QuantumScape is sprinting toward the successful commercialization of forever batteries.- Given the technical data reported yesterday, we firmly believe that QuantumScape will launch workable forever battery samples in 2022-23.
- And by 2030, this company will produce millions of batteries every year to power nearly everything.

QuantumScape is sprinting toward the successful commercialization of forever batteries.
Description
- Subsidiary: QuantumScape Battery, IncFounded: 2010Headquarters: San Jose, CANumber of employees: 570 (2021)
- QuantumScape will host a live webcast at 2:00 p.m. Pacific Time (5:00 p.m. Eastern Time) today, April 26, 2022. Participating on the call will be Jagdeep Singh, chief executive officer and co-founder, and Kevin Hettrich, chief financial officer, of QuantumScape.
- """""A: Most of the benefits of solid-state stem from the ability to use lithium metal as the anode. Using lithium-metal as the anode requires a solid-state separator that prevents dendrites and does not react with lithium. Once you have such a separator, you can use lithium-metal as the anode and realize the benefits of higher energy density, faster charge, and improved life and safety. QuantumScape has developed such a separator based on its proprietary ceramic material and uses a pure lithium-metal anode with zero excess lithium to deliver the above benefits. QuantumScape couples this solid-state ceramic separator with an organic gel electrolyte for the cathode (catholyte). The ceramic separator also enables our battery design to use a customized catholyte material, better suited for the voltage and transport requirements of the cathode. The requirements for the ceramic separator are different from that of the catholyte. The former requires dendrite resistance and stability to lithium-metal. The latter requires high conductivity (given the thicker cathode), high voltage stability (given the cathode voltage), and the ability to make good contact with the cathode active material particle. It is difficult to find materials that meet both these requirements and attempts to do so often result in a material that meets neither requirement well, resulting in cells that can fail from dendrite formation while also not providing sufficient conductivity to run at high power.
- QuantumScape’s solid-state lithium-metal battery technology is designed to provide both high specific energy and high energy density.
- A: The QuantumScape separator material is a ceramic capable of meeting the key requirements of high conductivity, stability to lithium metal, resistance to dendrite formation, and low interfacial impedance
- Ceramics in general are stable to very high temperatures, and our ceramic separator is no exception. In addition, even at very high temperatures, it does not burn (since it is already oxidized), therefore we believe that it will provide a thermally stable barrier between the anode and cathode.
- If we are able to generate the same level of performance in our commercial battery cells at the targeted level of energy density, this would be the equivalent of approximately over 300,000 miles for a vehicle with a 300-mile pack, or even greater range given the fact that higher target energy density of the QuantumScape cehttps://jobs.lever.co/quantumscape
- lls (1,000 Wh/L) enables even greater range than 300 miles.
- When one considers other markets such as stationary storage for the grid and consumer electronics, the market is even bigger, so the world will need all its battery factories producing at full capacity to meet the potential future demand.
- During our development process we also created over 200 patents and applications to protect our unique approach.""""""
