“A: A solid-state lithium-metal battery is a battery that replaces the polymer separator used in conventional lithium-ion batteries with a solid-state separator. The replacement of the separator enables the carbon or silicon anode used in conventional lithium-ion batteries to be replaced with a lithium-metal anode.”
“A: The higher energy density of QuantumScape solid-state lithium-metal cells, at our commercial target of 800–1,000 Wh/L (as of Dec. 2023), could translate to more range in the electric vehicle, depending on the vehicle design.”
“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.”
“A: Specific energy is the term physicists use to refer to gravimetric energy density, i.e., Wh/kg, whereas energy density is the term they use to refer to volumetric energy density. A cell with higher specific energy will save weight in the batteries themselves and provide additional weight savings in the battery system.”
