Altairnano Launches Application Kit to Increase Adoption of Its Lithium-Titanate Battery Technology

Altair Nanotechnologies, Inc. released an Application Kit designed to give original equipment manufacturers (OEMs) the ability to apply its advanced lithium-titanate battery systems in a test environment simulating real-world operating conditions.

The Application Kit includes Altairnano’s 24 volt, 50 Ah battery module, a connection and control unit (CCU) including a battery management system, and a NetBook computer configured to control and monitor the system performance. The system is scalable to test battery modules in different voltage and amperage configurations.

According to Terry Copeland, Altairnano President and CEO, the release of the Application Kit is a critical element of the company’s strategy to demonstrate the value of the technology for OEMs.

I still love the lithium titanate chemistry, but it's density continues to lag, with Toshiba now at 100wh/kg and hoping for 150wh/kg whilst Panasonic is hitting 270wh/kg

You can't beat it for cold climates or durability though.

On the subject of energy density, has anyone else seen this?

http://www.autocar.co.uk/News/NewsArticle/AllCars/251872/

Martin Eberhard, previously at Tesla now heading VW's EV programme, says that by 2020 VW will have 500 mile range EVs.

He says VW are now working with 18650 LiIon cells (just like Tesla) because of the cost and energy density advantages.

They are expecting to receive Panasonic's 270 Wh/kg cells for the Audi E-tron and VW E-up soon, which will almost double electric range for the same size of battery.

It is also interesting that he quotes 200 Euros per kWh (~$250/kWh) as the price they are buying their 18650s for. Bargain I'd say compared to the other formats.

Clett, I read such an article and have often wondered:

How does one make thousands of 18650 cells into an economical battery? Is there an automation that makes 2X thousands of connections cheap? Same for individual cell monitoring?

Replacing 2.9 Ah cells with the new 3.4 Ah should be a immediate 17% range gain. If true, great to hear 2X capacity is actually in the production pipeline.

Curious, why not scale a 18650 cell to thermos bottle size and then only need a dozen of them and their support circuits for EVs?

The form factor is usually determined by volume application. In this case laptop computers and mobile devices. Until EV battery demands make rescaling 18650 cells economical - we won't see it.

"The form factor is usually determined by volume application."

Ok, flashlight size, several for each of the 20 million China e-bikes produced annually and several dozen for EV's.

Good points Clett: The days of Laptop batteries for EVs will be over when EV market goes up (over one million EVs per year). That will justify more appropriate (larger) standardized formats.

It would be beneficial to have plug-in battery modules (2 Kwh to 5 Kwh) each. Future BEVs and PHEVs could be built with up to 12 modules slots. Electrified vehicle buyers could have the option to buy as many modules as they need or can afford. One could start with as few as 3 modules or so and add more latter when the price is down and performance is up.

That could be too common sense for GM but it could certainly promote the sales of PHEVs and BEVs. It is not an impossible technical challenge.

Scaling LiCoO2 cell size up amplifies the chemistry's thermal stability problems.

"We'll be looking at a commodity price of about 200 euro/kWh" is a not quite the same as "we are paying......". And of course he ignores the much higher costs for assembly, testing, thermal management, etc. Classic Eberhard. I don't know of any car company other than Tesla using LiCoO2 18650s, and even Tesla went to lithium nickel, but Martin soldiers on.

Also, his "we were using 1.4 Ah five years ago" is crap. Here's a Tesla blog from 4 years ago which says their cells were 2.2 Ah. I think even the old Tzero cells were 2.0 Ah.

Volt and Leaf appear to be the only marketed large format battery packs so far. But with the activity in this area growing and highly competitive - we can expect to see some dramatic changes in the next ten years.

Good for electrification.
