Deal closing is April but 1st info on acquisition is november 2014.
Anyway, Evonik was planning divestment of Litarion in 2013 so assume begin to explore new market for separion since months, and previous to be exclusive to Daimler, Evonik have made also great efforts to promote Separion with deal with Enax for example in 2005 (JV in 2005 in China http://www.greencarcongress.com/2005/06/degussa_and_ena.html). Not very successfull at this time but ceramic coated separators is much more hot now than in 2005 as tend to become a standard for many advanced/high-energy density lithium ion batteries.
Sales to China concludes by Evonik representative in China, so more an Evonik deal than Electrovaya but confirms Litarion/Separion acquisition good deal for Electrovaya on technical and team level.
