrode in a multifunctional structural Li-ion battery in an electric car; i.e., electrical storage is incorporated into the body of the car. Carbon fiber material is a good candidate for structural electrodes since it has high specific tensile stiffness and ultimate tensile strength (UTS) as well as high lithium (Li)-intercalation capability.

The concept of such a multifunctional structural vehicle battery has attracted a great deal of other research interest from a range of organizations, including Volvo Cars and the US Advanced Research Projects Agency - Energy (ARPA-E), which awarded a total of $8.75 million to four separate projects (led by Stanford University, UC San Diego, Arizona State University, and Penn State) to develop multifunctional structural batteries for vehicles as part of its RANGE program for transformative EV storage.

Graphene 3D has three US patent applications pending for its technology.

Structural batteries may become an ideal solution for compact future e-cars with Extended range.

Again studies and experimentations. When will we see an article that show an actual result that is actually commercialized instead of dubious findings that will never reach the real market. It's been years that I read this website and I have still to rely on my gasoline car with a technological basis that is 100 years old. Im sure that If I stop reading this website for a year or two I will miss nothing at all and I can go in youtube and listen free music instead and stop losing my time here.

If it will help you cheer up Gor, I do recommend it, 'cause all this good news seems to be bringing you down. Considering that research and development is big part of what this site reports, I can imagine what a bummer that is.

I want to see the breakthrough battery on sale too. But until it's ready to ship, I just keep reading, like a lab mouse pushing the button for more cheese. Hoping... Waiting... For the guys and gals in white coats to hurry up and finish their experiments...
