The particles of a solid are very close together. It melts when it changes from the solid state to the liquid state. The same mass of liquid will have slightly greater volume than the solid. As ...

Scientists have developed a new complex hydride lithium superionic conductor that could result in all-solid-state batteries with the highest energy density to date. Scientists from Tohoku University ...

Sodium superionic conductors with NASICON-type structures—such as Na₁₊ₓZr₂Si x P₃₋ₓO₁₂ (NZSP)—are promising solid electrolytes for solid-state sodium batteries due to their high ionic conductivity, ...
