A new type of lithium-ion battery with a single crystal electrode can withstand over 20,000 charge-discharge cycles before hitting the 80 percent capacity cutoff.
Researchers at Dalhousie University studied the battery using an ultrabright synchrotron after it underwent continuous testing for six years. If it were fitted onto an electric vehicle (EV), this would roughly translate to a distance traveled of nearly five million miles (eight million km).
While pushing the adoption of EVs, the US has also mandated by law that batteries retain 80 percent capacity even after eight years of operation. However, industry experts believe that technology needs to advance sufficiently so that batteries can outlast the vehicle itself.
