PolyPlus Packs 10X the Energy of Li-Ion into Waterproof Battery

Jun 29, 2009, 8:20 AM by Eric M. Zeman

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.

When, when, when????. . . .

From time to time we see articles about some battery break through technology, that is supposedly being "tested", but here we are less than 6 months from 2010 and nothing actually reaches the real world consumer market. I am so, so sick of reading about breakthroughs and tests, so far the best batteries in cell phones are 1700mah, so I keep wondering when, when is such a tech actually going to reach the real world consumer market???

Keep in mind that conditions in the lab are far different than the real world.

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...

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 ...

No, what I really would like to know if this technology can be used in cars. The Chevy Volt due out in the Fall of 2010 is only practical because GM found a way to help dissipate the heat from the Lith-Ion battery pack used to power the car (we are a...

Tesla Model S and Roadster

Tesla Motors' first production vehicle, the Tesla Roadster, is an all-electric sports car. According to test results from an EPA certified laboratory, the car has a range of 221 miles (356 km). This is with a lithium battery. If replaced with this Polyplus Pack one could expect ten times the range, but let's play it safe and say it (only) gets five times increase. That woud still be a 1,000 miles on a single charge!

Just make sure you plug it in to an outlet before you do 🤣
