Rice team boosts silicon-based batteries

[font size=4]‘Crushed’ porous silicon anodes show dramatic increase in charge-discharge cycles [/font]
[font size=3]HOUSTON – (Nov. 1, 2012) – Researchers at Rice University have refined silicon-based lithium-ion technology by literally crushing their previous work to make a high-capacity, long-lived and low-cost anode material with serious commercial potential for rechargeable lithium batteries.
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.
That puts it squarely in the realm of next-generation battery technology competing to lower the cost and extend the range of electric vehicles.
The new work by Rice through the long-running Lockheed Martin Advanced Nanotechnology Center of Excellence at Rice (LANCER) is the next and biggest logical step since the partners began investigating batteries four years ago.
