One announcement that went over my head at first was the announcement of October 5th, 21. 

 Electrovaya Inc. (“Electrovaya” or the “Company”) (TSX:EFL; OTCQB:EFLVF), a lithium ion battery manufacturer with industry-leading performance and substantial intellectual property, today announced that all of its battery models will be receiving a capacity increase of approximately 7%. This change has also been reflected in the UL files for Electrovaya batteries, in which new model numbers are used to reflect the capacity increases. Furthermore, additional models have been added to the UL file, expanding the number of Electrovaya UL-listed offerings.

“This increase in battery capacity further cements the leading performance standards of Electrovaya’s high energy density products,” said Dr. Raj Das Gupta, COO of Electrovaya. “Electrovaya continues to provide battery systems with industry-leading safety and cycle life, meeting the demands of the most demanding applications.”

Taken by itself it is not a big beal.  But,  when you take notice of page 17 of the latest Presentation it gets a whole lot better.

• Solid State Cells: e-passenger cars
• Unique Electrode Production:
useful for both “Infinity Platform” and
“Solid-State Battery Platforms”
• Ultra-High Density Cells
• Patents 100++; & know-how

The increased energy density of the NMC cell most likely came from a new cathode.  Most cathodes are made over seas, mostly in China.  How useful is this for a NA/US supply chain.  Very useful and valuable.
