The Basics of Li-Ion Batteries There are three components of a lithium-ion battery: the cathode, the anode, and the electrolyte. Cathodes are usually the most expensive and heaviest element of the battery meaning that cathode studies are high priority. The cathode is...
The Beginning of the Lithium Battery For many years, the only suitable battery for portable equipment, such as mobile computing and wireless communications, was nickel-cadmium. Pioneer work on the lithium battery began in 1912. However, it wasn’t until the 1970s when...
What is a Fuel Cell? Fuel cells generate electricity through an electrochemical reaction rather than combustion. Inside a fuel cell, hydrogen and oxygen are combined to generate heat, water and electricity. They represent a clean, efficient, dependable, and quiet...
What are Fuel Cells? Fuel cells use the chemical energy of hydrogen or an alternative fuel to cleanly and efficiently produce electricity. Using hydrogen as the fuel only produces water, heat, and electricity. Hydrogen (the fuel) is supplied continuously, unlike in a...
Electrochemistry is concerned with the range of oxidation-reduction (redox) reactions that cause electrons to transfer between the molecules of reactants. It is the study of the relationship between electricity and an identifiable chemical change, which was first...
