About Lilac Solutions, Inc.

Lilac Solutions is a lithium extraction technology company focused on scaling lithium production for the electric vehicle era. Lilac solves the critical technology problems which today prevent development of the world’s largest lithium resources: low yields, high costs, slow start-up, poor reliability, and massive environmental impacts. Lilac’s technology represents such a step-change in performance and cost that it also unlocks the development of new unconventional lithium deposits with low lithium grades and high impurities, which have historically been impossible to produce. In 2021, Lilac raised $150M in Series B financing from investors including T. Rowe Price, Lowercarbon Capital, Breakthrough Energy Ventures, Sumitomo, BMW and SK Materials. Lilac is committed to building a diverse and inclusive workplace.
