Technology Lightning Talk - Achieving Valid Cell Self-Discharge Measurements: How External influences impacts Results

Edward Brorein  (Application Engineer, Keysight Technologies)

Location: USA

Date: Wednesday, November 11

Time: 1:15pm - 1:30pm

Track: Battery Design & Manufacturing

Format: Technology Lightning Talk

Audience Level: All

Li-Ion cells all have self-discharge. Some is normal but excess self-discharge indicates potentially catastrophic problems, dictating all cells must be screened in manufacturing. However, the challenge here is self-discharge is far from being relatively fixed and constant. It varies greatly with rest time since charging or discharging, temperature changes, and state of charge. This causes results from lot-to-lot, or even within a lot, to be grossly inconsistent, hindering the ability to effectively screen out cells with excess self-discharge. In this presentation, Keysight will share data quantifying external influences on self-discharge measurements, providing key insights on achieving consistently valid results for more effective screening of cells in manufacturing.


Attendees will gain greater appreciation of how various external factors impact their cell self-discharge measurements, to what degree they're impacted, and how to account for them, through the test data and analysis shared from this presentation.

Intended Audience

Engineers and scientists responsible for formation and electrical test processes and yields for LiIon cells in manufacturing, will benefit greatly from attending this presentation.
