Researchers in Australia say they have developed the world's most powerful rechargeable battery using lithium-sulfur, said to perform four times better than the strongest batteries currently available.

What's more, these lithium-sulfur batteries are lighter and cheaper than the widely used lithium-ion batteries and can be produced cost-effectively and in an environmentally friendly manner, the researchers say.
