Reply to comment by OptimalConcept143 in Scientists have developed a solid-state battery material that doesn't diminish after repeated charge cycles, potentially offering a durable alternative to the lithium-ion batteries used in electric vehicles by unswsydney

Huh? It's exactly the opposite.

Liquids typically have a density between 0.7 to 2 kg/l (one of the densest electrolytes used in batteries, sulphuric acid, is 1.84). Common solids go from 1 to 8 kg/l (iron is 7.8) and some even higher. For example, lithium titanate used in the battery is about 3.4 kg/l.
