Anyone knowledgeable on energy storage technology who gives advice on
investing in, say, copper, might be wondering about future advances in
battery technology.
No one can predict names, dates or improvements but time-profiles of
the most plausible developments may be useful.
Fix cost/watt-hr and plot energy density vs time.
or
Fix efficiency and plot cost-watt-hr vs. time.
or
and so on.

Since the first battery prototype developed in the late 19th century,
the basic battery design has not changed significantly; only the
chemistries have evolved. Introduction of new chemistry composition,
such as lithium ion, has improved battery life but has not solved the
demand. In fact, for most batteries, it is believed that they have been
optimized to reach their maximum output and lifespan. This especially
applies to primary batteries and nickel cadmium (NiCd) batteries.
Conventional batteries are falling behind the demand for more battery
"juice". It does not appear, however, that the lithium-ion battery has
reached its maximum charge limit. Recent announcements by Sony and
Matsushita (which makes Panasonic batteries) claim...

Getting the grid entirely on solar and wind seems somewhat less
daunting now.
If it actually cycles 40K times then it can cost an order of magnitude
more/charge and still be competitive for some applications, stationary
energy storage, semi-trolly buses and tractors.
Even sharing a commuter vehicle with with a quarter ton battery that
needs to be recharged every 200 miles would be preferable to many
solutions.

6 years of research. 10,000 prototypes. Production capacity of 100,000
batteries per month.
You'd think they might have a product one of these years.

Sounds like Edison's light bulb effort.
Of course, if the technology is twice as challenging as getting a
filament white hot then they are only half way there.
