Why I work at a National Lab.

Over the years, one question that keeps popping up is why I decided to work for a National Lab, as opposed to a university or industry.  My first answer to this question, which is “because John Travolta once told me that without a job, residence or legal tender, I will be a bum” does not seem to lead to satisfaction.  So, here is the alternate answer.

When I first came to a National Lab, I really had no idea what a Lab did versus these other entities.  I had heard the origin story (the Manhattan project), seen the big, unique, expensive facilities (the synchrotron sources and the nano-centers) and knew the names of the many of the scientists in the complex as leaders in their field.  But it took a few years of being at a Lab (after I got past the “do not become a bum” phase) for me to really understand their critical role in scientific innovation.

At its core, scientific discovery has become hard.  The days of the inventor who tinkered on something in the garage and discovered the next big battery breakthrough are long gone, unless you are developing battery apps.  The “low hanging fruits” have all been picked.  The world still needs new discoveries leading to better technologies; so we have had to, and will continue to, go higher and higher up the proverbial tree.  

National Labs were/are built to satisfy this need.  In my opinion there are three aspects to a national lab, the first two being:  (i) take a bunch of smart scientists and engineers from diverse disciples who are willing to dedicate their life, working as a team, to solve a problem, and (ii) provide them with the means to build unique facilities (think big $$) and capabilities (think brains), unlike any other in the world.  Do this long enough that this combination will yield new breakthroughs, new insights, Nobel prizes, and the rest of the good stuff.  And out of this mix emerges the thought leaders who define the next phase of innovation and set the path for what will be the future. 

In the age when the great industrial research labs are all long gone, this role takes on an even greater importance.  

But there is a third aspect to a National Lab which, in my opinion, is equally important.  We are taxpayer funded and have an obligation to help the taxpayer in whatever way we can.  Which means that it is not enough to develop (i) and (ii) and then keep it behind closed doors, with an insular approach to problem solving.  Rather, our mandate is to use said facilities and capabilities to help the broader community gain further knowledge, aid in their quest to discover new things, win their Nobel prizes, and serve as a means of enabling new products that will drive the next big market. 

But there is lack of understanding among the larger science and technology community about this aspect of Labs.  This is especially true for companies.  For one, we at the Labs do not do a great job of explaining what we have and the breadth of our capabilities.  There is a translation problem between a Lab scientist explaining a new technique and a company scientist understanding how that technique can solve a battery problem. 

And then there is confusion about the ways to even work with the labs.  Companies often don’t realize that they there are well-established mechanisms to work with Labs, that protection of IP and confidentiality are built into these relationships, and that the Labs actually WANT companies to work with them. 

A decade ago, during the cleantech boom, I was able to witness this issue firsthand.  As companies started investing more into commercializing new technologies, the translation problem became an obstracle in leveraging the assets in the National Labs to effectively move forward.  Since those days, I have been passionate about finding ways to solve this problem. 

In June 14th, we are embarking on another part of the journey to solve the translation problem with, what we are calling, “Battery Industry Day at Argonne”.  On that day, we will open up the door to industry (and others) to show you what we have, both the people and the facilities, tell you a bit about what we do, hear from you on what issues you face, and introduce you to the various mechanisms we have to work with outside entities. 

We will talk about three areas where Argonne has deep expertise: high-energy batteries used in everything from cell phones to EVs, stationary storage and its integration with the grid, and batteries for our national security needs.

You can read a bit more about the day and register at this site.  Ping me with any questions.

All you need to know about batteries: in a dozen tweets.

I've been told that my blog posts are very long.  I have been known to retort that no one reads anything anymore.  After a few years of going back and forth on this I have come to the conclusion that if you can't best them, join them.  

Research (an euphemism for "made up") suggests that the human brain can't take more than 140 characters.  So here goes.  A summary of batteries in a dozen bite-sized tweets: 

Guess which battery will power most phones, EVs, and home solar in 2025?  A lithium battery. Yes. Really. Good luck new chemistries.

