Already-Impressive Performance of Lithium Ion Cells Dramatically Increased

“The team led by Rice engineer Sibani Lisa Biswal and research scientist Madhuri Thakur reported in Nature’s open access journal Scientific Reports on the creation of a silicon-based anode, the negative electrode of a battery, that easily achieves 600 charge-discharge cycles at 1,000 milliamp hours per gram (mAh/g). This is a significant improvement over the 350 mAh/g capacity of current graphite anodes.”

via Rice team boosts silicon-based batteries.

One of the important lessons I remember from high school physics was scale. By using fluffier particles of silicon, many more lithium ions can be bound to make anodes of lithium-ion batteries. The current technology is already intense turning notebooks into fire-bombs when things go wrong, but OEMs still seek longer battery-life or lighter equipment so this news will be welcomed. I expect it to be fast-tracked into production to prop up Wintel and welcomed in ARMed devices to give ever more performance-hours.
