Toyota’s Redesigned Aqua uses a new Bipolar Nickel-Hydrogen Battery

The world named Prius C (as known in the US) has a better 1.5L engine and a new bipolar NiH2 battery. Unusual to call it Nickel Hydrogen and not NiMH. Makes me think it’s actually using gaseous hydrogen like the NiH2 batteries I worked on in the 90’s. The brunt of the story is they can make a Bipolar Nickel Hydrogen battery in a smaller denser space as well as lower the internal resistance (read: less heat generation while charging and especially discharging) than the current NiMH battery. Maybe the current hybrids using Nickel based batteries have some life left in them.

Just wondering if Toyota has started calling all their NiMH batteries Nickel Hydrogen? Or is this a plan to test using bipolar design for their eventual solid state batteries to get more current out of them?
