I briefly had them confused with Maxell, the makers of the cassette tapes used for your really _important_ mix tapes, and the floppy disks for all your cheap, cracked video games. Yes, Maxell does make batteries. (Well, they don’t make many floppies anymore.)
This is interesting: it confirms that yes, Tesla sees the writing on the wall vis-a-vis the expiration date for Lithium battery-technology.
Solid state batteries are coming, and the price of the current high-cap batts has been rising and will continue to rise, putting constraints on growth for both the vehicles (not just Tesla's) and the Tesla Powerwall products.
Heh, and yeah, Maxell was my go-to for _important_ mix tapes, and that was back before I'd ever heard the expression "mix tape". ;^)
Yes, it’s the end for Lithium. They project 10% average performance improvement year over year on average. Cobalt seems to be the Achilles heel right now.
