The World’s Biggest Lithium-Ion Battery

The world’s largest lithium-ion battery will be installed in South Australia in an effort to bolster the state’s energy supply, Jay Weatherill, the premier, announced today.

The energy-storage system will be delivered by Tesla and the French renewables company Neoen, which will be using its Hornsdale Wind Farm for the project.
