LG Chem already supplies cells and batteries for General Motors, Tesla, and Audi, so the addition of another car company to its roster is not a huge surprise. As you can see in the Tweet that Faraday posted today, there are cylindrical cells pictured. Whether this means that Faraday Future's battery will use those kinds of cells (like Tesla does) as opposed to the flat cells that other OEMs go for is unclear. What Faraday is saying is that the deal will result in, "the world's highest energy density for a production automotive battery." VPA is a "universal and scalable modular battery structure" that Faraday says will be used across its upcoming portfolio of vehicles. The details on that, well, are not quite available yet. For now, we'll just have to put together the pieces of what we know so far ourselves.
