Daramic showcases at the 2018 BCI Convention in Tucson, AZ, USA

May 7th, 2018

Charlotte, NC - Daramic, LLC (http://www.daramic .com), the world’s leading manufacturer of high performance polyethylene (PE) battery separators for lead-acid batteries, Daramic unveiled several new separator designs developed specifically for the start-stop (enhanced flooded batteries) and deep cycle batteries and engaged with the industry through multiple customer and partner meetings and booth expo at BCI Convention & Power Mart, which is North America’s largest lead-acid battery tradeshow, in Tucson, AZ April 29- May 1, 2018. The three day conference featured presentations highlighting the state of the industry, trends, and new product developments.

Developed to support operations in partial state of charge, utilizing the separator as a carbon carrier, dynamic charge acceptance is improved. Whear says, “We propose to use the separator as a carrier for the carbon that will come in contact with the negative electrode. This is achieved by coating the side of the separator facing the negative electrode with a thin, porous layer of the effective carbon of choice. ”Testing has confirmed at the cell and battery level that charge acceptance has been improved. In addition to the dynamic charge acceptance, special additives are employed to the separator to lower water loss, a noted side effect of adding carbon directly to the active material.


As the inventor of the polyethylene (PE) battery separator, Daramic is now reinventing its technology to help innovate lead acid battery technology. For the third consecutive year since it was initiated in 2016, Daramic was selected as a finalist for the Sally Breidegam Miksiewicz Innovation Award.

  • 2016: DuraLife (commercially available) demonstrated reduced grid corrosion and enhancement of life for SLI batteries
  • 2017: EFS and RipTide (commercially available) was developed to improve Enhanced Flooded Battery power and acid stratification
  • 2018: Daramic Carbon Coated Separator Technology (in development) showcases the separators ability to further improve dynamic charge acceptance for start-stop, motive power and renewable energy applications, while avoiding the negative side effects, like waterloss, found in other carbon based solutions.bci_2018.png

Daramic's clear innovation leadership shows its willingness to support technical advancement of lead acid battery technology.
