Multilayer Progress

4 Original Premises Behind the QuantumScape Opportunity Combustion powertrains are being replaced by battery-electric powertrains BEV share of global light vehicle market grew from ~3% in 2020 to -10% in 2022* Anode-free lithium-metal technology can offer compelling benefits over conventional lithium-ion batteries QuantumScape has shown an architecture with the potential for greater energy density, and published data showing the ability to charge 10-80% at 45 °C in ~15 minutes with a noncombustible separator QuantumScape can scale up layer count while maintaining cycling performance QuantumScape has successfully scaled up single-layer lab cells to multilayer prototype cells without significant degradation to cycling performance (capacity retention) QuantumScape can scale up production to industrial levels Have demonstrated high throughput separator process *Source: Wall Street Journal, 2023 QuantumScapeⓇ 3
