Stellantis has introduced an funding in Lyten, a Silicon Valley startup that’s growing lithium-sulfur EV batteries made with three-dimensional graphene that promise diminished weight, increased power density and an easier invoice of supplies.

The 2 corporations introduced the tie-up on Thursday. They might not disclose the dimensions of the funding, different to say that Stellantis Ventures, the group’s tech-focused enterprise capital fund, wouldhave a “vital” function in Lyten’s present funding spherical.

Lyten’s lithium-sulfur batteries can be prepared for manufacturing by the top of the last decade, Oliver Gross, senior fellow power storage and electrification at Stellantis, mentioned.

“We needed to discover a know-how that can be nicely deployable inside the Dare Ahead 2030 targets,” Gross mentioned of Stellantis’ strategic plan, which envisages gross sales of greater than 5 million EVs globally by that point, together with one hundred pc of European gross sales and 50 % within the U.S.

Dan Prepare dinner, the CEO and co-founder of Lyten, mentioned the batteries might have as much as twice the power density of present batteries, and that uncooked materials sourcing and manufacturing may very well be localized in North America and Europe. The primary batteries from a pilot plant in San Jose, California, are anticipated to bear testing by the top of this 12 months, Lyten mentioned.

Prepare dinner described three-dimensional graphene as a “supermaterial,” in a position to be tuned to all kinds of makes use of, together with light-weight physique and structural elements, in addition to sensors.

Stellantis and Lyten executives mentioned the primary benefit for lithium-sulfur batteries is their weight financial savings, due to increased power density, which implies smaller batteries and fewer supplies. They may co-exist with different battery chemistries relying on software, Stellantis says.

The startup says that its batteries don’t use nickel, cobalt or manganese and could have a carbon footprint that’s 60 % smaller than conventional lithium-ion batteries.

Graphene historically has been a single-cell two-dimensional sheet of carbon atoms, mentioned Keith Norman, Lyten’s chief sustainability officer, and is tough to fabricate cost-effectively and doesn’t mix nicely with different supplies as a result of it isn’t extremely reactive. It’s additionally not very “tunable,” he mentioned, including that corporations want to switch their very own merchandise to work with it.

Three-dimensional graphene, which is twisted and crumpled into totally different shapes, solves a few of these issues, Norman mentioned. “The reactive floor space is elevated by orders of magnitude,” he mentioned, which helps it bond with different supplies. “It’s extremely tunable for energy, conductivity, weight discount and different traits.”
