6 Frequently Asked Questions about “Rare earth silica gel plus battery”
What are sodium rare-earth silicates?
Sodium rare-earth silicates are a new class of materials with a 3D structure framework similar to sodium-superionic conductors (NASICONs). These silicates can be used as a solid electrolyte for solid-state sodium batteries due to their high-ionic conduction (10 −3 S cm −1) at 25 °C.
What is rare earth silicate?
