The big milestone is the cycle life for -- and this solid-state battery, the energy density is very high and it's -- or the projected energy density is high. So, it's really perfect for the electric passenger cars, which needs low cost, low initial costs. And typically, these passenger cars, electric passenger cars, need certain cycle life. And this has been difficult to meet with other solid-state cells and batteries. And we will give our progress, and the progress so far is good, so we will give it more fulsome information on the progress shortly as the result comes out.

There appears to be a car manufacturer in talks with Electrovaya concerning using this battery if it passes muster.  Sounds like to me there is a possibility that EFL will be a $5 stock before the Summer is out.......That would also mean a manufacturing plant construction announcement.....
