'''QuantumScape''' Corporation is an American company that researches and develops [solid-state](/source/Solid-state_battery) [rechargeable lithium metal batteries](/source/Rechargeable_lithium_metal_battery) for use in [electric car](/source/electric_car)s. It was founded in 2010 and is headquartered in [San Jose, California](/source/San_Jose%2C_California), employs around 850 people.[ Major investors include [Volkswagen Group](/source/Volkswagen_AG) and [Bill Gates](/source/Bill_Gates).][{{cite web|title=QuantumScape Corp|website=[Bloomberg News](/source/Bloomberg_News) |url=https://www.bloomberg.com/profile/company/0561526D:US|url-status=|access-date=|archive-url=|archive-date=}}] In 2012, QuantumScape began working with German automaker [Volkswagen](/source/Volkswagen).
In 2018, Volkswagen invested $100 million in the company, becoming the largest shareholder. In the same year, Volkswagen and QuantumScape announced the establishment of a joint production project to prepare for mass production of [solid-state batteries](/source/solid-state_battery).[{{Cite web|last=Wayland|first=Michael|date=September 3, 2020|title=Bill Gates-backed vehicle battery supplier to go public through SPAC deal|url=https://www.cnbc.com/2020/09/03/bill-gates-backed-ev-battery-supplier-to-go-public-through-spac-deal.html|access-date=September 9, 2020|publisher=CNBC|language=en}}] In June 2020, Volkswagen invested an additional $200 million.[{{cite web|title=VW-Partner QuantumScape geht an die US-Börse|url=https://www.electrive.net/2020/09/04/vw-partner-quantumscape-geht-an-die-us-boerse/|url-status=|access-date=|archive-url=|archive-date=|last=Philipp K|date=September 4, 2020|language=de-DE}}]
In 2020, QuantumScape merged with the [special-purpose acquisition company](/source/special-purpose_acquisition_company) Kensington Capital Acquisition.

On June 26, 2022, the company announced the production of a [solid-state battery](/source/solid-state_battery) with a range of 650 km and a charge time of 15 minutes.[{{cite web|url=https://www.popularmechanics.com/science/a40230247/solid-state-batteries-electric-vehicles/|title=A Revolutionary Solid-State Battery Is Nearly Here, Scientists Say|author=Eric Tegler|date=June 21, 2022|access-date=July 1, 2022}}]
At the beginning of 2024, Volkswagen and QuantumScape presented a battery prototype in a press release based on the technologies developed by QuantumScape, which has 1000 charging cycles with only 5% capacity loss and an [energy density](/source/energy_density) that is at least a third higher.[{{Cite web |title=Feststoffzelle von Quantumscape besteht laut VW Härtetest |url=https://www.golem.de/sonstiges/zustimmung/auswahl.html?from=https://www.golem.de/news/1-000-ladezyklen-feststoffzelle-von-quantumscape-besteht-laut-vw-haertetest-2401-180786.html&referer=https://de.wikipedia.org/ |access-date=2024-02-17 |website=www.golem.de}}] In July 2024, VW PowerCo and QS announced an agreement for volume production.

In October 2024, QuantumScape introduced a prototype of their first planned commercial product they are calling QSE-5. The QSE-5 B-sample cell has a measured cell energy of 21.6 Watt-hours (Wh) at C/5 discharge rate and 25 °C. This is divided by the cell volume to get the ''volumetric energy density'' of 844 Wh/L or by the cell mass to get the ''gravimetric energy density'' (also called ''specific energy'') of 301 Wh/kg.
