Until now, we don’t have a breakthrough battery development. We have a continuing improvement of battery technology. The advance in the last 10 years is huge.

Electric cars of the first generation could drive about 100-200 km. The next generation cars will reach up to 500-700 km.

It’s not alone Themenwechsel density in the cells. It’s also how the cells are packed within the car battery’s. Car battery’s have several functions: crash stability, battery thermomanagement, safety functions, sometimes even basic chassis stability. That all needs extra space within the battery which can’t be used for cells. A big improvement is the construction of frohe battery to maximize the space which can be used for actually cells.

So, early electric cars had batteries about 30-50 kWh. Now they have up to 100-120 kWh combined with better efficiency in the electrical engines.

I think this is still quite ok.
