Our mission is to power the world’s transition to clean energy by solving the toughest battery materials challenges and manufacturing a clean energy… The world needs cleaner energy. And batteries powered by next-generation materials can help make that possible. Every day, we take on the toughest energy challenges to engineer materials that require less mining, are produced emitting less CO 2 , and deliver enhanced performance to help to lower our dependence on fossil fuels. With deep technical acumen across chemistry, engineering, and material sciences, we take on nearly-impossible technical challenges to develop and commercialize new, better battery materials. Our silicon anode is just the beginning. It’s not enough to engineer innovative materials. To make a difference, scale is critical. We’ve built production technology to bring our materials to the mass market. Our manufacturing is designed with robust production processes, engineered to deploy worldwide, and advances U.S. leadership in clean energy. The introduction of the silicon anode is more than a battery revolution – it’s a product revolution. Close collaboration between OEMs, cell makers, and our Battery Engineering Ser

How it compares to the market

Benchmarked against 207 companies in Climate / Cleantech. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.

Total raised — vs sector median (real $, all stages) 157× above median
This company$1.3B
Sector median$8.1M
Latest round — vs other Growth/Late rounds in sector (real $, this stage) 0.5× of median
This company$374.5M

This company$4.5B

Raised more than 99% of sector peers (real $). Modeled value above 94% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Growth/Late) that last raised in the same ~3-year era, ranked by modeled value est. (not money raised). This is the exact set the analyst read compares against, so a like-for-like cohort is what makes "over/under-valued" meaningful.
