New All-Solid Sulfur Based Battery Outperforms Lithium Ion

olsmeister writes "The new all-solid battery design uses solid sulfur and lithium, and outperforms existing lithium-ion batteries with four times the energy density. The battery can maintain a capacity of 1200 milliampere-hours per gram after 300 charge-discharge cycles. More work needs to be done, but one would think this new technology could have applications in renewable energy storage, electric cars, and consumer electronics."

Re:...and device runtime with stay the same

Don't get me wrong, I like the added features, but I hope nobody expects laptops that can be used for multiple days in a row without recharging (with sleep mode enabled between sessions of course) or next-gen smart phones that can go a week without recharging. They will figure out how to use that extra power somewhere, leaving us at around the same runtime as before.

I'm much more interested in it for electric cars.

Four times the batter life in a cellphone? Meh - mine already lasts for days.

Four times the range of electric cars? World-changing technology.
