Researchers Discover a Surprising Way To Jump-Start Battery Performance
A study conducted at the SLAC-Stanford Battery Center has found that charging lithium-ion batteries at high currents right before they leave the factory is 30 times faster and can extend battery lifespans by 50%.
A lithium-ion battery’s very first charge is more momentous than it sounds. It determines how well and how long the battery will work from then on – in particular, how many cycles of charging and discharging it can handle before deteriorating.
In a study published in Joule, researchers at the SLAC-Stanford Battery Center report that giving batteries this first charge at unusually high currents increased their average lifespan by 50% while decreasing the initial charging time from 10 hours to just 20 minutes.
