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

They will figure out how to use that extra power somewhere, leaving us at around the same runtime as before.

"They"? Either the device is doing work four times more consuming, your device can stand by four times longer, or your device's battery is approximately four times lighter. Sure, retarded marketing drones are going to figure out a way to stuff four times the amount of adware onto a new laptop, but let's face it, they were going to do that regardless.

Assuming a 4 times increase in battery life at all scales and no size decrease, this would quadruple the range of electric cars - all for a simple battery tech switch. And the batteries are made partly from waste in another industry.

Indeed. I think I've been saying for around a decade "There's nothing wrong with EV's that a battery that lasts twice as long for half the price wouldn't fix'. Assuming this battery is identical to LiIon in cost per pound, the 4X energy density would mean that you could get 'extended range' Model S range at less than the price of a baseline one.

As is, the extended range batteries add so much weight to the vehicle that it adversely affects kwh per 100 miles - the 60 kwh battery is 35 kWh/100m, the 85 drops that to 38.

If an additional 25 kwh of battery currently does that, what happens if you 'only' double the total capacity, cutting the size/weight by half?

I really, really hope this becomes reality. Because I'd like to get an EV or a hybrid without breaking the bank, and it's my opinion that this is the last push needed.
