New uses for Lithium Primary batteries appear every day in areas as diverse as industrial electronics, information technology, medical care, and military aerospace. H&V’s industry-leading Lithium Primary separators are engineered to be stable in non-aqueous electrolyte environments and are optimized for both strength and battery performance.

  • H&V separators can sustain the battery temperatures in excess of 400°C.
  • Our separators provide optimum smoothness and consistency of surface for efficient battery assembly in both button cell and spiral wound processes.

H&V Lithium Primary separators deliver critical separator consistency.

Additional benefits include:

  • High purity and stability in non-aqueous electrolyte environments.
  • Stable in high-heat applications.
  • High Porosity to maximize electrolyte volume.
  • Good physical strength for battery assembly.
  • Smooth surfaces for further optimization in battery processing.
  • Tight thickness and basis weight control for processing.

Our most popular grades, BG03013 and BGO4013, are differentiated by weight and thickness and are stable in temperatures approaching 300°F. For higher heat applications, we recommend BG03015, a binder-free separator.
