Fill and Flow for Thermal Regulation

Enhanced Safety, Improved Performance,
Higher Cost Efficiency

Thermal Regulation for
Every Industry

Thermal management requires a strategic design approach, specifically for passive systems, which requires a solution to have:

  • A minimal impact on the overall weight of the battery system
  • High heat absorption properties from tailorable temperature ranges

Fill and Flow provides these critical factors for Li-ion batteries in one all-encompassing solution designed specifically for your application.

How the Fill and Flow Technology Works

Our thermal regulation solution material provides passive energy absorption, thermal
homogeneity, and performance improvement for your product requirements.

Fill & Flow is designed to easily fill enclosed and small-cavity systems by completely flowing
around, encompassing, and contacting all surfaces of fully enclosed cells and packs.
