Substances can exist in three states of matter - solid, liquid and gas. Substances can change states. To change the state of a substance energy must be transferred to, or from, the substance.

Does it feel like a solid, liquid, or gas? Leave the shaving cream blob out overnight. Look at it very closely the next day. How has it changed? Leave it for a few more days. Has its state changed?

Liquid potassium anodes show 100x performance boost—but a new solid electrolyte is key to room-temperature use.

It changes from water (liquid) to ice (solid). Explain that another change in state is when liquid water cools enough and freezes to form ice. Instead of changing from a liquid to a gas, like in ...

Penn State researchers developed a low-temperature (150°C) method to produce solid-state battery electrolytes.

The ideal SSB substitutes that liquid for a fully solid electrolyte, made out of materials like oxides, sulfides, or polymers. There's also an intermediate product known as a semi-solid state ...

Semi-solid state batteries, on the other hand, use a gel-like electrolyte instead of a fully liquid or solid one ... which have backup gas generators to charge the battery.

Most EVs use “wet” lithium-ion batteries containing liquid electrolytes to move energy around. Solid-state batteries, which have been slow to come to market, promise faster charging speeds ...
