Quantumscape’s key selling point is its work on rechargeable solid-state lithium anode batteries. These batteries have the potential to enhance EV range by up to 50%, cut charging times to under 15 minutes, and make EVs safer by removing the use of flammable liquids.
A solid-state lithium-metal battery is one that uses a solid-state separator instead of the polymer separator found in traditional lithium-ion batteries. The carbon or silicon anode used in traditional lithium-ion batteries can be changed with a lithium-metal anode when the separator is replaced. The lithium metal anode has a higher energy density than traditional anodes, allowing the battery to store more energy in the same amount of space. Some solid-state designs employ extra lithium to produce the anode, but the QuantumScape concept is ‘anode-free,’ meaning the battery is manufactured without an anode in a drained state and the anode forms in situ on the first charge.
As a result, solid-state lithium-metal battery technology has the potential to increase cell energy density (by eliminating the carbon or carbon-silicon anode), reduce charge time (by eliminating the charge bottleneck caused by the need for lithium to diffuse into the carbon particles in conventional lithium-ion cells), and extend life (by eliminating capacity fade caused by the unwanted chemical side reaction between the carbon and the liquid electrolyte in conventional lithium-ion cells) (by eliminating the anode materials and manufacturing costs).
