When electricity is flowing, the cathode gains the same number of electrons that the anode loses. This happens through two different types of chemical reactions. The reaction when the cathode gains ...

Lithium-ion (Li-ion) batteries are an integral part of society, from cellphones and laptops to electric vehicles. While ...

the membrane lies sandwiched between a positively charged electrode (the cathode) and a negatively charged electrode (the anode). In the simple reaction that occurs here rests the hope of ...

Argonne researchers have developed a new class of electrolyte additives for lithium-sulfur batteries, improving battery ...

Oxygen and H+ are formed at the anode (oxidation), and the indicator turns red. Hydrogen and OH- are formed at the cathode (reduction), and the indicator turns blue. After a few minutes, a relative ...
