Charles Zhang was marketing at Evonik and assume now Separion/Electrovaya.
Evonik plan divestment since long, in 2013 Daimler/Evonik were expecting above 1Bds offer for all activities at Kamenz but no big name interested (LG offer 1 euros).
Time to enter in discussion, providing sample, testing them, negociating/signing contract could easily take 1 year, so assume process has been launched prior.
Anyway in both case a good news, but need more positive newsflow, nice bump from 30 cents to 1$ following acquisition but SP already back to 67 cents low today, no news no up move in stock.
