Volkswagen special patent

[car home? Industry] 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 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 promote the development of solid-state battery technology.

At present, the public hopes to strengthen the layout in the field of batteries. Thomas, Chairman of Volkswagen Parts Management Committee? Schmall 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 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 6,543.8 billion US dollars (about 700 million yuan) to become its largest shareholder. The two sides also set up 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 reported 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 (pure electric version of golf) from 300 km to 750 km, and Volkswagen has tested the battery sample of QuantumScape, presumably the test object is PB 18? E-tron pure electric supercar.

In order to speed up the electrification layout, Volkswagen's layout speed in the battery field is also accelerating. 20 19 Volkswagen and Northvolt set up a joint venture company focusing on research and development of power batteries; By the end of May 2020, Volkswagen China invested 1 1 billion euros (about RMB 8.8 billion) to acquire 26% equity of Guo Xuan Hi-Tech. At this point, Volkswagen will become the first foreign-funded automobile enterprise to directly hold the shares of China battery manufacturers. (Text/car home? Peng Fei)
