SES: Funding, Investors & Team (Sep 2026)
SolidEnergy manufactures rechargeable cells at a pilot scale for prototype demonstration and specialized aerospace markets. But their real future lies in the materials they supply—anodes and electrolyte—for mainstream markets such as consumer electronics and electric vehicles. They supply these to large Li-ion cell manufacturers to be integrated with a separator and cathode into full cells which can be customized for different applications including drones, consumer electronics, and electric vehicles. Because their anode and electrolyte materials are compatible with existing Li-ion cell manufacturing processes, they can achieve scalability by using existing infrastructure. This eliminates the need for costly infrastructure investment. It’s all part of their open ecosystem. It means a more seamless end-user experience, faster prototyping, and no limits to growth.
SES has raised $414M across 2 funding rounds on record, the most recent a Post-IPO Equity of $275M announced in Feb 2022.
That round is above the $7.5M median round size for Consumer Electronics companies tracked on FundedIQ over the last two years.

About FundedIQ's SES Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for SES is left off this page rather than filled in.
