Over the last three years, electric vehicle sales in the US have been steadily increasing but only adding a small number of new buyers every year, according to the Electric Drive Transportation Association. In Europe, meanwhile, countries like Germany have seen numbers stagnate. One of the biggest issues facing the wider uptake of electric cars is the still-lagging battery technology.
If engineers could increase batteries’ energy storage capacity and decrease the time needed to charge them, the lithium-ion batteries used in modern electric vehicles would become much more efficient. This improvement is just what the University of Limerick (UL) in Ireland is targeting. Researchers there are working with the elements germanium and silicon, which they say could double battery life even after being charged and discharged more than 1,000 times.
