QuantumScape is a technology company focused on developing solid-state lithium batteries for electric vehicles. Founded in 2010, it aims to improve battery performance, safety, and longevity compared to traditional lithium-ion batteries. Solid-state batteries use a solid electrolyte instead of a liquid one, which can potentially lead to higher energy density and faster charging times. The company has partnered with major automotive manufacturers, including Volkswagen, to accelerate the commercialization of its battery technology. QuantumScape went public in 2020 through a merger with a special purpose acquisition company (SPAC), gaining significant attention in the electric vehicle market and the broader clean energy sector.
