...senior in high school, Kay Redfield Jamison spent her days contemplating killing herself. At age 28, after years of debilitating depression, she overdosed on lithium in a suicide attempt that landed her in a coma. Last night, Jamison, now a Johns Hopkins Medical School psychiatry professor specializing in bipolar disorder, reflected on her own struggles with manic depression. She told a crowd of mostly students that the widespread reluctance to come forward with mental health issues is a major public health problem. “Such privacy and reticence can kill,” she said, noting that many people...
...think GM has an eco-friendly gene in its body. But at the Detroit auto show on Sunday, GM touted a new plug-in electric concept car called the Chevrolet Volt. A lithium ion battery pack powers the car and a three-cylinder engine can recharge the batteries, extending the vehicle's driving range up to 640 miles. The engine also runs on E85 ethanol, getting fuel economy up to 150 miles per gallon - and conceivably eliminating the need for gasoline almost entirely. All in all, it would be a quantum leap over GM's last electric...
...saving bits of energy and environment here and there add up, then Finland's Enfucell has a battery that will help people make a difference by cutting down on all the metal, lithium and alkaline that leaks from conventional cells. "Our battery doesn't have to go to the battery-recycle bin. It's disposable as household waste," says Jaako Happonen, 50, Enfucell's chief executive.

...ordinary "button" batteries (like the one in your watch) and "finger" batteries (think AA). Ions travel from an anode, pass through a solution called an electrolyte to a cathode and emerge as an electrical charge. Instead of running ions through metal casings full of toxic and corrosive substances like lithium and alkaline, Enfucell uses a thin paper sheet as a conduit. It pastes one side with zinc and the other side with manganese dioxide. Ions flow through an electrolyte solution of water and zinc chloride within the paper...
Correction Appended: November 21, 2006 Burning batteries are two words that Sony CEO Sir Howard Stringer would never like to hear again. Before reports surfaced in August that Sony-made lithium-ion batteries had an occasional tendency to fry Apple, Dell and other laptops, the boss of the sprawling Japanese media conglomerate was having a great year. For four quarters, Sony had beaten financial expectations (though it wasn't always profitable). The firm was leaner, following more than 10,000 job cuts and the closure of nine factories. The consumer-electronics division was back in the black. And the movie...
