ELECTRONICS can store 50,00,000,000 of the most powerful and dangerous lithium ions in the earths crust for up to a million years, researchers at the University of Exeter have discovered.
The researchers have dubbed the material ‘alesis’ and have named it after the Greek word for “electronic drums”.
“We were able to record and analyse the electron emissions from the sodium-electronic drum using a detector that we had developed,” said Dr Sam Firth, a postdoctoral researcher at the university.
“It is a device with more than one million electronic drum electrodes and many different electrodes.”
Electronic drums contain more than half a billion sodium atoms, with about 10 million ions per drum.
The amount of sodium atoms varies with the shape of the electrode, but it can be as high as 200 million ions.
Dr Firth said the sodium electrodes could be used in electronic drums to store electrical energy, or to use as electrodes for other applications.
“If you want to build an electronic drum, it is not really practical to make all of the electrodes of the drum,” he said.
“The electrodes could then be reused and it is the electrodes themselves that have to be recycled.”
There are many applications for these drums, including storing electricity for electricity generators, or powering a generator for energy harvesting, for example.
“The researchers were able by using a method called “bead analysis” to analyse the electronic drums.
The method was able to detect about 10,000 different types of sodium ions.”
There is no question that sodium is an incredibly strong material and it’s extremely difficult to produce in large quantities,” Dr M. John Mather, a chemistry professor at the department of chemistry and biological sciences at the National University of Singapore, said. “
In theory, this could be enough to store up over 1 million tonnes of lithium.”

“There has been much effort and many attempts to make it.
However, this is the first time we have been able to demonstrate it in a controlled way.”
Electronics used to store energy could also be used to generate electricity, Dr Futher said.
It was known that the electronic drum could store electricity for up a million to a billion years.
It could also potentially be used as a catalyst for converting CO2 into hydrogen and vice versa.
“The electrodes of an electronic device can act as a battery, which means they could be recharged at a very fast rate,” he added.
Electronic electrodes are made up of layers of aluminium oxide, which can be made by melting aluminium powder.
Electronic devices that contain electrodes are also known as “electrical devices” and are often made from aluminium.
The research has been published in the journal Nature Materials.
