Cobalt-free batteries could power cars of the future
Most electric cars are powered by lithium-ion batteries, a type of battery that is recharged when lithium ions flow from a positively charged electrode, called a cathode, to a negatively electrode, called an anode. In most lithium-ion batteries, the cathode contains cobalt, a metal that offers high stability and energy density.
Designing better batteries for electric vehicles
But it''s proving difficult to make today''s lithium-ion batteries smaller and lighter while maintaining their energy density — that is, the amount of energy they store per gram of weight. To solve those problems, researchers are changing key features of the lithium-ion battery to make an all-solid, or "solid-state," version.
Your Guide to Home Backup Batteries in 2024 | EnergySage
Batteries store energy produced now for use later, providing flexibility for meeting your demand with supply. If you only have solar panels, any electricity they generate that you don''t use goes to the grid. Batteries enable you to store that excess electricity instead so you can use it when your panels aren''t producing enough to meet …