A battery fire is a feature…in Antarctica. For the rest, so wish we had new chemistries.  Water, where art thou? Hate flammable electrolytes.

Lead-acid (yes, that old dog), will destroy Li-ion for grid storage. Oh ya… there is that sulfation thing to solve. 

The 2017 Li-ion battery is not your grandfathers one.  It is oh, so different on the inside. Don’t judge a book by its cover.

Is there a solid-state battery in your EV future?  Not unless you are less than 50 years old (assumption: life expectancy=70). I made it.

EV battery roadmap: High voltage then silicon, then Li metal, sulfur, (oxygen?), Mg (Al?). After that? Aliens tech. Or maybe fluorine.  

Grid battery roadmap: Li-ion or lead-acid or flow or sodium or Zinc or... Who knows. Confused? So is everyone else. Except the aliens.

Hear about an amazing breakthrough in batteries? Safely ignore it. The inventors did when they violated a few laws of nature. 

All battery companies will claim to drive cost to less than $100/kWh sometime in the future. Even if they make the battery out of solid gold.  

Performance of any battery will fall (just) short of expectations irrespective of the complexity of the device it is powering.

Pull the plug. Your battery will thank you.  And don’t use the wrong rules for the wrong battery. Memory effect is so 1995.   

It takes 10 years and $250M to start a battery company. Unless you are in China. Then it takes 1 year and $50M. Gotta love incentives.

Everything you need to know about batteries: In 600 words or less.

Last week a person I know wanted to learn more about batteries.  I was a bit surprised that this person was not already leaning on, what I consider, the ultimate resource for all things batteries: TWiB.  

Upon further reflection and some much-needed soothing of my bruised ego, I have had an epiphany.  After more than 50 posts and 42,000 words*, covering topics ranging from potato batteries, to the rules that govern batteries, to the state of the battery market, I can see why one would be confused.  I guess it is like trying to figure out where in the Mahabharata one encounters ethical dilemma’s (hint: There are way too many to just look up in any one page).  What we need is a cheat sheet: a Douglas Adams synthesis of the vastness of the universe, if you will. 

So, I decided to make it simple and guide you thru my numerous blog posts.  Hopefully this guide will help you realize that TWiB has everything you need to know about batteries, and a few things you did not even know you need to know. 

Want to know about the history of batteries, the many kinds of batteries, and how we innovate in batteries?  Check out my posts on the History of Batteries.  Read both Part 1 and Part 2.  Frankly, even if you think you know a lot about batteries, you can read these two posts. 

Want to know how to maintain your car battery, your old Roomba, and/or your laptop?  Did you know each of those devices have a different kind of battery?  Learn more. 

Have you always wondered what the highest energy density battery ever made was?  Or the one with the longest cycle life? If you have, you really do need to get out more.  If that is not an option, you could check out my posts of the Hero Batteries, both Part 1 and Part 2. 

Did you just find out about a new breakthrough in batteries in some website that promises to increase the energy density by a factor of 10 with some sort of alien tech?  Are you wondering when that will hit the EV in your dealership?  Wondering when the next alien tech will hit the battery community?  Check out my guide to battery breakthroughs. 

Are you one of those who can’t read the book but is happy to watch Peter Jackson’s movie adaptation of the Lord of the Rings?  Are you in the mood for a quick 1h, easy to digest overview of the status of batteries, how far we can get with future advances, and what is stopping us from getting there, all recited in a charming Indian accent?  Check out my presentation at Princeton here.

Finally, wondering why there is all this sudden talk about how one can create jobs in energy technologies in the US? All in the last 3 months? (Hint: Check the news).  Wondering why TWiB is not jumping on this bandwagon?  Because I said it 3 years ago: long before it was fashionable!  And I said it in the aforementioned charming Indian accent.  Check out this video in the Fremont Cleantech Open.

There you have it.  One easy to digest post that tells you all you need to know about batteries. 

Can I just say that when I go back and read some of these old posts, I’m amazed at how smart I used to be.  I’m sure all seven of my regular readers can attest to the decreasing quality over time.
