The CAFE blog’s recent news about graphene electrode developments by Argonne National Laboratory in applications by Envia, a startup battery company in Newark, California, led to an almost immediate follow-up by another startup, California Lithium Battery (CalBattery), but with a different form factor in mind. The company’s purpose can be divined from their mission statement. “Our mission is to become the leading United States-based developer and manufacturer of advanced, safe, high-performance Very large Format (VLF) lithium batteries for utility energy storage, EVs, and specialized industrial and military applications.” These batteries would be used in transportation and stationary power markets in North America, Europe and Asia. Asked to define VLF batteries, founder and CEO Phil Roberts said that their transportation batteries would come in 40 Amp-hour prismatic packaging, and those for the stationary power market would range up to 400 Amp-hours. This large format approach allows more active materials to be packed into a single package, increasing the total energy density …
