Just because something takes energy to make doesn't make it a fuel source. It takes energy to make fresh water from salt water, water is not a fuel.
Something is a fuel if it has positive potential energy that can be practically released and used for work or heat energy.
Wood is a fuel because it can be harvested then burned to release heat. Gas is a fuel.
The energy to make a battery isn't part of the energy that is used to turn a motor. The energy to make a battery is like the energy to manufacture gas, chop down trees, or build a nuclear plant. The energy to manufacture gas isn't what makes gas a fuel, the chemical energy already in the chemical bonds is what makes gas a fuel.

Batteries need to then be charged yes, using an actual fuel. The electricity has to come from burning coal or similar (chemical energy), or a nuclear plant or solar (nuclear energy).
And batteries aren't always discarded, they're recycled in the case of the Tesla.

Batteries aren't a fuel, they aren't a source of potential energy that can be harvested with less energy than they produce. From the point of view of the wheels of the car, I guess you could say a battery is a fuel since the wheels don't care where the energy comes from, but your point seems to be to look at the entire thing.
And I asked a question, what fuel source is better? If you claim there are better, actually listing them would be helpful.

Evidence?
And again what do you propose that will be superior?

You have to take energy away from water to make it into ice, not add it.
What equation are you talking about?
Where does the energy in a battery come from?
