Solid-state batteries are an emerging technology that replaces the liquid electrolyte and the separator in conventional lithium-ion batteries with a solid electrolyte. They offer increased energy density, enhanced safety due to reduced risk of thermal runaway, and improved cycle life. However, solid-state batteries face challenges related to manufacturing, scalability, and cost. In the ideal case, the use of solid-state electrolytes enables the use of anode-free cell configurations, meaning there is no anode available during the manufacturing process, but it is created each discharge process in the form of a thin metallic lithium layer on the anode current collector.
