Guinness World Record for the highest voltage with a lemon-battery

Royal Society of Chemistry and Professor Saiful Islam and his team from the University of Bath used 2,923 lemons to generate as astonishing 2,307.8 volts.

This new voltage is a new Guinnes World Records™ title for the highest voltage from a fruit battery, which smashed the previous world record of 1,521 volts. 

The lemon-battery was used to launch a battery-powered go-kart race run by the Blair Project in Manchester. You can check it out in this video:

The electrifying feat was designed to highlight the importance of energy storage and the need for new innovations for a zero-carbon world against the backdrop of the COP26 Climate Change Summit.

“It was very exciting to regain our Guinness World Records title by squeezing the highest voltage from a fruit battery. It’s an amazing feat, but it’s still not an effective battery – the amount of electrical power would not be enough to turn on a smart television.

“Batteries have a vital role to play in reducing carbon emissions – and have come a long way with modern lithium batteries helping to power the revolution in portable electronics and mobile phones.

“If we are serious about reaching net zero carbon status we need better batteries – to power more electric vehicles and to store the energy from renewable sources such as wind and solar.

"It’s an exciting time to be a scientist in general and a chemical scientist in particular – as scientific research is crucial to understand how batteries work and to discover new materials that will give us technologies that can store more energy, are safer and recharge faster.

“We also have to be able to recycle and reuse these batteries effectively to enable a truly sustainable energy future.”

Professor Saiful Islam, RSC trustee, professor of materials chemistry at the University of Bath and expert panel member of the Faraday Institution.

    The CSIC White Paper presents the interdisciplinary approaches that the CSIC Research Centers are applying in order to face several of the scientific and social challenges of the next 10 years. CSIC introduced the White Paper in a digital event livestreamed and now archived on YouTube, analyzing several topics across its three areas of work: Life, Matter, and Society. These documents cover the whole spectrum of research, from basic investigation to potential applications of the results achieved, in order to create helpful strategies and organization models to apply when facing the main challenges we will encounter in the coming years.
