Can we build a battery powerful enough to run a phone for a year?
In this Royal Institution lecture, chemist Saiful Islam explores the urgent global challenge of energy storage. Watch as he investigates the chemistry of batteries and attempts to break a world record using nothing but lemons.
As the UK generates nearly twenty times more energy today than it did 80 years ago, the ability to store power effectively has become a vital necessity. Saiful Islam tackles the immense engineering challenge of designing a battery small enough to fit in a pocket yet capable of powering a mobile phone for an entire year.
Marking the 80th anniversary of the BBC's television broadcasts of these lectures, the presentation features a look at hydrogen—the world's most energy-dense fuel—and reimagined classic experiments, including a high-power battery made from lemons.
