Improving Lithium Ion Battery Wickablility with Plasma Treatment

Manufacturers of lithium ion batteries have found significant benefits to encorporating surface treatment into their fabrication operations. Surface treatment offers real opportunities for in-line continuous improvements in surface wettability and cleanliness as dry surface treatment processes.

Some of the key benefits for this include the following:
  • Continuous, roll-to-roll process
  • Significantly lower production floor footprint
  • Elimination of chemical primers
  • Significantly lower capital cost
  • No VOCs or chemical effluent disposal costs
  • No water supply costs

Enercon’s Plasma 3™ technology enhances surface properties of separator and foil components of lithium ion batteries resulting in increased hydrophilicity and wickability improving the efficiency of the battery cell.

A modified separator membranes utilizing Plasma3™ surface modification shows improved wettability and electrolyte retention. Plasma treatment of foils leads to high surface tension and cleaning of surface contaminations to improve interfacial adhesion with coatings.

This results in surface cleaning affect which reduces organic contamination on the surface in the form of residues, anti-oxidants, carbon residues and other organic compounds. Using Plasma3™ as an integrated roll‐to‐roll or continuous production line process for manufacturing power generating materials can be key to developing continuous, in‐line production processes to create inexpensive and flexible item‐level power sources.

By implimenting these technologies there is a considerable cost-reduction in lithium-ion battery fabrication can be achieved and ehnhancement of the battery performance enhanced.
