Those of you who
are faithful followers of this blog (all 7 of you) should know that I come from
the school of thought that you always need a better battery. I even have a law for this, which I call the
zeroth law of batteries and it states:
The performance of any battery will
fall (just) short of
our expectations irrespective of the complexity of the device it is
powering.
This is true for
our cell phones and Roomba’s. And true
for electric cars and plug-in cars.
That is, unless
you have low expectations.
The world has
seen some dramatic changes in battery technology over the last 20 years, ever
since the Li-ion battery became commercial.
For one, the smartphone revolution would not have occurred if not for
the batteries. A lot of improvements are
still possible with lithium-ion, and we project that battery energy densities
will double when we succeed in controlling more energetic anode and cathode
materials.
But what happens
after that? At the pace at which my
smartphone is evolving, with Retina Display screens, 4G networks, and movies
playing off of the air, it’s hard to see a doubling in energy being
enough.
Question then
is: What is after Li-ion batteries? And
is there something out there?
The answer is:
Yes. But getting there is not going to
be easy.
I wrote about
this in two blog posts titled “A brief history of batteries- Part 1” and “Part 2”. These two posts describe possible battery
chemistries of the future and make the point that to succeed we really need to
understand the past. And it is written
in the style of the movie “Pulp Fiction”. Can any battery textbook beat that?
I would suggest
that you read this blog post first.
Once you do that,
you will want to know: So what is the progress in these chemistries in the two
years that have elapsed since the blog post?
You will get an
answer to this question if you show up at the Claremont Hotel in Berkeley CA
between June 5-7, 2012 (a month from today)*.
This will be the venue of the 5th in a series of symposia
titled “Beyond Li-ion”. In a 2 ½ day period
various researchers, who are at the forefront of this field, will tell you what
the latest trends are.
It is an
impressive speaker list, which you can see here.
As a bonus, you
will get to come to Berkeley Lab to see our Lab facilities. More importantly, you may (I should
emphasize the fact that this is a real possibility) actually get to shake my
hand!
To attend you
will need to register, which you can do here.
Hope to see you all
(and I mean all 7 of you) there.

p.s. Please don’t ask me to waive your
registration fee. Being a co-organizer
means that I write blog posts to promote the meeting. It does not mean that I
can come up with the cash to pay for your meals.
