University of Michigan Battery Lab

Working With Us

User Resources

The Battery Lab is an open user facility capable of testing single cells, handmade cells, and batches of up to 25 semi-automated pilot-line cells.

For future users, it is required you complete the University of Michigan laboratory safety training. To do so, follow these steps:

1. Go to http://ehs.umich.edu/education/ehs-training/

2. Complete steps 1 and 2 for guests without a UM uniqname

3. Once registered complete BLS025W (General Lab Safety).

4. Be aware that this test can be very long – if you are unfamiliar with lab safety and watch each segment of the video all the way through, it is approximately 4 hours long.

Battery Lab Industrial User Pricing

The Battery Lab is focused on helping customers scale up battery innovations. We rent out the pilot scale facility by the day to customers looking to build 18650 and pouch cell batteries (72 mm x 110 mm, stack height up to 10 mm). Customers are assisted in using the equipment by the Battery Lab staff. Pricing for renting the pilot-scale battery equipment is $3,000/day. On average, building a batch of 25 18650 or pouch cells will take up to a week in the lab, at a total cost of $15,000 plus consumables.

Note: The cost of renting the pilot-scale battery equipment will increase to $3,500/day starting January 2019.
