Q: What are the main benefits of solid-state lithium-metal batteries compared to lithium-ion batteries?

A: Relative to a conventional lithium-ion battery, solid-state lithium-metal battery technology has the potential to increase the cell energy density (by eliminating the carbon or carbon-silicon anode), reduce charge time (by eliminating the charge bottleneck resulting from the need to have lithium diffuse into the carbon particles in conventional lithium-ion cell), prolong life (by eliminating capacity fade that results from the unwanted chemical side reaction between the carbon and liquid electrolyte in conventional lithium-ion cells), improve safety (by eliminating the combustible organic porous separator and organic anolyte material in conventional cells) and lower cost (by eliminating the anode materials and manufacturing costs).

So is this manufacturer wrong?
