It's safer, can store more energy and can last much longer.

Together with fellow researcher Maria Helena Braga, the 94-year-old professor recently led an engineering team which apparently developed a vastly superior alternative to li-ion batteries.

The new power cells use solid glass electrolytes instead of the liquid found in its lithium-ion counterparts. This means that these batteries are much safer, as there won't be any explosions or fires happening due to the formation of dendrites (small “metal whiskers” which can form and cause a short circuit if a li-ion battery is charged too fast).

However, safety isn't the only advantage of these solid-state power cells. They have at least three times as much energy density compared to li-ion batteries, while also boasting much faster recharge rates, greater number of charging/discharging cycles, and the ability to perform well in subzero conditions (-20 degrees Celsius or -4 degrees Fahrenheit). Another major benefit with the new batteries is the fact that they can be manufactured in a cheap and eco-friendly way, as the glass electrolytes allow for the substitution of lithium for low-cost sodium which can be found just about anywhere.

Solid state batteries are the next big thing in battery tech. I'm glad we dumped $100 million in research grants, without them we'd still be focusing on tweaking the 30 year legacy of li-ion instead of focusing on new chemistries and electrolytes.

When will these be in the real world ?
3-5 years for full deployment. This has been in the R&D Labs in universities (thanks to research grants from the US government) for at least 5 years as I keep seeing it pop up every few months. Now they're onto the "how do we scale up manufacturing to bring the price down" phase, which usually takes about 2ish years.

If I had a nickel for every time I heard this....

I would absolutely be thrilled if this time it was true. But color me a skeptic.

By all means, be skeptical, it's best to be so when it comes to product pipelines. That said, the acceleration I've been witnessing over the last several years (again, because of our taxpayer dollars going to research at universities which then get sold off to private companies) makes me optimistic in this regard.

I remember a few years ago there were talks of graphene being the next breakthrough battery technology/advancement. Not quite sure where that is these days as not much has surfaced about it since then.

The problem with graphene is producing it in purity at a mass scale. By definition it has to be one atom thick or it's a different material (which, in finding failed ways to produce it, have resulted in another material that is highly useful in other applications). There's progress made every other day practically, but graphene itself is sound. It's the manufacturing of it that's the bottleneck right now, unfortunately.

Just a few off the top of my head: hydrogen fuel cells (oldie but goodie), a123, lithium Air, lithium superoxide.

My knee-jerk reaction to headlines of this sort is, "Not another perpetual motion machine story!" This ain't that, but power generation/storage does have a long line of "close, but no cigar" technologies. How are we doing with commercial fusion reactors? How about high-efficiency low-cost solar cells? It's not that they can't happen, it always seems to be the challenge of going from lab to large scale. This is really hard stuff, sometimes requiring exotic materials, and perhaps unexpected, enabling breakthroughs in other fields. I've learned to not hold my breath. Just let me know when it arrives.

"A new and more powerful generation of batteries may be made entirely from glass, according to the conclusions of Goodenough and his team of researchers published by the U.K. Royal Society of Chemistry. They store and transmit energy at temperatures lower than traditional lithium-ion packs and can be made using globally abundant supplies of sodium.

The research could result in “a safe, low-cost all-solid-state cell with a huge capacity giving a large energy density and a long cycle life suitable for powering an all-electric road vehicle or for storing electric power from wind or solar energy,” the researchers wrote in the peer-reviewed journal Energy & Environmental Science."

So what this is saying, its more user-friendly.... the options are open to fast charge as speedy as u like without damage, or at least allot faster than fast.. Apple will be all over this.

Exploding batteries will be a thing of the past..... Manufactures will have to find a new way to do their recalls.. and pin it on some "other hardware" design issue.

The relative dielectric constant or battery density is higher that ever seen before, there is no mention of how quickly they self-discharge, and apparently the battery capacity (already quite high) grows over time. And the battery only exists as small scale samples that light up LEDs (no mention of anything bigger), so even if the battery technology exists at a useful size it will still have the graphene problem (how to make a lot of them at a price people will pay). The lab to cheap mass-production step is often difficult, especially if you consider we can turn lead into gold but not at reasonable prices.

As usual, the battery is 3-5 years away from release. And since the first versions will be expensive, they will show up on a $100,000 electric car before they will show up in a $1000 phone.

Unless some company has a demo (look at my smartphone with two week battery life) you might as well not hold your breath.
