Degussa, a global leader in the field of specialty chemicals, will showcase its work on lithium-ion batteries, hybrid vehicles and lightweight construction at the upcoming SAE 2007 World Congress in Detroit.
Degussa began volume production of electrodes for large-format lithium-ion batteries at the Li-Tech GmbH (SK Group) site in Germany in the fourth quarter of 2006. (Earlier post.) In Detroit, the company will exhibit a Honda Civic hybrid equipped with a li-ion battery made of Degussa electrodes with some 40,000 kilometers (24,855 miles) of on-road testing.
Degussa also offers a ceramic membrane separator—SEPARION—which consists of a flexible substrate, normally a non-woven polymer, coated with a porous ceramic layer. The pore size can be selectively set by an appropriate choice of ceramic coating material. According to Degussa, the ceramic properties of the separator make it more temperature-stable than conventional polymer separators used in lithium-ion polymer batteries, and therefore contribute towards preventing short circuits in the battery.
The company will also present adhesive solutions to replace welding, both in the chassis and the superstructure. Degussa says that every additional kilogram of the special adhesive makes the car 25 kilograms lighter. Degussa supplies silanes for the adhesives.
