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 developed 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 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.
