Here's a more recent article on this battery: Japanese Organic Cotton Battery to Revolutionize Electric Vehicles

This article contains a few interesting quotes:
Industry Leaders Magazine said:
The Ryden battery has five advantages over lithium-ions as mentioned above. It can charge 20times faster than lithium-ion batteries. It has over 3,000 charge and discharge cycles, making it extremely dependable. It’s easy to manufacture and doesn’t use any rare metals in the making. The Ryden battery is extremely safe and runs at a steady temperature, reducing the risk of fire and explosion hazards. Finally, the battery is 100% recyclable.

They really do portray this as the Holy Grail of batteries.
Industry Leaders Magazine said:
Not long from now, the Japanese Le Mans auto racing group, Team Taisan, reported its association with PowerJapan Plus to create Ryden batteries for an electric vehicle it hope to race with one day. The first step towards making it possible, they say, is a Ryden-fueled electric go-kart that is presently slated to begin test driving in August. In the PJP-Taisan announcement video, Taisan Team owner Yatsune Chiba says it had long ago attempted to race Tesla electric cars however experienced issues with its batteries overheating.

“We have faced a number of issues with electric vehicle batteries up until now,” says Chiba in the accompanying press announcement. “The Ryden battery from Power Japan Plus is the solution we have been searching for. We will first develop a battery capable of withstanding the rigorous demands of racing, before advancing the technology for use in commercial applications.”

I find it interesting that they use the Tesla battery as the reference that they are working against in the racing arena.

This technology will be interesting to watch to see if it can live up to its promises.

Well, Tesla's batteries aren't good for racing, they are good for holding high amounts of energy. If the dual carbon battery can hold similar amounts of energy while also providing very low internal resistance, then it could definitely be a winner.
 
They also referenced the Tesla Roadster, which uses older, less energy dense LiCo chemistry, and they still refuse to say what their energy density really is. The only specific figure they give is cycle life beyond 3,000, which is great, but other lithium chemistry can claim the same. The charge rate of "20 times faster than lithium ion batteries" is meaningless since some lithium ion chemistry charges much faster than others. Which chemistry are they 20 times faster than? I hope they are for real but they really should provide some relevant data.
 
Besides how do you get 20 times the power of a supercharger connected to the vehicle.
Although if you could supercharge full throttle right to 95+% it would have a marked improvement.

From the article:

"It is also slightly higher than that of the lithium-ion manganese spinel battery used in General Motors’ Volt hybrid and the nickel-manganese-cobalt (NMC) battery reportedly used in Nissan’s all-electric Leaf."

That tells me all I need to know about the "accuracy" of this article. :lol:

Yes, someone pointed that out in the comments.

with all the yahoo on InsideEVs about the future being NMC, I thought I might link to the chemistries that really matter today, and tomorrow
NCA - Tesla
Mn2O4 - Nissan, LG, Mitsubishi, etc

note that LITHIUM MANGANESE NICKEL OXIDE (LMNO) the final cathode material on the neicorp web site, is one of the candidates that NEC - and therefore Nissan is considering
MNO (Ni.5 Mn1.5 O4 aka high voltage spinel) can get equivalent energy density as NCA, but without the raw materials cost, it is also probably safer than both NCA or NMC.

note closer, for Neicorp, LMNO has 50% more capacity than LMO.
 
I generally don't bother posting the latest PR blurb from some lab looking for funding, but am making an exception. Via GCC:
NTU Singapore team develops ultra-fast charging Li-ion battery with new TiO2 gel anode material
Click to expand...
Quoting: "A battery equipped with the new anode material can be recharged up to 70% in only 2 minutes. The new battery will also be able to endure more than 10,000 charging cycles."

We'll see if it can be commercialized.

Which is why I always include a caveat about commercialization. BTW, I see I forgot to include the link, so here it is:

ALEVO OPENS VICTORY INDUSTRIAL PARK IN CONCORD, NORTH CAROLINA

Highlights:
2500-2600 jobs
40 GridBanks / month in production by July 2015 (Each GridBank capable of 2 MW power, 1 MWh storage)
LiFePO4 w/inorganic sulfur electrolyte capable of 40,000 cycles without significant loss of performance.
20 GWh annual capacity by 2018

Looks like Tesla will have some competition in the energy storage market. If these batteries are even half as durable as they claim, they could be huge winners.

Another announcement of new battery, this one claiming cost reductions, a huge increase in energy density, and no thermal management required, and "headed for shop floors in just over a year":

...The new battery does not need (temperature control) systems because it operates safely at a wide range of temperatures, which should shave costs, said Dr Hu, and the battery itself will be about 20 per cent cheaper than existing ones...

Independent experts in the US recently confirmed prototype cells in the battery developed by Dr Hu and Prof Sadoway can store more than twice as much energy as conventional cells.

The main difference between their battery and existing ones is that it has an ultra-thin metal anode with higher energy density than the graphite and silicon anodes in current batteries, and uses safer electrolyte material...To speed up the process of getting the device to market, SolidEnergy only plans to make the core battery materials for larger manufacturers...

I wonder if they are pitching to Nissan right now?

This video claims over 700 Wh/kg and -40 C to 280 C "safe" operating range!

Hope the battery production values are better than those in this video, with its annoyingly loud and overly-dramatic background muzak...
