Makers of lithium ion electric-vehicle batteries worldwide are outpacing EV automakers in terms of manufacturing capacity.

This is likely to result in a temporary idleness on the part of some factories by 2013, according to a report released today by Bloomberg New Energy Finance.

The report (only available to BNEF subscribers) shows it's simply a matter of doing the math based on manufacturers' reports and commitments worldwide from both the auto and battery industries.

Automakers are expected to produce roughly 839,000 plug-in EVs worldwide by 2013, which in turn will drive lithium ion EV battery demand to 18 … Read more

Ultrabooks are coming. The first wave of superslim laptops are expected to hit in force by the holiday season. Earlier this week, I spoke with Greg Welch, director of Intel's Ultrabook group, to get a better idea of what an Ultrabook is.

Though Intel won't make Ultrabooks, it will supply the core components, so it is intimately involved in the platform. And, as Welch, describes it, the Ultrabook is "an initiative to advance the state of the art of the notebook experience across several years."

Question: Can you talk about some of the new technologies Intel … Read more

Lithium ion battery company Leyden Energy said today it has raised $20 million to ramp up production of its long-lasting batteries for consumer electronics.

The 4-year-old company said the funding, led by venture capital company New Enterprise Associations, will be used to add manufacturing capacity and build out its sales channels.

Leyden Energy's batteries last week become available from online retailer Dr. Battery, which is offering "Advanced Pro" battery replacements for Acer, Gateway, Lenovo/IBM, Dell, Hewlett-Packard, and Toshiba notebooks.

A conventional battery has between 350 and 400 charge cycles before performance starts degrading. The Leyden Energy … Read more

Like the idea of a fully transparent cell phone, e-reader, or other device?

Stanford University graduate student Yuan Yang has come up with a way to make a see-through lithium ion battery, and it could pave the way for completely see-through flexible electronics (some partially transparent gadgets already exist). Developed in conjunction with Yi Cui, a professor of photon science at the SLAC National Accelerator Laboratory, the battery would cost nearly the same as a regular battery if produced on a mass scale, the creators say.

So how does one make a see-through power source? According to Stanford News, "Yang and Cui devised a mesh-like framework for the battery electrodes, with each 'line' in the grid being approximately 35 microns wide. Light passes through the transparent gaps between the gridlines; because the individual lines are so thin, the entire meshwork area appears transparent." … Read more

Sony has come under investigation as part of a wider probe by the U.S. Department of Justice into the competitive practices of the rechargeable-battery industry, the company revealed in a financial filing today.

Sony Electronics was first contacted in May with a subpoena from the Justice Department's Antitrust Division. A company spokesman told Bloomberg Sony is cooperating with the probe.

"Sony understands that the DOJ is investigating competition in the secondary batteries market. Based on the stage of the proceeding, it is not possible to estimate the amount of loss or range of possible loss, if any, … Read more

Start-up Leyden Energy on Monday is expected to announce a distribution deal for laptop battery cells that improve the life of typical lithium ion batteries.

The Fremont, Calif.-based company will supply cells for replacement batteries to Canadian distributor Dr. Battery, said CEO Aakar Patel last week. The batteries will have a three-year warranty and maintain 80 percent of their capacity after three years, he said.

The 4-year old, venture capital-backed company has not come up with a new type of lithium ion chemistry, but has commercialized an electrolyte technology which Leyden Energy licensed from DuPont, Patel said.

"With … Read more

When a lithium ion battery reaches the point at which it can no longer be used in an electric car, it still has the potential to be used in other applications. But exactly what are the best uses for them?

The U.S. government is backing a comprehensive study to determine just that, the National Renewable Energy Laboratory (NREL) announced Tuesday.

"To date, no one has comprehensively studied the feasibility, durability, and value of Li-ion batteries for second-use applications," NREL said in a statement.

The California Center for Sustainable Energy (CCSE) will lead the research project which will … Read more
