According to the company, Symmetrix separators increase the life and high-power capacity of lithium-ion batteries, minimize waste heat in batteries, increasing a cell’s capacity and allowing it to operate at safe temperatures with few external cooling requirements.
The company added that the separators also enable fast battery charging with less heat build-up and facilitate battery function in low temperature operating environments.
Yozo Shimomura, general manager of precise fabricated products department at Chisso, said: “Our companies share a mutual goal of dramatically improving the safety, durability, performance and price of lithium-ion batteries for electric and hybrid-electric vehicles.”
Tim Feaver, CEO of Porous Power, said: “Automotive battery manufacturers want a safer alternative to traditional polyolefin separators, which can melt and cause thermal runaway, and potentially fire, at relatively low temperatures.
“Undesirable voltage and temperature fluctuations occur much less frequently in cells using Symmetrix separators, even under conditions of abusive overcharge and overheating.”
