'Superbattery': New Lithium-ion Battery Technology Invented by a 94-Year-Old Professor

A team of engineers led by 94-year-old Professor John Goodenough, the co-inventor of the lithium-ion battery have developed a new longer-lasting battery technology that can't catch fire.

Mail Online reports that Lithium-ion batteries are one of the most popular types of rechargeable batteries used in many mobile devices, but they can sometimes explode and catch fire - as was the case for Samsung's Galaxy 7 exploding battery fiasco.

Goodenough is now working on solid-state batteries, with his team at the University of Texas at Austin claiming they are the latest bunch to crack this potentially disruptive new form of power. The all-solid-state battery cells are noncombustible, apparently robust enough to take today's high number of charging cycles and, critically for everything that's electric, have three times the energy density as current li-ion cells.

The researchers showed that the new battery has at least three times the energy density as current lithium-ion batteries and it could be used for mobile devices, electric cars and stationary energy storage.

The new battery has glass electrolytes inside it instead of liquid ones, enabling the researchers to use an alkali-metal anode which doesn't form dendrites. Another advantage of the batteries is that they can be made from earth-friendly materials.
