Stanford Develops Fast-Charging, Stable Aluminum Battery
An anonymous reader writes: Stanford researchers have announced the creation of an aluminum-ion battery that they say will charge quicker, last longer, and be generally safer than common lithium-ion batteries. "Aluminum has long been an attractive material for batteries, mainly because of its low cost, low flammability and high-charge storage capacity. For decades, researchers have tried unsuccessfully to develop a commercially viable aluminum-ion battery. A key challenge has been finding materials capable of producing sufficient voltage after repeated cycles of charging and discharging. ... For the experimental battery, the Stanford team placed the aluminum anode and graphite cathode, along with an ionic liquid electrolyte, inside a flexible, polymer-coated pouch." The researchers' main challenges now are getting the battery to produce a higher voltage and store energy at a higher densities.
Don't be stupid. We're fucking up our planet because of our addiction to fossil fuels. If this actually pans out, then it'll make electric vehicles very economical, and will completely obsolete gasoline-powered cars, which is easily the biggest source of our carbon pollution. We'll need more electric generation capacity of course, but that can be done with lots of different sources, including carbon-free ones such as solar, wind, tidal, and nuclear.
With the obvious problems with our environment at this time, it's my opinion that replacing gas cars with EVs ASAP is a screaming emergency.
