Could ultra-fast charging stations like this one at the Revelstoke Railway Museum in Canada get even faster?


APPLYING PRESSURE TO EXTEND EV BATTERY LIFE


Daniel Aronov examines whether applying an external force or pressure to certain types of cell could enhance performance, improve safety and extend EV battery life


L


ithium-ion batteries are everywhere. You see them in consumer electronics, electric vehicles, robots and power-


grid storage. Largely driven by falling prices and widespread electrification, global Li-ion demand has grown from a modest 19GWh in 2010 to 285GWh in 2019, with Bloomberg forecasting


8,000GWh by the end of the decade. Although falling prices have a


central role to play in the increase in demand, advances in technologies that support cost reduction and improve battery performance are equally important. While prices (at a pack level) dropped by 89% from above US$1,100 per kWh in 2010 to US$137


per kWh in 2020, improvements in technology have seen the energy density almost triple over the same period. What is more, a move to silicon-rich


anode materials has also provided a stepwise improvement in energy density, as witnessed by StoreDot’s Extreme Fast Charging (XFC)
