We are powering a new era of electric transportation with the world’s most advanced Li-Metal battery. SES AI’s approach versus other approaches: SES AI Li-Metal — Energy density, Manufacturability. Key breakthrough: our proprietary and patented liquid electrolyte. SES Al's innovative and proprietary high concentration solvent-in-salt electrolyte composition. SES AI electrolyte uses a high concentration solvent-in-salt approach. A conventional liquid electrolyte is low concentration, where the salt is coordinated by solvent and there are free solvent molecules, rendering the overall electrolyte stability of Li-Metal poor. In SES AI's high concentration electrolyte, the solvent is coordinated by the salt, and there are no free solvent molecules. This allows the electrolyte to achieve unprecedented Coulombic efficiency of99.6% on Li-Metal. Without this high concentration approach, it was thought liquid electrolyte could never achieve such high stability on Li-Metal and high voltage cathode at the same time. Electrolyte composition Salt: A single or multiple salt(s) with purity profile and trade secret purification process Solvent: Proprietary and patented solvent that SES designed and synthesized; not commercially available Additives: Proprietary/trade secret
