➀ Researchers at Dalhousie University have developed a new type of lithium-ion battery with a single-crystal electrode that lasts over 20,000 cycles before reaching the 80% capacity threshold, equivalent to driving 8 million kilometers; ➁ The single-crystal design resists the damage typically caused by repeated charging and discharging, unlike traditional lithium-ion batteries; ➂ This technology could significantly improve the durability and sustainability of electric vehicles (EVs), and potentially outlast other vehicle components.
