[h=2]New Lithium Ion Batteries Charge 70 Percent in 2 Minutes[/h] October 16th, 2014 Via: cNet:
The freedom to hold computers in our hands, pop wireless headphones in our ears and pilot drones through our backyards is all brought to us by batteries — especially rechargeable lithium ion batteries. The portable powerhouses are a critical component of our march toward tech mobility, yet most require hours of being plugged in to wall outlets to achieve a full charge.
A brand-new kind of battery to come out of the labs of scientists at Singapore’s Nanyang Technological University (NTU) is set to change that. They’ve created a lithium ion battery that can get up to a 70 percent charge in just 2 minutes and can allegedly last up to 20 years.
The difference between their battery and the standard lithium ion type has to do with the substance used for the anode — the negative terminal.
Current lithium ion batteries have graphite anodes. Instead of graphite, the team at NTU used a titanium dioxide gel they developed that dramatically speeds up the chemical reaction that takes place in the battery, meaning it can charge much faster.

May be interesting if ever applied to vaping

The new battery technologies are definitely on the way. When they hit the 18xxx format, we will benefit from the new tech. After that, we will see tubes and boxy formats change to flat and stealth friendly shapes. It's the battery that contributes most to the size of the mod.

If I can remember when I read the article the safety aspect is what caught my eye. The tech will get there and sooner rather than later. The "green" car thing is off to the races which benefit us.

Advances in battery technology will also benefit photo voltaic power for homes making it more practical to store power for use at night.

Heck, I can see Tesla jumping on the back of that beast all the way to automobile godship. Come one, batteries that get to 70% in under 2 minutes, add in their supercharging station, and I can see full battery in about 20.

"The new battery will be able to endure more than 10,000 charging cycles -- 20 times more than the current 500 cycles of today's batteries"

That'd fix two of the biggest problems with electric cars... Replacing the batteries after their usable life is REALLY expensive, and charging takes too long.
For us it means we could use fairly small batteries with PCCs that keep them charged for a stealth vape, our mods will only rarely need battery replacements, the ego styles will need less replacements, heck...we can get even more creative with designing mods! I only hope that they manage to maintain the safety of our IMR batteries with this new anode design.

"NTU researchers used a new gel material made from titanium dioxide for the anode, instead of the traditional graphite material used in most lithium-ion batteries. Titanium dioxide is safe to use, cheap, and easy to get from the soil. The material is currently used as a food additive or mixed into sunscreen lotions to absorb ultraviolet rays."

...

"Having anodes composed of titanium dioxide instead of graphite also improves the reliability and safety of lithium-ion batteries. In certain cases, lithium can work its way out of solution and deposit on the graphite anodes, causing a dangerous chain reaction known as thermal runaway. “Every type of test we’ve conducted on titanium anodes has shown them to be exceptionally safe,” Chamberlain said.

I made a boo-boo. Moved (final time, I promise) to Batteries and Chargers.

Hell, im waiting to see car batteries the size of pop-tarts.... it's gonna happen some day

The little battery in my LG G3 phone is 3000mah li-ion. You'd think that a flat pack battery such as that would be great for square mods like the iStick and MVP styles. The large flat surface lends itself well to a heat sink for more resilience to high current.

Did you read the comments on that article? The authors assumptions are all refuted by a recycling company executive.

until i can buy one, it doesn't exist

whats this all about? 99% charge in 30 mins? on a SONY VTC??

Sony Global - Sony Launches High-power, Long-life Lithium Ion Secondary Battery Using Olivine-type Lithium Iron Ph

im guessing the product never came to fruition being that its from 2009

The large flat surface lends itself well to a heat sink for more resilience to high current.

while this may seem blatantly obvious, the active cooling that would be necessary to keep the actual components of the cell cool enough to over work the battery safely would take massive amounts of space. there's a lot of insulation to penetrate in a high output lithium cell. i've already posted this pic today, but it's appropriate here too. this is a 5000mah 40c/80c 2s pack...

that foil pouch won't exactly dissipate heat very efficiently. the metal plates are held in place by tape that would act as an insulator... and the entire working inside is one insulating layer over another, repeat ad nauseum. there's just no way that passive external cooling could possibly aid in avoiding possible disaster in the center of the cell.
