IBM Invests in Lithium-Air Batteries

IBM Research is beginning an ambitious project that it hopes will lead to the commercialization of batteries that store 10 times as much energy as today's within the next five years. The company will partner with U.S. national labs to develop a promising but controversial technology that uses energy-dense but highly flammable lithium metal to react with oxygen in the air. The payoff, says the company, will be a lightweight, powerful, and rechargeable battery for the electrical grid and the electrification of transportation.

Lithium metal-air batteries can store a tremendous amount of energy--in theory, more than 5,000 watt-hours per kilogram. That's more than ten-times as much as today's high-performance lithium-ion batteries, and more than another class of energy-storage devices: fuel cells. Instead of containing a second reactant inside the cell, these batteries react with oxygen in the air that's pulled in as needed, making them lightweight and compact.

"With all foreseeable developments, lithium-ion batteries are only going to get about two times better than they are today," he says. "To really make an impact on transportation and on the grid, you need higher energy density than that." One of the project's goals, says Narayan, is a lightweight 500-mile battery for a family car. The Chevy Volt can go 40 miles before using the gas tank, and Tesla Motors' Model S line can travel up to 300 miles without a recharge.
10 times the energy in the next 5 years sounds good to me. Best of luck to them.

In related news:
The Cleantech Group’s numbers show an uptick in venture-capital funding for batteries in the first quarter, even as overall US venture investments fell to the lowest level since 1997, according to the National Venture Capital Association.

Spurred by federal cash, electric cars, and demand for ever more powerful gadgets, investment in advanced batteries has bucked the recessionary slump and, energy analysts say, could help the economy recover.

Cleantech tracked $94 million in advanced-battery investments in the previous quarter, up substantially from a recession-affected $29 million in the last quarter of 2008 and up slightly from $90 million in the first quarter of that year.
The more battery research the better.

It is inevitable for things of this sort to happen, especially in today's time. Whether you have a large company or not, I think product managers should really take a look into their Product Opportunity Gap (POG) and really see if they can make a difference or not. Many calculations have to be taken into consideration when looking at the company at an All-Around perspective. Judgment's cannot necessarily be made upon feelings rather logic. Being a business man and reading this, I sincerely think a better alternative could be formed. But, if not, then instead of worrying about losing money, unravel some sort of 'secret plan' to your organization to help boost confidence and productivity rate. That's my personal opinion.


Hi ,

Thanks for writing such an interesting article. Its really good to know about the batteries in detail. Seriously do we realize how many things in your house that need batteries? Let’s count it, from the flashlight, cell phone, iPod, cameras, and many more. Knowing it should make us realize on how essential the presence of the batteries in our daily life. However, with that so many kinds of battery, which is generally different between one to another, sometimes we have some difficulties in finding the desired type.

Find the right batteries supplier is not hard if you check out because this website provides the widest selection of batteries and you can choose the right battery based on the categories. You can get the procell batteries which available in several sizes and voltage. You also can find Duracell batteries that divided into duracell plus batteries and duracell ultra batteries. All of the batteries come with cheaper price because this website provides the discount batteries in bulk, wholesale, and retail quantities.
