In a step designed to maintain U.S. research and development momentum in next-generation battery technology for electric vehicles and beyond, the University of Michigan has expanded its open-access U-M Battery Lab with a second off-campus facility.
Open to both academic and industry researchers, Battery Lab 2.0 adds 4,000 square feet of lab and production space on Ellsworth Road in Ann Arbor. Its machinery lineup includes an industry-standard automatic laser welder for assembling battery modules and packs. And its three-megawatt-hour lithium-ion battery production line is believed to be the highest-capacity pilot-scale line based at a university.
"In the decade since the original U-M Battery Lab opened—the first of its kind in the country and now the only one in the heart of the auto industry—it's been a critical enabler. It's helped to catalyze many of the battery advancements now powering today's EVs," said Alan Taub, director of the U-M Electric Vehicle Center and professor of materials science and engineering and mechanical engineering.
"But demand has consistently outpaced capacity, which is why we've expanded—giving researchers even more room to build the future."
The lab's capabilities include prototyping, testing and manufacturing multiple lithium-ion, solid-state and next-generation rechargeable batteries in both pouch and cylindrical formats. These common formats have applications in grid storage, personal electronics, backup generators, drones and defense technologies, for example, as well as EVs.
Makerspaces like U-M's Battery Lab provide opportunities for companies without in-house labs or manufacturing facilities to test ideas, tailor prototypes and make products. Lab users have included established companies like Ford, Mercedes-Benz and PPG Industries, as well as startups like MIT-spinout Nanoramic.
"We bridge the 'valley of death'—the period between a promising concept or early-stage technology and commercial production. We provide the infrastructure, equipment and expertise to prove you have a product," said Greg Less, battery lab director.
"We've supported major automakers, and we also give smaller operations a seat at the table. The more new ideas that see the light of day, the faster technology advances. And what we offer them is as close to industrial prototyping as you can get."
Nanoramic describes the lab as "pivotal in advancing their R&D efforts." Late last year, the company raised $44 million in a round of financing co-led by GM Ventures and with Samsung Ventures participating.
The original Battery Lab opened on U-M's North Campus in 2014. Almost immediately, and ever since, the $9 million facility has been fully booked by academic and industrial researchers from around the globe. Its location makes it accessible to a variety of industries.
"Being near the automotive industry is a symbiotic benefit," Less said. "They don't have to increase their internal capability because they can take advantage of what we have. And when they come to campus, we learn from them."
The lab expansion, located on Ellsworth Road, includes:
-
A 4,000-square-foot dry room where moisture can be precisely controlled, allowing researchers to mix and coat extremely sensitive, next-generation materials.
-
An increased maximum mixing volume of 30 liters, up from 10 liters at the original battery lab, allowing for the production of larger, and more, batteries.
-
A lengthened coating system of 6 meters, enabling faster application and more control over drying of the electrode material during cell production.
-
Ability to produce both the 21700 format cylinder batteries as well as the 100x150-millimeter format pouch batteries. These larger cell formats are more representative of today's automotive cells.
-
An automated laser welder for assembling cells into larger groups, called modules and, ultimately, battery packs—just as they'd be deployed in the marketplace.
Battery Lab 2.0 is a stopgap during design and construction of a $60 million on-campus battery lab that will be an addition to the U-M Transportation Research Institute building. Funding for this expansion as well as the future on-campus lab comes from the state of Michigan $130 million contract that established the Electric Vehicle Center in 2023.
Battery Lab 2.0 is located off U-M's campus, near Ann Arbor's southern border, which allows industrial users easier access. The new equipment was manufactured by Energy Tech Solution.
