solid state, li-fe, li-po. all suffer from poor performance in cold weather. try taking your electric leaf blower in the below freezing temp and run it, i bet you get 5 minutes of full power if that.
to give you an example of how far off those techs are, li-po batteries used in tesla today were first commercially available in 92'. the first tesla cam out in 2005 and they are still tweaking the tech to this day.
glass - no commercial products yet, one company has committed to try it in 2020
Silicon - farthest along, partially implemented in tesla's newest batteries.
solid state - only found in things like pace makers (uber expensive device). low temps make this a problematic solution.
i still maintain 20 years before consumer market is dominated by EV only. Look at trains, diesel electric trains replaced steam coal fired trains in the mid-1930's. you get the best of both worlds, constant torque and long range of gas. cars are only 66 years late to the game(prius, first popular hybrid).
i would also note that I dont want to back my EV truck in the lake to unload/load by fishing boat.....
