NAS battery consists of sulfur at positive electrode, sodium at negative electrode as active materials, and Beta alumina of sodium ion conductive ceramic which separates both electrodes.
This hermetically sealed battery is operated under the condition that the active materials at both electrodes are liquid and its electrolyte is solid.
The sceptics are wrong: scientific evidence supports the argument that climate change is a real threat that requires urgent and committed action, says the British government’s chief scientific advisor, David King.
