Researchers have developed a new high-performance, the grid-scale battery made from metal scrap and common household chemicals.
The proof-of-concept battery, which is no bigger than a pill bottle, could withstand the equivalent of 13 years of daily charging and discharging while retaining 90% of its capacity, researchers said.
Cary Pint, an assistant professor at Vanderbilt University in the US, said the battery is powerful and easy-to-build and represents a new kind of approach to innovation.
Pint and his students were inspired by an ancient technology called the Baghdad Battery, which dates to the first century BC.
It consisted of a terracotta pot, a copper sheet and an iron rod along with some trace chemicals that could have been an electrolyte, 'Live Science' reported.
The team soaked metal pieces in a jar with a solution of water and salt or a solution of water and antifreeze.
They then applied a voltage to induce a known process called anodization, which restructures the nanoscopic composition of a metal.
Researchers placed a physical barrier between the two pieces of metal and submerged it in an electrolyte solution made from water and potassium hydroxide.
When connected by wires to a device that generated a current, such as a solar panel, their contraption worked just like a car battery.

That exposes the metal's interior surface and makes it more receptive to storing and releasing energy.
