PolyPlus Packs 10X the Energy of Li-Ion into Waterproof Battery
A California company called PolyPlus is working on new battery technology that is waterproof and can store 10 times the energy of today's lithium-ion batteries. Lithium metal-air batteries have been researched for years. In such a battery, air is used as the cathode that interacts with the lithium. The engineering problem to be solved, however, is that water is always present in the air, and water rapidly degrades lithium. PolyPlus has solved this problem with a membrane that protects the lithium, called a protected lithium electrode. It prevents water from coming into contact with the lithium, but still permits the lithium ions to pass through it. Lithium metal-air batteries could be used in a number of different devices that are powered by lithium-ion batteries today, including cell phones.
Scientists Cook Up Quick-Charging Aluminum Battery
Aluminum-ion batteries may replace lithium-ion batteries in mobile devices thanks to a breakthrough made by U.S. researchers.
Sony Hoping to Boost Battery Capacity By 40%
Sony is looking at sulfur to help improve the performance of rechargeable batteries. Sony says using sulfur as an electrode material can increase the energy density from today's limit of 700Wh/L to 1,000Wh/L.
Samsung Researchers Make Battery Breakthrough
A research team working at Samsung has discovered a new way to make lithium-ion batteries that could double the available battery life in devices such as smartphones. The method involves covering silicon nanoparticles with graphene, which prevents the formation of silicon carbide.
AT&T's Latest GoPhone Runs On AA Batteries
AT&T today announced the SpareOne Emergency Phone, a simple handset meant purely to serve as a backup phone for critical situations. The SpareOne runs on AA batteries, rather than a rechargeable lithium-polymer power cell.
MIT Spinout Claims to Double Battery Life
A company called SolidEnergy Systems, a spinout from MIT, says it has new battery technology that will double the life of lithium-based power cells. The breakthrough involves a battery that replaces the traditional graphite anode with a thin, lithium-metal foil.
When, when, when????. . . .
Also, things like cost and safety have to be taken into consideration before something is released to the consumer market. 10x the energy isn't so great, if the batte...
when is such a tech actually going to reach the real world consumer market???
In my opinion, it will not reach the mass market. We may see signs of it around here and there but it will not become the ...
Tesla Model S and Roadster
now i can use my phone underwater instead of this damned air place
Just make sure you plug it in to an outlet before you do
