Solid Power DCRC+ Financial Overview

Compelling Market Opportunity The Industry Leaders are Pursuing a Sulfide-Based Solution Competing electrolyte material pathways to enable All-Solid-State Oxide Sulfide Commentary Oxide Polymer Conductivity О Manufacturability Thermal Stability Li Metal Compatibility Moisture Stability Representative Companies Source: Solid Power estimates. Solid Power DCRC+ О Polymer ■ Small temperature performance range requiring additional heating ■ Flexible and elastic Easy to process " Conductivity an order of magnitude lower than sulfide Rigid and brittle ■ Ceramics require complex and hard to scale sintering ■ Not practical for catholyte Sulfide Highest ionic conductivity; comparable to liquid electrolytes Compressible at room temperature Easy to process BOLLORÉ Quantum) Scape ionic AGC MATERIALS ProLogium + ion Storage Systems QHydro-Québec О Solid Power HYUNDAI TOYOTA MITSUI KINZOKU SAMSUNG Fidemitsu NGK LG Panasonic ■ Stable up to 120 °C May require pack-level cooling ■ Stable up to 500+ °C ■Stable up to 450 °C ■ Does not only conduct Li ions which complicates Li plating ▪ Use water-reactive salts Chemically stable but dendrite prevention is a challenge Requires surface coatings and/ or moisture free processing Degradation hurts performance, but no safety hazards Composition must be designed to create stable passivating interface with Li metal Moisture exposure forms H₂S Bare-powder concern; easily- controlled in manufacturing ▪ Limited reactivity in cells Sulfides offer the best balance of performance and mass production 20 20
