Solid Power SPAC Presentation Deck

Solid Power's All-Solid-State Platform is a Revolutionary Advancement Significant improvements over lithium-ion Range 482 vs 266 miles¹ Battery Life More than double the current 8-year calendar life² Safety Non-volatile, 100% solid-state TAL Cost Lower material and pack system costs at scale Next Gen Compatible with next gen cathodes driving the next leap Note: Solid Power cell performance metrics are initial commercialization design targets for lithium metal anode cell. 1. Comparison based on a 77 kWh lithium-ion pack with cylindrical cells (i.e. Tesla Model 3 Pack) with a system volume of 329 L. Solid Power mileage assumes a constant 329 L system volume delivering 138 kWh with a pack mass of 481 kg utilizing lithium metal anode cell design. 2. Solid Power estimates. Solid Power DCRC 8
