Northvolt AB is a Swedish battery developer and manufacturer, specializing in lithium-ion technology for electric vehicles. The company was founded as SGF Energy in 2015 by Peter Carlsson (now chief executive), who was formerly an executive at Tesla Motors.

Northvolt has a factory in Skellefteå, northern Sweden, and is building another one in Salzgitter, Germany, part of Northvolt's plan to increase production capacity of 32 gigawatt-hours by 2023. Its headquarters for research and development is in Västerås, Sweden.

The opening of a factory in Skellefteå was said to potentially transform subarctic Sweden, and dramatically change the city. It was however said that it could be a potential risk with shortage of qualified labour in the region. The factory will be the largest in Swedish history, creating challenges for newcomers and the existing community. As the energy-hungry battery plant is strategically sited near renewable energy sites, part of the company's stated goal to make "the greenest cell on Earth".

In late December 2021, the company announced that the Skellefteå Northvolt Ett ("One") gigafactory, with 500 workers, had produced its first batch of prismatic cells, as part of its machinery commissioning process. Factory completion and initial customer shipments are expected in 2022. The company projects battery output of 16 gigawatt hours (GWh), enough for ~300,000 EVs, by 2024. With full production lines and staffing, the plant expects to produce 60 GWh of batteries with 3,000 employees.
