New documents confirm Tesla is expanding battery manufacturing and R&D operations in Palo Alto. This essentially confirms Tesla's 'Project Roadrunner', a top secret initiative with the goal of producing battery cells in house (with a cost below $100kWh). With up to 100 people working in 4 shifts 24/7, it seems like Tesla is truly ramping capacity of these new cells. But many questions remain ... Do these cells use the Maxwell Dry Battery Electrode (DBE) tech? Are these cells going into the new Plaid Model S? How many battery packs can Tesla produce in Palo Alto/Fremont?
