Ev Batteries Suppliers in United States

QuantumScape is a Silicon Valley-based company pioneering solid-state battery technology for electric vehicles. Founded in 2010 and backed by Volkswagen, QuantumScape’s goal is to commercialize a lithium-metal solid-state battery that can deliver a step-change in energy density, charging speed, and safety. The company has developed a proprietary ceramic solid electrolyte separator that enables the use of a pure lithium metal anode, eliminating the graphite/silicon anode and thus significantly increasing energy per cell. In late 2020, QuantumScape publicly demonstrated single-layer cells with impressive performance, and has since been advancing to multi-layer cell prototypes. The technology promises up to 80% greater energy density than today’s Li-ion, and the ability to charge to 80% in 15 minutes, all while being safer (non-flammable) and with longer life. QuantumScape is in R&D phase with a pilot line (“QS-0”) in San Jose and plans for a larger pre-production line (“QS-1”) with VW in Germany. The company’s development timeline targets automotive sample deliveries in coming years and mass production mid-decade. As a high-profile startup with a successful public listing, QuantumScape has drawn attention for its potential to revolutionize EV batteries. While challenges remain in scaling and durability, QuantumScape’s solid-state cells represent one of the most promising pathways to dramatically improve EV range and convenience, and the company is intensely focused on turning that promise into commercial reality.
