PlasmaTalk: How to Reliably Improve Cell Wetting Rates and Adhesive Bonds in Battery Production

Date: December 07th, 2021

Time Slots (UTC): 6 am, 9 am, 4 pm

Duration: 40 - 60 min

Language: English

Following the trends of modern mobility, the requirements for EV batteries are increasing both in terms of dimensioning and packing density. This means, battery cells are currently being built larger and larger, and the trend within the cell is toward thicker and denser layers of active material.

To achieve uniform and consistent wetting throughout the battery cell - including in the center - the wetting behavior must be optimal. Openair-Plasma® can be used to improve the wetting behavior of the active material. Reliable wetting fully exploits the performance potential of the battery in question. This was investigated in the publicly funded project “SurfaLIB – Advanced lithium-ion batteries by modification of the electrode surfaces”.

How this works is explained by Lukas Buske, head of plasma applications at Plasmatreat Germany, in this PlasmaTalk. Both Krüss' Mobile Surface Analyzer (MSA) and the K100 Force Tensiometer are used to measure the results, which reliably map wetting rates even with fast-absorbing liquids. Dr. Daniel Frese, Application Market Manager at KRÜSS Germany, will explain and interpret the measurement results.

After participating in this PlasmaTalk you will know more about:

  • Openair-Plasma® - what does it do on active material?
  • How reliable wetting fully exploits the performance potential of the respective battery
  • How Krüss provides the necessary measurements to document these effects
  • Outlook: Increasing energy density through Openair-Plasma® treatment for more powerful batteries without increasing size

This no-charge PlasmaTalk is aimed at research, development and quality control personnel as well as designers, process engineers and operators of production equipment in industrial processes.

The PlasmaTalk will run for appr. 40 - 60 min. including FAQs. If you have a specific problem or question, please send your question in advance to academy@plasmatreat.com and we will be happy to include it into the program.
