From Fast Company, January 9:
Working with a national lab, the software giant used AI to tackle the flaws of today’s lithium batteries—and pave a new path for scientific discovery.
Recently, Microsoft built a clock.
Well, “built” may be overstating things. Members of the company’s quantum computing team found a small digital clock in a wood case on Amazon—the kind you might mistake for a nicer-than-usual trade show tchotchke. They hacked it to run off two experimental batteries they’d created in collaboration with staffers at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL). Then they dressed up its enclosure by adding the logo of Azure Quantum Elements, the Microsoft platform for AI-enhanced scientific discovery that had been instrumental in developing the new battery technology.
The point of this little DIY project was to prove the batteries worked in a visceral way: “You want to have a wow moment,” explains Brian Bilodeau, the head of partnerships, strategy, and operations for Azure Quantum. And the person the quantum team hoped to wow was Microsoft CEO Satya Nadella.
Not that getting Nadella’s attention was such a daunting prospect. Throwing vast amounts of Azure high-performance computing (HPC) resources at a big, hairy technical challenge such as materials research is the sort of challenge he’s predisposed to take a personal interest in. Still, the tangible evidence of success made for a memorable moment: “I was very, very excited to see it come through,” Nadella remembers.
The coin-sized CR2032 batteries powering the clock looked like the ones you might find in a pocket calculator or garage door opener. But on the inside, they used a solid-state electrolyte that replaces 70% of the lithium in garden-variety batteries with sodium. That holds the potential to address multiple issues with lithium batteries as we know them: their limited life on a charge, shrinking capacity over time, subpar performance in extreme temperatures, and risk of catching fire or even exploding. In addition, reducing lithium use in favor of cheap, plentiful sodium could be a boon to the fraught battery supply chain.
With further development, the new material could benefit the myriad aspects of modern life that depend on batteries, from smartphones to EVs to the power grid. But Microsoft, being Microsoft, regards all this promise first and foremost as proof of Azure Quantum Elements’ usefulness to the customers it’s designed to serve. Unveiled last June, the cloud service is currently a “private preview” being tested by organizations such as Britain’s Johnson Matthey, which is using it to help design catalytic converters and hydrogen fuel cells....
