There are a lot more interesting comments in the comment section similar to the one above.. and found in the article with the following link:

 OK, addressing the Tesla acquisition of Maxwell Technologies is the following comment:

 "Does the deal make sense? Yes, says Cowen analyst Jeffrey Osborne:

 We see the deal offering three layers of synergies for Tesla relative to other would be-acquirers. Namely, applications in automotive, grid applications combining lithium ion batteries and ultracapacitors for grid stabilization and ancillary services, and opportunities for Tesla to improve energy density, and thus range, with Maxwell’s dry electrode capability and graphite expertise.

 Ravi Manghani, director of energy storage at Wood Mackenzie, told Quartz.com that it’s the dry electrode battery technology that Tesla wants, “the early results of which look promising.”

 Just some food for thought, Pavel, on the Tesla-Maxwell situation and about Jeff Dahn.  Okiedo
