Navitas Systems Advanced Solutions Group (ASG) is at the forefront of research and development into the most promising “Advanced Lithium” and “Beyond Lithium” battery technologies. Funding for these research projects comes from within Navitas and East Penn, as well as from contract awards by a broad spectrum of customers including branches of the US Department of Defense, the Department of Energy, NASA, certain automobile and consumer electronics manufacturers, and Defense contractors. We partner with universities, national labs, and industrial partners (including small businesses) to accelerate advanced and beyond lithium battery technologies.
Among the various battery technology research projects, developments include advanced silicon and lithium metal anode, Ni-rich layered oxides (NMC, NCA), 5 Volt-class high-voltage cathode, lithium sulfur battery and solid state battery. Navitas scientists are also skilled at electrode manufacturing improvements such as “Advanced Drying Process” to fabricate thick electrodes (> 35mg/cm2), and solvent free “Dry Process” electrodes.
Our scientists also have expertise at high energy and high power cell design as well as creating optimized form factors, such as the novel “pancake” shaped lithium cell.

Navitas Systems’ Advanced Solutions Group (ASG) Research and Development team brings considerable knowhow in lithium ion cell and battery research, development, engineering and manufacturing, totaling hundreds of years of combined experience.
One of Navitas ASG’s core competencies is to develop and match the best cell chemistry to the application at hand, not just to re-package existing chemistries. As such, our group has developed a great deal of experience with many kinds of anode and cathode materials and has developed relationships with many materials vendors across the globe. Furthermore, we have a great deal of experience in optimizing core cell designs for specific purposes, such as high power, high energy, high temperature robustness, high cycle life, and high durability.
So when we interact with a customer about their problems and needs, this brainpower engenders confidence that our recommendations, proposals, programs and products are grounded in fundamentals. See the wide ranging capabilities utilized by our cell development team below.
Navitas ASG’s 48,000-square-foot Venture Drive Ann Arbor, Michigan facility houses world class materials science labs, cell testing, pilot scale electrode coating capabilities, a 720-square-foot dry room, wet lab, prototype assembly, machine shop, a 10,000 square-foot automated lithium cell production line, and a hardened cell test facility.
A partial list of the available research equipment follows:
Jar, attritor, and jet mills, controlled-atmosphere tube furnaces up to 6 inches in diameter, and drying ovens. Small mixers and K Coater for producing small electrodes for both coin cells and SLP’s (single layer pouch cells).
Semi-automated small format prismatic cell assembly line in a Scientific Climate Systems Inc. (SCSI) 720 square foot dry room (maximum 2 percent relative humidity), Toyo/MEGTEC slot die electrode coating machine with both IR and convection drying capability, Ross PDDM-2 slurry mixers, IRM Model 200 heated-roll calendaring press, Hohsen Type 2520 coin cell press, three glove boxes, spot and ultrasonic welders, and vacuum drying ovens.
The pilot facilities contain a semi-automated cell and production facility, and are a copy of that used in high volume production which has been qualified by commercial customers.
This pilot production facility features a pilot coater and cell assembly equipment, and is tooled and staffed to produce a variety of small to large format prismatic cells. The assembly equipment is operated in a 720 square foot dry room. The facility assures a highly reproducible assembly process, which eliminates noise associated with cell assembly to assure that any differences in performance can be attributed to the intended variables in our experimental designs. Because this facility has been built around state of the art cell production equipment, it offers an excellent foundation for establishing a pilot or limited volume production capability.
Over 400 Maccor automated test channels (up to 35V, 240A), Solartron potentiostats for EIS, CV and other electrochemical test methods, and multiple environmental chambers (-70 to 200°C). These test channels and environmental chambers support electrochemical performance evaluation using commercially relevant prototype cells and test protocols.
Navitas has a broad portfolio of Intellectual Property, both Trade Secret and Patents. Battery innovations span the spectrum, from advanced chemistries, unique cell shapes, fast charging, to cell manufacturing process improvements. For battery manufacturers contemplating building new facilities, we have the technologies which can increase “speeds & feeds” of your production line, and improve battery performance characteristics.
