Women In Power: Ann Marie Sastry Races To Create Next-Gen Batteries -- Khosla And GM Bet She Can Win

Posted: 06/26/11 01:15 AM ET

A special series profiling trailblazers in energy innovation and champions of the environment. See previous stories here.

"In my family the expectation was that I would contribute," says Ann Marie Sastry. "My dad was a huge inspiration to me. He was my hero. And the expectation was there from a very early age that, 'Of course, I would do mathematics. Of course, I would be interested in science.' That is a huge advantage--that expectation that you will not only be competent at the sciences and technology, but also that your aim is to make a difference."

One can only imagine how proud Sastry's father must be. As President and CEO of Sakti3--a promising next-generation battery startup backed by the likes of Khosla Ventures and G.M. Ventures--and Professor of Mechanical, Biomedical and Materials Science and Engineering at the University of Michigan, she has clearly embraced the lessons of her childhood. "Sakti is Sanskrit for power and three is from the atomic number of lithium and the three founders of the company," Ann Marie explains. "But the name does comprise a bit of an homage to my father, who is from India and a math professor."

Not all girls grow up with such a powerful mentor and Ann Marie seems well aware of this. When asked about the underrepresentation of women in the STEM (science, technology, engineering, math) fields, she says, "We, as a culture, as an academic community, and as an industrial community need to make the opportunity clear to all groups."

But Sastry sees herself as "more of a glass-half-full kind of a guy." There is "ample evidence of gender bias. That is incontrovertible," she says. But at the same time we see young women being much more successful in both early and secondary, and graduate and post-graduate education than young men. And there are a number of studies that show that women's assessment of their own performance is persistently lower than men's. But the women's assessment in carefully controlled sociological and psychological studies hews closer to the fact."

When asked what she takes away from those findings, Ann Marie replies, "Well, Women are right. My feeling is that realism is very helpful to women and girls as they go through a formalized educational program. Not being armed with over self-esteem is not always a bad thing. One thing I tell everybody that I work with--especially students--is that if you want to have high self-esteem, do something estimable. You can read yourself a mantra in front of the mirror every morning before you go to work, but that's no substitute for going to work."

And if the observations of Sakti3's founding investor are any indication, Sastry lives by her own words. In the fall of 2007, venture capitalist Samir Kaul--who leads one of the world's largest clean technology investment funds at Khosla Ventures--traveled to Michigan. "Because my wife and I both went to [the University of] Michigan, I'm always on the lookout for technology out of Ann Arbor--they have terrific research," he explains. "A number of different people pointed me towards Ann Marie as a shining star in battery technology."

After conducting the requisite due diligence, Samir swiftly placed his bet. "At Khosla, we look for big markets and special people and Ann Marie certainly qualifies in the category of special people," he says. "We probably decided to invest within six weeks. She is very strong academically and has excellent business instincts--which is a rare breed. And she reaches out a lot for advice. She's just as much a student as a teacher."

Kaul is also impressed by Sastry's team-building skills: "She's not afraid to hire really good people around her--Bob Kruse who ran the electric vehicle program at G.M. and [another] very senior manufacturing guy from Dow. She's fiercely loyal and really goes to the mat for her folks."

When reflecting on her career, one of the first things Ann Marie emphasizes is the importance of collaboration. "I have been fortunate to have terrific collaborators over the years and sometimes I'm the math guy and the other person is the applications guy, and sometimes I'm the applications guy and I have to find a chemist or a materials scientist or a physicist to work with," she says. "But what unites the teams that I've been privileged to lead is a shared mission to do with the ultimate aim of the project and that typically is a societal aim."

As for the work ahead, Sastry says the energy density of batteries must double "if we're to have a serious impact on the market with electric vehicles." That translates to twice the range, or "doubling the size of your electric gas tank." She sees battery cells eventually being replaced by other technologies, but not for "decades to come."

But in the face of serious competition from a slew of other startups and more established players like A123 Systems and LG Chem, what gives Sakti3 a leg up? First: The company's solid-state batteries just landed on the annual list of 10 emerging technologies predicted to have the greatest impact by MIT's technology review.

Second: "We started the company based on a series of rather detailed calculations to do with what was achievable in a next-generation battery. We thought battery cells should be designed with proper computational modeling. We're very focused on disruptive technology," Ann Marie explains. "The other thing we did was focus very hard on equipment that was scalable, because the bottom line is these battery cells need to be affordable. We'll be sending prototypes to others this year and hope to bring it to scale within the next few years."

True to form, Ann Marie approaches the realities of entrepreneurship with blunt realism, but she clearly sees a path to success for her nascent company. "We may fail. That means that we're taking appropriate risks. And as far as the competitors are concerned, I certainly hope they're working as hard as we are," she says. "I don't mean that as a throw down. We've got huge numbers of people in the emerging economies that are going to join the middle class and they may adopt the internal combustion engine [instead of electric vehicles] unless the science and technology fields are working hard on energy storage. The markets are enormous and there is room for dozens and dozens of companies to fill the need."

And how will all of those people join the middle class? By having parents that set the same kind of expectations that Sastry's father did. "When you look at the numbers of people going into technology fields globally, they dwarf our own numbers. In prior decades the United States had hegemony in math, science and technology," she says. "It's fading because other nations are becoming very savvy to the fact that people who offer unique capabilities in science and technology are in high demand, and, therefore, can command higher salaries and create a better way of life for their families."

