(Dec. 4, 2014) – Arnold Magnetic Technologies introduced today its BESThin line of thin and ultra-thin metals for efficient battery and energy storage designs. The BESThin line, which includes nickel, aluminum and copper, enables thinner substrates to be used in [battery and energy storage](http://www.arnoldmagnetics.com/Precision-Thin-Metals/Markets/Battery-Market.aspx) technologies. As the push for new battery performance materials increases, titanium and stainless steel are also being considered. These thin substrates improve storage capacity by allowing for greater energy density in a smaller system. In addition to thinness, Arnold is able to improve material performance through fine-tuned grain size and grain structure and uniform surface roughness. These optimizations allow for precise deposition of electrode materials onto the substrate. Advances in battery technology hold particular promise for the automotive and transportation industries. Smaller, lighter, and more power dense designs will enable vehicles to meet stricter energy standards. Other applications that benefit from thin metal substrates include mobile devices, advanced fuel cells, and photovoltaic (PV) solar cells. “Thin and ultra-thin metals play an important role in today’s battery and supercapacitor technologies,” said Ted Baker, General Manager of Arnold’s Precision Thin Metals (PTM) division. “We’re working with customers to overcome the challenges and limitations of each technology, in order to achieve more efficient electrification of their machines.” Arnold is an active member of The New York Battery and Energy Storage Technology Consortium (NYBEST™) which is an industry-led, private-public coalition of corporate, entrepreneurial, academic and government partners focused on developing world-class battery and energy storage solutions in New York State.
