 The key to achieving a renewable alternative to fossil fuels for transportation is the development of compact, lightweight, high-efficiency lithium-ion batteries that can perform for years through thousands of charging cycles.
Extrusion Dies Industries, LLC (EDI) now supplies die systems that produce the exceedingly precise coating and film layers required for the multilayer structures within such batteries that actually do the job of generating electrical power. EDI works on process development with manufacturers of lithium-ion battery components at their own facilities and in the film and coating process laboratories at EDI's new Technology Center in Chippewa Falls. Among technologies perfected by EDI is a system for simultaneously applying anode or cathode coatings to both sides of a substrate, enabling electrode manufacturers to increase productivity by using a flotation dryer to dry both sides at the same time. ''Because EDI specializes in high-precision flat die systems for films and coatings, we see ourselves as providers of enabling technologies for manufacturers seeking to increase battery efficiency, reduce weight and cost, and ensure reliability,'' said John A. Ulcej, president. ''EDI brings years of experience in developing film and coating die systems for batteries, as well as for other critical multilayer electronic applications like flat panel displays and solar panels.''
