In the basement beneath Peter Bruce’s feet, massed ranks of batteries discharge and recharge, discharge and recharge. At different temperatures, at different speeds, their cathodes expand, their anodes empty out — and then they go through the whole cycle again.
One day the technology in this Oxford laboratory could achieve one of the greatest goals of modern engineering: creating a battery that can make an electric car as good as a petrol one.
Not, though, today.
“Our challenge is, how do we give it a longer driving range? It’s not good enough now,” Professor Bruce, 62, says. “How can we make it refuel faster? Half an hour to fast-charge a car still isn’t good enough.”
