Full Cell Design Audit and Cathode Sourcing Sample Clauses

Full Cell Design Audit and Cathode Sourcing. The goal of this subtask is to finalize full cell stack design that delivers or exceeds 400 Wh/kg and 825 Wh/L. Source cathodes and test cells from potential cell building partners and validate performance. Rank the three identified cell building partners and determine which to move forward with. • Perform a full cell design audit that includes, but is not limited to, the following components and parameters: o Cathode active material – NMC 811, NMC 622, or nickel cobalt aluminum oxide o Cathode loading and porosity – targeting > 4 mAh/cm2 and < 36% porosity o Conductive carbon and binder – input from cell building partner at < 5% cathode mass o Cathode current collector – aluminum or metalized plastic from Soteria o Upper cutoff voltage - > 4.3 V vs. Li/Li+ o Separator – polyethylene or polypropylene with or without ceramic coating at < 20 μm thick o Anode – initially 30 μm thick lithium foil on copper followed by incorporating the output of Task 3 o Electrolyte – Recipient’s current proprietary formula followed by incorporating the output of Task 2; electrolyte volume will be less than 20% excess separator and cathode pore volume o Cell format – standard pouch or cylindrical cell to be finalized with cell building partner and input from ongoing customer discovery • Validate cathode performance from the identified cell building partners. Downselect cell building partner best suited for Recipient’s BRIDGE project objectives. Source cathode supply in support of Tasks 2–4. • Prepare a Full Cell Design Report and deliver it to the CAM for review. This report will cover the key findings, risks, and mitigation actions taken to meet the objectives of Subtask
