I agree.  Electrovaya is one of the very few battery companies that has shown a profit.  I don;t know of any others, but but as sure as I say the only one, someone will point out one.  Anyway when trying to decide on which battery company to invest in, I looked at the technology.  Electrovaya (in my opinion) has the best battery.  The safeest.  The longest cycly life with exceptionally high energy density.  Sealed my choice on Electrovaya.
