🔋 Solid-State vs Lithium-Ion Battery: Energy Density, Fast-Charge Dendrites and Thermal Margin

A Blender-built 3D cutaway of a liquid-electrolyte graphite Li-ion cell next to a solid-state cell with a lithium-metal anode. Choose electrolyte, anode, C-rate, temperature and pack size to see energy density (Wh/kg, Wh/L) from capacity, voltage and inactive mass, lithium plating and dendrite growth against critical current density, I2R heating versus cooling thermal margin, and EV range. Typical, approximate values; solid-state is still emerging.
