Presented by Yijin Liu. In batteries, energy is stored in tiny particles within the electrodes that individually breathe in and out and chemically evolve as the battery is charged and discharged.
A cellphone-sized device automatically adjusts a home's power use up or down to save the consumer money and increase the resiliency of the electric grid.
How quickly a battery electrode decays depends on properties of individual particles in the battery – at first. Later on, the network of particles matters more.
Researchers discover they contain a phase of quantum matter, known as charge density waves, that’s common in other unconventional superconductors. In other ways, though, they’re surprisingly unique.
The SLAC/Stanford researcher is a leading materials scientist and entrepreneur whose research is paving the way for better batteries, cleaner power grids.
Charging lithium-ion batteries at high currents just before they leave the factory is 30 times faster and increases battery lifespans by 50%, according to a study at the SLAC-Stanford Battery Center.