The first priority should be to figure out what people are FOR, not what they WANT. Most of the things we are sold are not needed, and provide no usefulness to future generations. Stop the madness of moving people around all the time! The automobile is a tax levied by oligarchs when we believe we have to have jobs and trinkets to keep us happy. This technology should be first applied to local needs, such as small farms and gardens, wheelchairs and artificial limbs. Just because the auto industry has a lot of power to coerce money from people and government does not mean they should get the right to keep people enslaved to daily transport.

If you want to outsmart the anti-science crowd, calculate the growth rates of these technologies. You will find they are surprising consistent. I found that battery capacity/weight is improving at 9% per year and installed solar capacity (as an unrelated example) is growing at 8% per year. Then it becomes like working with compound interest. How long before battery capacity/weight doubles? Probably about seven years. And then it double again 7 years after that.

Battery technology is driven by demand and markets. It's been on going for over a hundred years. It has nothing to do with 'green' initiatives.

That doesn't make sense. If the cost and or weight, size of batteries falls by an appreciable amount, then electric cars will be much more successful. That has a whole lot to do with green initiatives.

I love it! I have met some of the smartest people on earth and many of them are women. Only a fool discriminates based on sex.

On the other hand...."As for the work ahead, Sastry says the energy density of batteries must double "if we're to have a serious impact on the market with electric vehicles." That translates to twice the range, or "doubling the size of your electric gas tank." "

That's wrong. State of the art lithium batteries are 1/20th the energy density of diesel. Lithium Surfer batteries, the best energy density known, are 1/10th the energy density of carbon fuels and can only be recharge some 200 times.

MIT Labs is already destroying them in terms of battery life if all they're trying to do is double it. Unfortunately most MITL stuff never leaves the laboratory :(

Pretty cool stuff as long as while they are doubling the power output or storage capacity they do it with materials that are not as bad for the environment as what is currently available or as rare. A viable large scale electricity storage technique (Nothing like the batteries we currently have) is the holy grail of this type of science. That will be the next Robert Fulton, Wright Brothers or Moon landing moment in history.
Keep trying!

Good for her but I wish there had been more information about the 'second generation' batteries. Don't they think women would be interested?

Lead acid batteries become more susceptible to breaking in any transportation vehicle when they are built with increased surface area. For example, check the difference between auto and aviation batteries.

A longer term strategy should not be to keep people in their private vehicles but force them off the roads and into efficient high speed rail. In Europe they have trains that run on magnets. Just the impact of a high speed rail on both coast would take a large amount of commuter aircraft out of the air. Freight and passengers need to be moved more efficiently. The American adherence to private vehicles for commuting and delivering goods is antiquated and short sighted. You commute by rail and have electric vehicle for errands around town. The highway infrastructure is crumbling, lets not make the mistake of wasting money on short term fixes.

This issue is a personal quandary for me. In the medium term I completely agree. But if you examine the growth rates of installed solar, you'll find that we will have a lot of green energy showing up by 2030. After that, I don't see travel as being toxic. We just have to make it through the next 20 years.

Yes hurry up and make those batteries so some corporation can come and pay you tons of money to buy the patent and then bury it so they can never be made.

Let's hear it for Corporations holding the US back from advancing while the rest of the world tramples us. No advancements in technology, education, medicine or otherwise occur unless the powers that be are going to make a crapton of money.

Very astute woman.

I am a woman who had a father like this who invested personally in my knowledge of higher math and scientific curiosity. The only thing that would have worked better in my family is if my chemist mother (MS in Chemistry from Michigan) had worked and he had taken up more of the slack in child care and unpaid work around the house (he was a professor). It also would have helped if he had not been so walled off at experiencing emotion (perhaps he did this to maintain power and status in our family, but it actually made him look very weak and wimpy, and caused trauma to my brother and me as dependent children).

Totally agree with her that economic autonomy in women through their work is the best path to adult psychology and self esteem (although seeking help from counselors may be necessary as well if there is trauma in your childhood). I actually don't think women - or men - should have children until they've accomplished this.

why do I care about her gender- we have to move beyond this sexism
01:59 PM on 06/26/2011
How can you move beyond sexism without looking at gender?

I'm guessing you don't care about her "gender" because she is speaking truth and it threatens your false entitlement as a man - because you haven't looked at gender.
02:07 PM on 06/26/2011
we should not be judged by gender, but by the content of character. It is condescending to have a story that in essence says "look even girls can do science". You need to grow out of your sexism.

Agreed. It annoys me whenever they say this "insert race here" person did this or that, or this "insert gender here" did this amazing thing. Its like, lets just say "this person". I mean why don't we say this person with blue eyes did this or that person with a size 7 shoe did that.

Stop it. Just tell us the person's name and what they are doing. Stop making such a big deal out of their race, sexual preference or gender. That's the only way all these bias things will go away.

As soon as GM is involved it is a safe bet that the product will never make it to market. GM is dedicated to OIL technology and must be pushed into even thinking about green.

The Volt took over 12 years of electric car innovation off the market and now has a 30 km electric range (less than a Baker Electric).

And a 1999 Gen2 EV1 had a range of 160 miles. With current technology, I suspect today's electrics should have a range of 300 miles. I don't know why this stuff isn't here yet. But I think its like watching Greenland melt. We're only watching 57 cubic miles of ice melt each year. But as things accelerate we'll be surprised how fast the world changes.

The Tesla-S (5 passenger sedan, comparable with a BMW) has a 300 mile range and recharges in 45 minutes (the time it takes a driver to have lunch).

We have the technology to change the future.
Sad thing is, the few ultra rich people who are profiting from polluting would rather destroy the planet than take a chance on having slightly smaller numbers in their bank books.
