99 percent charge in 30 minutes. Impressive.

Sony may not have the best reputation anymore for its lithium ion battery technology that left so many laptop users checking recall lists (and costing Sony quite a pretty penny) but the Japanese electronics company is still pushing ahead with new innovations.

Now shipping from Sony is a new type of lithium ion secondary battery that uses olivine-type lithium iron phosphate as the cathode material. And what's so special about this? As Sony describes:

"The Olivine-type lithium iron phosphate used in this new battery is extremely suited for use as a cathode material due to its robust crystal structure and stable performance, even at high temperatures. By combining this new cathode material with Sony's proprietary particle design technology that minimizes electrical resistance to deliver high power output, and also leveraging the cell structure design technology Sony accrued developing its current "Fortelion series" lithium ion secondary battery line-up, Sony has realized a high power density of 1800W/kg and extended life span of approximately 2,000 charge-discharge cycles."

Furthermore, these batteries can reach a 99 percent charged state after just 30 minutes of charging. Not only that, but even after 2,000 charge cycles, Sony estimates that these batteries will still hold 80 percent of their original capacity.

Sadly, we won't be seeing this battery technology yet in out laptops and cell phones just yet. Sony said that these batteries will first be used in motor driven devices such as power tools, with application for mobile electronic devices later down the road.

I wonder if these come in the self-conflagrating variety..

Actually, I think the biggest impact this will have is on electric cars, after all the biggest show stopper for current line of electric automobiles is ridiculously high recharge time (~16 hours for full recharge). But having a electric car that can recharge in 30 mins is not that bad.

That feature probably costs extra.

Is this a typical battery article? Available in 2 years... Meaning never...

But will it play Crysis?

Right, and I hope you plan on hooking that electric car into a 470kv power substation to charge it all the way in 30 minutes, because that 15 AMP wall socket and even the Tesla 480v speed charger arent going to be enough to feed a demon like that in 30 minutes.

I doubt they can be used in car's usually fast charging batteries produce a ton of heat, although what do i know about making cars or batteries :)

Yeah, that makes sense, use them in power tools first instead of laptops(less liability if they catch on fire)....

I use my laptop everyday, I use my cordless drill once every 6 months...

One of the maJor shortcomings with quick charging schemes so far is that they come with permanent decrease in battery capacity over time. If this is such a technology the shows very little or no degradation in battery life span and performance this will have a maJor impact on battery technology. Its too bad though that the quantity of lithium in the world couldn't replace all of our gas powered cars. NiZn shows a lot of promise in use in electrics and it was even used in the 1900's for powering cars. Nickel and zinc are non toxic and readily available in the world. Its too bad companies don't like developing a product to sell that they can't patent.

"stable performance, even at high temperatures"

Able to power your electronics AND roast them to medium-rare at the same time!

My VAIO battery pretty much died after 4 months of use. And I wasn't even close to 100 charges/discharges.

So with this new technology, can we expect around 2100 charges/discharges? ;P


PS.

nanotitanate batteries please, 80% charge in 12 minutes and a higher mah than these, though at a cost of a tiny bit of voltage. price to pay, not so high.

Heat is what kills batteries, and as stated in the description provided by Sony, the material has proven to be stable even in high temperatures. Most of the common rechargeable batteries start to stop charging once it heats up, also the heat builds up damage to the batteries which decreases its battery life.

the headline is incorrect. it should read "Sony launches more advanced exploding devices"

I'm hoping that Sony and other companies that build digital cameras will stop making proprietary batteries and just put this new technology in standard AA batteries.

Whats the capacity of current lithium ion batteries. As 1800 Watts per kilogram sounds like quite a bit. Aren't current extended battery packs about 1/2 lb and under a 100 watts. So this would be like 400 watts for the same weight battery.

If it is indeed 4 times the charge for the weight I would welcome this.

It would do just fine in my always run dead Xbox controllers.

You're confusing power density (W/kg) with energy density (WHr/kg). Generally "density" in a battery refers to a measurement per unit of volume (e.g. liter). The above are per unit of mass (kg), therefore, the more accurate terms for the above are:
Specific Power is 1800W/kg.
Specific Energy (WHr/kg) is not stated in the article.

Power density or specific power are useful for determining maximum charge/discharge rates, whereas energy density or specific energy are useful for determining storage capacity.

A higher power density/specific power allows for faster charge/discharge and mostly related to the "internal resistance" of the cell. A higher energy density/specific energy allows more energy to be stored/extracted, which can result in either increased run-time or smaller/lighter batteries, or a combination of those.

2000 charge/discharge cycles is great. These will be very useful in environments where high charge/discharge rates are key, power tools and electric vehicles. Electronic devices don't have such high current demands, so they'll take a slower route to electronics. Lower internal resistance, fast discharge capacity increase the potential hazard if there is a short. Manufacturing defects or mis-use could result in fire or explosion, so I suspect we'll see lots of caution in deploying these for the first few years.

I think your Xbox will reject anything Sony. Might have to wait until Toshiba, Sanyo, Panasonic, or another manufacturer comes out with these. ;)

Do the math. Take the Volt with it's 8KWh of usable capacity (it's a 16KWh battery, but they only use about 50% for longevity reasons), assuming 20% conversion/charging loss (that's a little high, but if you have to use any power for cooling the battery, it's reasonable), you need 9.6KWh to recharge. 9600W / 120V = 80A (actually, with AC, it's more like 120A). With a 10A/120V supply, that's 8-12hrs. The problem isn't the battery, it's supplying the power from a 120V outlet.

You can use a 20A or 30A circuit to cut that to 3-6 hrs, and you can up it to 240V to cut that in half to 1.5-3 hours. Getting to a 30 minute recharge would require nigher voltages and/or current, and that's for only 8KWh of battery. The Nissan LEAF has 24KWh of battery, it could take 3x as long or 3x the current.

Put another way, I used about 2400KWh of electricity in my house last month. There were ~800 hours in that billing period, so my entire house, which is 100% electric, averaged 3KWh per hour. Recharging a Chevy Volt's 8KWh battery pack in 30 minutes would require approximately 6x my average household electricity consumption for that 30 minutes. I don't know what my peak consumption is, but I would bet it was 9KW or less, so charging the Volt battery in 30 minutes would require 2x my peak household electric usage.

Recharging many electric cars in significantly less than 4 hours will require significant improvements to our electric power distribution network. Maybe we'll have 8-12 hr charging at home, with a 15-30 minute fast charge available, for a premium, at a commercial "charging station". Of course, the safety considerations of having average consumers dealing with the voltages and amperages necessary for that type of fast charging are pretty big.

Follow-up announcement from Sony:

The Sony PlayStation 3 will now be available in a hand held portable model, the PS3P. The PS3P will include a Blu-ray drive, 6" wide-screen OLED, stereo speakers, stereo headphones with mic, HDMI 1.3a output, Wi-Fi connectivity, USB 2.0, Bluetooth 2.0, and a Memory Stick XC slot for storage. Connectivity to the PlayStation Network is possible via Wi-Fi or an optional USB cellular data modem. In addition to the built-in controls, it will be compatible with all PS3 controllers for use when at home.

This innovative new product is possible because it will be powered by Sony's new "Olivine-type" LiFePO4 batteries. The batteries can be recharged in about 30 minutes using the included AC adapter.

For the comfort and safety of the users, the case is made from insulating, heat-resistant plastic, and the system includes two fans for heat dispersal.

Pricing has not yet been announced, but is expected to be under $600. Sony hopes the new portable will stimulate it's sagging video game business by appealing to serious gamers.
