Register for David Theuerkauf’s September 20 seminar
The ECS Detroit Section invites you to an in-person seminar with David Theuerkauf, Technical Sales Specialist, AVL North America, at 1800h on September 20, 2023, at Mercedes-Benz R&D North America.
Abstract
In constructed lithium ion batteries, only voltage, current, and temperature can be measured. This leads to difficulty making in situ analysis of electrochemical properties. Measuring and sourcing current at a high level of quality, 0.005% of full scale range, is considered ultra-high precision coulometry. Analysis of ultra-high precision coulometry metrics can be made by running cells at a slow 16-hour charge and discharge rate, with stable environmental control. These metrics can be used to compare degradation rates and anticipated rollover failure, quickly compare different potential chemistries or electrolytes, or detect lithium plating. (more…)
