What advances in batteries have we made in the last 100 years?

You put energy in and you take energy out.

That's what batteries do of course - store energy for use at a later
time. How do you propose to advance that?

Energy stored per pound has advanced a lot. If you don't believe
that, take a look at the latest generation of cordless tools or laptop
computers.

Being able to store energy at a reasonable cost and weight is key to
making electric vehicles practical. Although the Volt is not yet the
ideal electric car, it is a step forward. Internal combustion
engines started off slowly also. Take a look at the automotive
engines of 100 years ago vs what we have today.

The Tesla is quite the technological car though!

The Tesla is a fine example of what you can do if cost is no object.
Since they are in a high end specialty market there is not a lot of
pressure to lower the cost but it's nice to see an example of what is
doable.
