Irish Researchers Claim Lithium Battery Cycle Life Breakthrough

New germanium nanowire-based anode will allow lithium batteries to charge and discharge more than 1,000 times.

A new nanotechnology that doubles the life of smartphone, laptop and electric-vehicle batteries even after being charged and discharged more than 1,000 times has been developed by researchers at the University of Limerick.

The breakthrough means the research team could be tapping into a market estimated to be worth US$53.7bn by 2020.

“We have developed a new germanium nanowire-based anode that has the ability to greatly increase the capacity and lifetimes of lithium-ion batteries,” said lead researcher Dr Kevin Ryan.

The cleaner and quieter motor is priced at $19,999 and lithium battery packs starting at $15,000.

The trouble with sodium-air is its severely curtailed battery cycle life of just eight charges before it needs replacing.
