Layered transition-metal oxides are among the most promising cathode materials for sodium-ion batteries because of their high theoretical capacity and low cost. However, conventional designs rely on ...

When substances combine with oxygen the process is called oxidation and the compounds made are called oxides. The sparks in fireworks are made by burning different metals. The burning metals are ...

Scientists have developed a fuel cell system which they say could ultimately have enough energy capacity to power regional electric aircraft. They state that the technology is capable of carrying over ...

Sodium oxide and potassium oxide dissolve in water to produce alkalis: • Na 2 O(s) + H 2 O (l) → 2 NaOH (aq) • K 2 O(s) + H 2 O (l) → 2 KOH (aq) • 2K(s) + 2H 2 O (l) → 2KOH (aq) + H 2 (g) + heat ...
