New Tech claims 10K battery charge cycles/20 yrs lifespan

[macribs]

We are living in exciting times my fellow e-geeks.
Are we seeing the gateway to the new revolution in mass transportation?
If this is for real imagine how that will change the scene? Even more power packed into smaller packages.
Charge time on par with refueling your regular stinky car.

Well they got big words....

Summary:

Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes.

The new generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.

This breakthrough has a wide-ranging impact on all industries, especially for electric vehicles, where consumers are put off by the long recharge times and its limited battery life.

With this new technology by NTU, drivers of electric vehicles could save tens of thousands on battery replacement costs and can recharge their cars in just a matter of minutes.

Commonly used in mobile phones, tablets, and in electric vehicles, rechargeable lithium-ion batteries usually last about 500 recharge cycles. This is equivalent to two to three years of typical use, with each cycle taking about two hours for the battery to be fully charged.

In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide.

Titanium dioxide is an abundant, cheap and safe material found in soil. It is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays.

Easy to manufacture

According to Frost & Sullivan, a leading growth-consulting firm, the global market of rechargeable lithium-ion batteries is projected to be worth US$23.4 billion in 2016.

Lithium-ion batteries usually use additives to bind the electrodes to the anode, which affects the speed in which electrons and ions can transfer in and out of the batteries.

However, Prof Chen’s new cross-linked titanium dioxide nanotube-based electrodes eliminates the need for these additives and can pack more energy into the same amount of space.

Manufacturing this new nanotube gel is very easy. Titanium dioxide and sodium hydroxide are mixed together and stirred under a certain temperature so battery manufacturers will find it easy to integrate the new gel into their current production processes.

One company have already signed up for license....world domination?

Imagine getting 70% charge in 2 minutes. Faster then your stinking ICE car can fill their gas tank.
Let us hope this is not vapor ware and that we in fact do see it to market in two years time as they estimate.

And imagine what we could do with e-bikes.And no range anxiety whatsoever.

I remember seeing this exact 'breakthrough' about 2 years ago...did you check the date on the PR?
Or did they run out of funding now after 2 years and need more and so had another 'breakthough'.
This reminds me of A123 having a breakthrough right before going bankrupt.

I am charging my 2.3KW pack at 2800 watts and it takes me over 30 minutes.

To charge at 2800 watts I needed to install a 220 volt outlet.

You would need a massive electrical line run to your house to charge that fast.

My lithium batteries I bought a couple years ago are starting to age. What stinks is I pretty much have to buy the same exact technology I bought 2 years ago.

I'm predicting we won't see any advancements until 10+ more years that are actually out on the market.

5C charge rate on lipo is quite common already.. if you took a not-quite-empty pack and zap it to 70% at 5C, 5 minutes is about right.

Exactly, charge rates are not really an issue it is capacity, density, weight.
