QuantumScape, a solid-state startup, has signed a contract with another "TOP10 manufacturer"
QuantumScape is one of the few start-ups developing solid electrolyte cells that has been described as "promising". The company is already working for Volkswagen and has announced that it has signed a contract with another manufacturer "from the top ten in the world."
QuantumScape and Solid Electrolyte Cells
The name “manufacturer from TOP10” is not given, so it could be Toyota, Ford or Mercedes. Each of the brands mentioned has their own reasons for being interested in QuantumScape cells. Toyota For years, she boasted of independent work on solid-state motors, which resulted in the cars in which they were used ... were NOT shown at the opening of the Tokyo 2021 Olympic Games. Ford looking for partners in the industry, just a few days ago he began a partnership with Tesla co-founder J. B. Straubel. Mercedes finally having problems with the Chinese supplier Farasis.
Of course, the above list is just a guess. Of the top ten, only Volkswagen (because it is already cooperating) and, possibly, Hyundai (which is focused on cooperation with domestic companies).
QuantumScape has announced that the first advanced solid state prototypes will be delivered before 2023, when the QS-0 labeled plant will go online. The factories are expected to produce 200 cells a year, enough for "hundreds of test vehicles". The startup is currently testing 000-layer cells, which is an intermediate step in working with cells with several dozen layers - we should see this in 10.
QuantumScape examines cells Lithium metalwithout an anode, meanwhile, researchers at the University of California, San Diego have presented an intermediate solution between existing lithium-ion cells with liquid electrodes and lithium-metal cells. Well, sulfide-based solid electrolytes have been combined with a silicon anode. They do not require heating and in the first experiments withstood 500 cycles of operation and retained 80 percent of their original power.
Paradoxically, solid electrolytes, which are a problem in themselves, have solved many of the problems with silicon, which is destroyed at the anode by liquid electrolytes. Research work at the University of California, San Diego is being conducted in partnership with LG Energy Solution.
