Lithium-ion batteries contain nickel, cobalt, and lithium – valuable resources that play a major role in powering electric ...

Ionization breaks the hydrogen atom down into its positive ions (hydrogen protons) and negative ions (electrons). Both types of ions are naturally drawn to the cathode situated on the other side ...

It involves an electrolytic cell with two electrodes named as the anode (positive) and the cathode (negative). The electrolyte is the substance that changes chemically during the electrolytic process.

QuantumScape thinks it solved the biggest problems with its anode-free lithium metal battery that will most likely debut on a ...

In the case of Li-S batteries, a sulfur-containing positive electrode or terminal called a cathode is paired with a lithium ...

The anode (positive electrode) is made from impure copper and the cathode (negative electrode) is made from pure copper. Pure copper forms on the cathode. The slideshow shows how this works.
