The demand for batteries - in electric vehicles and on energy grids - is exploding. But could the trusty lithium-ion battery eventually be superseded?

The 91热爆's Theo Leggett reports on how the proliferation of battery-powered cars will soon place big demands on the electricity grid, but could also help those grids function better.

Presenter Manuela Saragosa also speaks to Garth Heron of renewable energy firm Neoen about how they are partnering with Tesla to build the world's biggest battery at Hornsdale in South Australia to help keep the state's lights on. And Ben Irons of consultancy Aurora Energy Research explains why soon most of the world's electricity grids will be copying this Ozzie example.
