Designing better batteries for electric vehicles
"Atoms start going places that they shouldn''t, and battery performance declines," says Huang. As a result, much research is devoted to coming up with methods of stabilizing interfaces in different battery designs. Many of the methods proposed do increase performance; and as a result, the cost of the battery in dollars per kWh goes …

What is a Battery?
Introduction. Batteries are a collection of one or more cells whose chemical reactions create a flow of electrons in a circuit. All batteries are made up of three basic components: an anode (the ''-'' side), a cathode (the ''+'' side), and some kind of electrolyte (a substance that chemically reacts with the anode and cathode).
