“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.”
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.
