Facing the shortcomings of electric vehicles, such as less energy storage, high risk of spontaneous combustion, slow charging and difficult recycling, solid-state batteries have become the research object in the industry. Solid-state batteries are expected by the whole new energy automobile industry because of their outstanding advantages such as energy density, non-flammability, non-corrosion, non-volatilization and non-leakage. Recently, Audi AG plans to increase its stake in QuantumScape, a derivative company that develops solid-state batteries in Stanford University, and will invest an additional 200 million US dollars (about 654.38+04 billion yuan) to focus on promoting the development trend of solid-state battery technology. Now, Volkswagen wants to strengthen its layout in the field of batteries. ThomasSchmall, chairman of the Volkswagen Parts Management Committee, said: "We are making technological progress with our partner QuantumScape, and this investment will effectively enhance our joint research and development of all-solid-state batteries." In terms of strategic development planning, Volkswagen reached a cooperation with QuantumScape in the field of solid-state battery technology as early as 20 12, and in 20 18, it invested $ 1 billion (about 700 million yuan) to become its largest shareholder. The two sides established a joint venture company focusing on solid-state battery research and will set up a pilot factory in 2020. According to Volkswagen's plan, a solid-state battery production line will be established in 2025.
It is understood that QuantumScape has about 200 patents and patent applications for solid-state battery technology. Volkswagen officially claims that QuantumScape's solid-state battery can increase the comprehensive cruising range of e-Golf from 300 km to 750 km. Volkswagen also tested the battery sample of QuantumScape, and it is speculated that the test object is PB 18e-tron pure electric supercar previously equipped with solid-state battery.
