UK Man Invents Aluminum-Air Battery In His Garage

"Imagine, if you will, a lightweight, inexpensive power source with 9 times the energy density of a lithium-ion battery. Got your mind wrapped around that concept? Now imagine that power source uses recycled aluminum, one of the most abundant metals on Earth, and an electrolyte so nontoxic you can drink it.

Call this power source a battery. Call it a fuel cell. Call it whatever you like. It is an invention that could upend energy storage as we know it and drive the electrification of transportation — from bicycles and neighborhood electric vehicles to heavy trucks, airplanes, and cargo ships — forward at warp speed.


The person behind all this is UK engineer and former Royal Navy officer Trevor Jackson, who began experimenting with aluminum air batteries at his workshop in the Cornish town of Callington in 2001. At that time, the electrolyte used was extremely caustic and poisonous. After years of experimentation, Jackson devised a new electrolyte — whose composition is a closely guarded secret — he says make it possible for his invention to power an electric car for up to 1,500 miles."
