Nissan to (finally) spend funds on battery technology and hybrids - starting with the following joint venture with NEC:

Nissan-NEC to make lithium-ion batteries
Sunday May 18, 11:09 pm ET
By Yuri Kageyama, AP Business Writer
Nissan-NEC joint venture to invest US$115 million to mass produce lithium-ion batteries
TOKYO (AP) -- Nissan's joint venture with electronics maker NEC Corp. will invest 12 billion yen (US$115 million; euro74 million) to start mass-producing lithium-ion batteries -- a technology widely viewed as key for next-generation green cars.
Nissan Motor Co. Executive Vice President Carlos Tavares told reporters Monday the Japanese automaker wants to be a global leader in "zero-emission vehicles."
Lithium-ion batteries are now more common in laptops and other gadgets, although all the world's automakers are working on applying the batteries for their cars.
Nissan's joint venture called Automotive Energy Supply Corp. plans to make advanced lithium-ion batteries for electric vehicles, hybrids and fuel cells -- all important technology to reduce pollution as well as global warming gases.
"Nissan firmly believes the ultimate solution for sustainable mobility lies in zero-emission vehicles," Tavares said at a Tokyo hotel.
A plant for the batteries, set to be running by 2009, will have annual production capacity of 65,000, and starting capacity of 13,000, Nissan said. The investment will cover three years, it said.
Tokyo-based Nissan has been sometimes criticized as falling behind Japanese rivals such as Toyota Motor Corp. and Honda Motor Co. in ecological technology.
Toyota has a big hit with its gas-electric hybrid, Prius, which has already crossed the 1 million sales mark worldwide. Honda also has its own hybrid and fuel-cell models.
Nissan has said it will introduce an electric vehicle in the U.S. and Japan, as well as its own hybrid, in 2010.
By 2012, Nissan plans to mass-market electric vehicles to consumers globally. It is also planning to make available on a wide scale zero-emission vehicles in Israel and Denmark in 2011.

MIT Tech Review on the state of US manufacturing and battery manufacturing.
http://www.technologyreview.com/read_article.aspx?id=39311&ch=other&nlid=nldly&a=f
| Quote: | Academic researchers have begun documenting the complex connections between innovation and manufacturing with an eye to clarifying how the loss of U.S. manufacturing could affect the emergence of new technologies. Willy Shih, a professor of management at Harvard Business School, has created a list of basic technologies in which the United States has squandered its lead in manufacturing in recent years. They include crystalline silicon wafers, LCDs, power semiconductors for solar cells, and many types of advanced batteries. And he has detailed how losing the "industrial commons"—the research know-how, engineering skills, and manufacturing expertise needed to make a specific technology—can often mean losing the knowledge and incentives to create advances in related technologies. For example, as silicon semiconductor production and associated supply chains have shifted to Asia, the development of new silicon-based solar cells has been hampered in the United States.
It turns out it's not necessarily true that innovative technologies will simply be manufactured elsewhere if it doesn't happen in the United States. According to research by Erica Fuchs, an assistant professor at Carnegie Mellon University, the development of integrated photonics, in which lasers and modulators are squeezed onto a single chip, has been largely abandoned by optoelectronic manufacturers as they have moved production away from the United States. Many telecom firms were forced to seek lower-cost production in East Asia after the industry's collapse in the early 2000s, and differences in manufacturing practices meant that producing integrated photonic chips was not economically viable in those countries. Thus a technology that once appeared to be just a few years away from revolutionizing computers and even biosensors was forsaken. Economists might argue that we don't care where something is produced, says Fuchs, but location can profoundly affect "the products that you choose to make and the technology trajectory itself."
For many people in industry, the connections between innovation and manufacturing are a given—and a reason to worry. "We have learned that without a foothold in manufacturing, the ability to innovate is significantly compromised," says GE's Idelchik. The problem with outsourcing production is not just that you eventually lose your engineering expertise but that "businesses become dependent on someone else's innovation for next-generation products." One repercussion, he says, is that researchers and engineers lose their understanding of the manufacturing process and what it can do: "You can design anything you want, but if no one can manufacture it, who cares?" |

On the Volt, battery coolant not only had to leak, but be allowed to dry completely to crystals, over weeks, to conduct a short of a still powered up battery. Needless-to-say NHTSA did not follow rudimentary safety protocol and drain the frickin' battery. Needless-to-say occupants would have long left their occupancy.
The Volt doesn't need coolant--but then you'd complain you couldn't drive in Detroit or Palm Springs with any range to speak of.
Of course this is now a political hot potato so expect to see issue blown up in all directions. LaHood has already had to come out and declare Volt 'safe.' 
GM looses money on every Volt sold (which is why it's served primarily as an advertising vehicle this last year) so doesn't bother me. They come to look at Volt and leave with a 42mpg Cruze Eco.

Snowbound motorists and electric cars don't mix. Not only do you strand the car (which then has to be towed), you don't keep the heat running waiting for your rescue. Sunny shiny happy people only.

E=mc2 turns battery nodes inside out:
http://www.economist.com/node/17899724
| Code: | | Ironically, today’s most fashionable battery material, lithium, is the third-lightest element in that table—and therefore one for which no such relativistic effects can be expected. And lead is about as heavy as it gets before elements become routinely radioactive and thus inappropriate for all but specialised applications. Still, the search for better batteries is an endless one, and Dr Pyykko’s discovery might prompt some new thinking about what is possible in this and other areas of heavy-element chemistry. |
See "The Myth of Progress" below.

Ford to ship its Focus electric vehicle later this year:
http://www.dailytech.com/article.aspx?newsid=20603
| Quote: | Ford still hasn't provided the official range for the Focus Electric, but all signs point to the vehicle having a maximum range of 100 miles on a charge (identical to the Nissan Leaf). The Focus Electric gets its motivation from a 100 kW electric motor (123hp, 181 lb-ft torque), and a 23-kWh lithium-ion battery pack (developed in conjunction with LG Chem).
You wont be breaking any speed records with the Focus Electric as its top speed is limited to “only” 84 mph.
“Its advanced powertrain will deliver significant energy efficiency advantages and zero CO2 emissions without compromising driving enjoyment,” said Derrick Kuzak, Ford’s group VP for Global Product Development. "And its suite of smart driver information technologies will transform the way customers think about energy usage and their transportation needs.”
Ford wasted no time in its press release taking digs at both Nissan's Leaf and Chevrolet’s Volt. Ford notes that the Focus Electric's 240-volt charger will recharge the battery pack within three to four hours (half time required for the Leaf). Ford also states that the Focus Electric will have a higher mpg equivalent than the Volt. |
