Sure, electrified isn't necessarily fully electric, but depending on how the car is used, it can still make a big difference. And until batteries become significantly lighter and smaller, I don't think that fully electric is the right option for everyone. If you make one long trip a year (beyond even the range of even a Tesla/Bolt), and the rest of the year your daily mileage is 20-30 miles, a PHEV may be the logical choice. And for people who are concerned that EVs have insufficient range, PHEVs make great transition cars. After driving one for a while, many people discover that they use the petrol engine much less than expected, and go for an all-electric with better range next time around.
On batteries, I'm not sure that manufacturing your own ones is that important. There are advantages to both approaches. Buying third party batteries is more flexible in terms of scaling up and down - you just buy more or fewer batteries, depending on demand, but obviously at a time like now, with global shortages of EV batteries, having your own production is an advantage. Probably that situation won't last for long, though.
Either way, I just think it's amazing the number of new electrified models being announced recently, whether fully EV, PHEV or hybrid. It will take a year or two until most of them hit our streets, but by 2020 there should be far more EVs available than at present. Which has to be a good thing.
