A team in Cornell Engineering created a new lithium battery that can charge in under five minutes – faster than any such battery on the market – while maintaining stable performance over extended cycles of charging and discharging.
This Review article summarizes the recent research strategies to achieve fast-charging performance of lithium-ion batteries through electrode engineering, electrolyte design, and interface optimization. Rapid development of high-energy-density lithium-ion batteries (LIBs) enables the sufficient driving range of electric vehicles (EVs).
Rapidly cycling (repeatedly charging and discharging) a lithium-ion battery limits the battery's performance over time by significantly increasing the battery's internal impedance (its time-dependent resistance), which hinders the flow of current.
Factory-charging a new lithium-ion battery with high currents significantly depletes its lithium supply but prolongs the battery’s life, according to research at the SLAC-Stanford Battery Center. The lost lithium is generally usually used to form a protective layer called SEI on the negative electrode.
The NIST team, which includes collaborators from the Sandia National Laboratory in Livermore, California, the Naval Research Laboratory in Washington, D.C. and several universities, used two complementary methods to study impedance on the nanoscale in a solid-state lithium-ion battery.
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. A lithium-ion battery’s very first charge is more momentous than it sounds.
