Then it sells the powder to a battery manufacturer - Sila would not identify the other company - which slots the material into its existing process, producing the new battery for the Whoop fitness tracker. Today, the company produces this silicon powder from its small facility in Alameda. This is possible thanks to the chemical makeup of the anode, the cathode and the surrounding parts of the battery. When you turn the car on and drive down the road, the battery provides electrical power as the atoms move into its other side, the cathode. When you plug an electric car into a charging station, lithium ion atoms gather on one side of the battery, called the anode. That is why they are called lithium-ion batteries.

In that state, these lithium atoms are said to be ionized. This generates power because each atom is in a positively charged state, meaning it is missing a single electron. Today’s batteries are based on the back-and-forth movement of lithium atoms. It sells a new material - a silicon powder - that can significantly boost the efficiency of batteries, and plans to build them using many of the same factories and other infrastructure that produce lithium-ion batteries. “If this kind of thing gets into a smartphone or some other consumer device, it is a sign of real progress,” said Venkat Viswanathan, an associate professor of mechanical engineering and materials science at Carnegie Mellon University who specializes in battery technologies. But it is indicative of Sila’s hopes to push the technology into electric cars and other markets. The fitness tracker, a device with a small market niche, may seem like a baby step. A decade later, those efforts are beginning to bear fruit. The agency nurtured the new battery companies with funding and other support.
