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.

But again, as the technology surfaces, cost goes down.

You would have thought that withe 100 years of effort you wouldn't run
into the bricking problem.
