The corporate additionally shifted its chemistry focus, and in 2022 it introduced a battery with a silicon anode reasonably than a lithium steel one. That shift may assist make the battery simpler to fabricate.
Since then, progress within the EV market has slowed, no less than within the US, partly due to main pullbacks in funding from the Trump administration. EV tax credit for drivers, a key piece of assist pushing People towards electrical choices, led to late 2025. With the marketplace for giant electrical vehicles in bother, Hu says, “now we’ve to take a look at each market.”
The AI supplies discovery platform on which it’s pinning lots of its hopes is named Molecular Universe. The corporate seeks not solely to offer its software program to different battery firms but in addition to establish new battery supplies and both license them or promote them to these firms.

The platform has already recognized six new electrolyte supplies, based on the corporate. Hu says one is an additive that might assist enhance the lifetime of batteries with silicon anodes.
One of many challenges with silicon anodes is that they have a tendency to swell rather a lot throughout use, which might trigger bodily injury and stop environment friendly charging and discharging. To deal with the issue, the business usually makes use of a fabric referred to as fluoroethylene carbonate (FEC), which can assist kind an elastic movie on the anode so the battery can nonetheless cost successfully. That additive can degrade at excessive temperatures, although, producing gases that may hurt a battery’s lifetime. The SES platform recognized a compound that works like FEC however doesn’t launch these gases.
The corporate’s lengthy historical past and deep battery data may assist make its platform a useful gizmo, Hu says. He sees the precise mannequin as much less essential than SES’s area experience and knowledge from years of constructing and testing batteries.
“By not truly making the bodily battery, we’re truly capable of scale after which generate income quicker,” he says.
However some consultants are skeptical concerning the near-term prospects for AI supplies discovery to revive the business. “New supplies growth, as a lot as we thought that was what folks wished (and, frankly, it must be what the cell makers need)—I do not know that that appears to be the true linchpin of the battery business’s progress,” says Kara Rodby, a technical principal at Volta Vitality Applied sciences, a enterprise capital agency that focuses on the power storage business.
Traders are pulling again, and a slowdown in public assist is making issues tough for some elements of the battery business, she provides: “I don’t know that the flexibility to find any new materials goes to unlock something new for the battery business at this time limit.”
