I hope people realize that finding new and improving battery technology is the #1 thing being worked on by companies today. Everyone knows that Li-Ion is a limited resource, heavy, and doesn't hold much power. EV's are sill a proof of concept, and they are taking off, so the concept works. New battery technology includes Sodium Ion, fuel cell, graphene, and many more. With my limited knowledge, even I know this is the future. There are 2 things manufactures are trying to perfect, lowering the cost, and longer battery life = more power for size and weight. Even the charging systems are in their infancy. They are building more and more each day. Our Government is spending billions to add more charging stations and replace old ones. This will only get more prevalent as more and more people own EV's. Right now they are grocery getters. In my lifetime and many who are on this thread, they will be here and they will replace most common vehicles. Just look at every car manufacturer has an EV and even more are sprouting up such as Tesla and Rivian. As for the semi truck revolution, they are here and will be replacing long haul trucks, along with autonomous vehicles. It's right around the corner. Technology is evolving faster than I can write this message...

You seem to think battery's are new? Battery's and battery powered vehicles have been around since the 1800's. They even pre-date ICE vehicles.

In reality scientists have been working on improving the battery for over a 100 years.

Hell, even LI battery's have been around since the mid 70's to early 80's. Even with the best of technology we have out today I still have to plug in my phone in every night to charge. And my phone uses very little energy compared to a big energy user like a truck. All of those battery's you mentioned have their pluses and minuses. Some are energy density, some are cost, some are they just fail over a short period of time.

As far as the Semi goes, you're in dream land, and here is why. In a few words it's "energy density"......or lack there of.

Let me put up a picture for you that may bring it a little bit better into focus for you:


See the problem now?

It's really easy to compare electric to gas or electric to diesel. It's not magic. We know how much energy in in a KWH or electricity and we know how much energy is in a gallon of diesel. To get the same amount of energy out of diesel you need the same amount of power electricity. It's really that simple.

I do not understand that graphic at all. What exactly do you mean by "energy density" or are you referring to "power density"?

Diesel burns to create heat which is used for power. Lithium is used as a material in a storage system for electricity (battery) and does not generate any power of its own. Why don't you compare the energy density of diesel to say, lead? Or sulfuric acid?

And batteries can be recharged. Can't do that with liquid fuel.
