3.14 3.15 .... Battery Production The battery production complex represents the production of next-generation all-solid-state batteries (ASSB). ASSBs replace the flammable liquid electrolyte in conventional lithium ion batteries with a highly stable solid ion-conducting material comprised of lithium products produced at the process plant facilities (Section 3.11 and 3.13). ASSBs achieve a substantial increase in battery energy density as compared to conventional lithium ion batteries through the use of lithium metal as the anode material, also produced at the process plant facilities (Section 3.12). The battery manufacturing process will start with mixing the lithium sulfide electrolyte material produced in the processing plant (Section 3.13) to create a slurry. The slurry will then be fed into a roll-to-roll coater, which deposits the material onto a metal substrate. The coated cathode and separator battery components will be combined with a lithium metal anode, produced at the process plant facilities (Section 3.12), via a lamination step to create a single layer of a battery cell. The layer will then be slit and stacked into the desired battery format. Finally, the cell will be packaged and tested prior to leaving the battery production complex. The battery manufacturing facility will be sized for 10 Gigawatt hours of annual ASSB production in
