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?


The cells my wife works on are 1.5 volts and they cost $10,000 per cell.
There may be 40 cells in a pack.

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.


The energy we get out of a gallon of gasoline has improved over time
too.


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 problem is that the internal combustion engines are more
environmentally friendly that EV's or Hybrids.
