Stories about: Battery Technology

Nvidia's Tegra system-on-chip will allow portable devices to play high-definition video for more than 10 hours, an engineer from the company told the Hot Chips conference on Monday.

Nissan has unveiled its latest all-electric car prototype, a model based on a new lithium ion battery manufactured by a joint venture it formed with NEC.

The late science fiction author Arthur C. Clarke famously said that "any sufficiently advanced technology is indistinguishable from magic."

Dreams of fuel cells serving the power needs of a laptop PC or other new technology to significantly increase battery life won't likely be available for years, according to an Acer executive.

Fuel cell technology that is currently in development boasts the ability of extracting energy from virtually any sugar source to power portable electronics like cellular phones, laptops, and sensors. The new technology is expected to be biodegradable, environmentally friendly and more energy efficient than current options, providing a green alternative to current Lithium-ion batteries.

3M has filed suit against several big electronics companies, including Sony and Lenovo Group, for allegedly violating two patents related to lithium-ion battery technology.

Environmentalists have been urging consumers for decades to wake up to impending disaster and change their buying, driving and living habits to reduce pollution, cut energy consumption and help reverse global warming.

IBM and Lenovo Group has recalled 526,000 Sony batteries for ThinkPad notebooks, becoming the latest vendors to act on fire-prone power sources.

Dell just announced the largest recall of any consumer electronic item in history: 4.1 million lithium-ion batteries manufactured by Sony and used in over 30 of its models. The recall was precipitated by a small number of overheated batteries in notebooks getting hot enough to cause a fire or potentially explode. Although the risk of such mishaps is small, Dell did the right thing for its customers and itself by taking no chances on someone getting hurt (or worse).
