LG Chem to provide batteries to Japan's Softbank Mobile

By Nam Kwang-sik SEOUL, Aug. 21 (Yonhap) -- LG Chem Ltd., the world's largest lithium-ion battery maker, said Wednesday that it has signed a deal with Japan's second-largest mobile carrier to provide batteries starting this month. LG Chem said the batteries will be used as uninterrupted power supply (UPS) in 130,000 base stations of Softbank Mobile Corp. The UPS is an electrical apparatus that provides emergency power to base stations when the input power fails.

Probe report links lithium battery cargo to 2010 crash of UPS plane outside Dubai

DUBAI, United Arab Emirates - A fast-moving fire that began in cargo containing lithium batteries turned the inside of a United Parcel Service plane into a "catastrophic" chain reaction of flames and smoke before a crash three years ago in the desert outside Dubai, according to a report released Wednesday. The 322-page investigation into the crash, which killed both pilots, backed up preliminary probes pointing to the lithium batteries as the possible cause of the blaze and drew further attention to the potential risks of the batteries in aviation.

Honeywell, maker of 787's emergency transmitter, joining UK fire probe

Honeywell said Monday that it has joined the investigation into last week's fire on a 787 at London's Heathrow Airport amid reports that investigators are eyeing whether its emergency transmitter played a role in the incident. The emergency location transmitter sends a signal with the plane's location if it's involved in a crash. It's meant to help rescuers find the plane.

Factbox: Lithium manganese battery in focus in Boeing probe

(Reuters) - Investigators searching for the cause of a fire on a Boeing Co <BA.N> Dreamliner in London last week are looking at the battery in an emergency locator transmitter built by Honeywell International Inc <HON.N>, a source familiar with the probe told Reuters on Monday. That device is powered by a lithium manganese battery, a long-life battery that has been around for decades and used widely in the military as well as products like digital cameras, walkie-talkies and pacemakers.

U.S. safety firm bolsters battery standards after Boeing crisis

By Deepa Seetharaman DETROIT (Reuters) - Underwriters Laboratories, a 119-year-old U.S. company that develops product safety tests, is strengthening its lithium-ion battery standards after a string of high-profile battery failures that shed light on the technology's weak spots. Those vulnerabilities were highlighted this year when regulators grounded Boeing Co.'s <BA.N> 787 Dreamliner for nearly four months after lithium-ion batteries overheated on two separate jets in January, leading to a fire in one.

lithium ion battery-new technology

SEOUL, May 24 (Yonhap) -- A group of South Korean scientists has developed a new technology that can triple the efficiency and capacity of lithium-ion batteries, the science ministry said Friday. The team, led by Prof. Hyun Taek-hwan of Seoul National University, said the capacity of a lithium-ion battery increased by up to three times when they used a nano structure of iron oxide and manganese oxide, instead of lead, as the cathode of the battery.

Boeing sees 787 battery fixes done by mid-May

Boeing voiced confidence Wednesday that all Boeing 787 Dreamliner aircraft, grounded worldwide for overheated lithium-ion batteries, will have a company fix installed by mid-May. "We have pretty big confidence we can be done with this in a few weeks, by mid-May," Jim McNerney, Boeing chairman, president and chief executive, said in a conference call after the company reported first-quarter earnings. Airlines have begun installing the modifications to the pioneering lithium-ion battery system after the US Federal Aviation Administration approved the Boeing fix last Friday.

Too soon to say if 787 battery issues were design error - Boeing

WASHINGTON (Reuters) - A top Boeing Co <BA.N> executive said on Tuesday it was too early to determine whether problems with the lithium ion batteries on its new 787 Dreamliner that led to the plane's grounding in January stemmed from a design error or some manufacturing problem. Mike Sinnett, Boeing's chief 787 engineer, told an investigative hearing of the National Transportation Safety Board that the batteries had been through thousands of hours of testing before the new airliner began flying, plus additional hours during flight testing.

Boeing says it thought 787 battery short would not lead to fire

WASHINGTON (Reuters) - Boeing Co <BA.N> said on Tuesday that it did not believe during design and testing that a fire could occur in the lithium-ion battery system that failed on its 787 Dreamliner. Under questioning at an investigative hearing by the National Transportation Safety Board in Washington, Mike Sinnett, Boeing's chief 787 engineer, said: "Any form of internal short circuit could lead to venting of that cell and release of electrolyte, but nothing more than that."

U.S. safety board seeks larger lesson in Boeing 787 battery fire

By Alwyn Scott and Andrea Shalal-Esa WASHINGTON/NEW YORK (Reuters) - The top U.S. transportation safety agency is looking beyond what caused a Boeing Co <BA.N> Dreamliner battery to fail in January at larger lessons that can be applied to the airplane certification process and new technologies.
