NMP is use since 25 years for cathode coating worldwide ... including Germany. Water is also investigated as a replacement but it is not that easy to replace NMP. Battery industry knows how to use it safely as industry knows to use safely many and many toxic chemicals. Dreaming that Samsung, LG, Sony, Panasonic, BYD, Wanxiang, Saft, GS Yuasa and many others are wrong and suddenly needs technology of a tiny company like Electrovaya is funny and anyway Electrovaya patents are old. That do not means there is no interest in Electrovaya stock, small cap could surge nicely in hype market like lithium ion. Just hope plan aquisition make sense and that they will provide update soon, as they made first PR deal should be almost close.
