Voltage loss in Li-ion batteries explained
Low-cost electrodes that store more lithium than the ones used in today’s lithium-ion batteries could enable electric car drivers to go farther between charging stops. For that reason, researchers have examined many Li-based electrode materials, searching for better performers.
A family of Li-rich layered transition metal oxides looks especially promising. Compared with common commercial electrode materials, these oxides could, in principle, store 30% or more charge on a volume basis. But the voltage of batteries . . .
