Toyota's Lentz sees car sales stabilizing, EVs languishing

Thank you AGR sir. Lots of research going on with battery chemistry as well as production process technology. That should reduce battery costs.

Toyota Research Institute is working with University of Houston on magnesium batteries with chloride free electrolytes. Magnesium is more abundant and less expensive than lithium. https://www.sciencedirect.com/science/article/pii/S2542435118305713?via%3Dihub

Magnesium batteries could offer high energy density and safety due to the non-dendritic Mg metal anode. However, Mg2+ ingress into and diffusion within cathode materials are kinetically sluggish. It is therefore intriguing that recently organic cathodes were shown to deliver high energy and power even at room temperature.

Herein we reveal that previous organic cathodes likely all operated on a MgCl-storage chemistry sustained by a large amount of electrolyte that significantly reduces cell energy. We then demonstrate Mg batteries featuring a Mg2+-storage chemistry using quinone polymer cathodes, chloride-free electrolytes, and a Mg metal anode.

Under lean electrolyte conditions, the Mg2+-storing organic cathodes deliver the same energy while using ~10% of the amount of electrolyte needed for the MgCl-based counterparts. The observed specific energy (up to 243 Whr kg-1), power (up to 3.4 kW kg-1), and cycling stability (up to 87% at 2,500 cycles) of Mg-storage cells consolidate organic polymers as promising cathodes for high-energy Mg batteries."

I see Lentz's comments as self serving for 2 reasons: Toyota plan to continue sales in that segment, therefore it behooves him to toe the company line and predict adequate sales levels going forward. The other reason is Toyota seem to be suspiciously absent in BEV development, so one might infer that Toyota have not strategically bought into the BEV hoopla quite yet, and perhaps plan to continue down the path of hybrids and fuel cell development.

I'm so glad you brought up that emerging research, maybe it time for  a new player to enter the game and make Lithium redundant..
