A more serious report http://www.gizmag.com/silicon-anode-performance-batteries/40058/
"Graphite has served the lithium-ion battery world as material for negative electrodes well so far, but also presents something of a roadblock for improved capacity. This is due to the relatively small amount of energy it can store, which comes in at around 370 mAh/g (milliamp hours per gram). Silicon has become an increasingly popular substitute for battery researchers looking to up the ante, with a specific capacity of 4,200 mAh/g. However, it isn't without its limitations either. "

But only  a modest increse
"They also claim the design led to a capacity of more than 1,000 mAh/g over 2,275 cycles (a marked improvement on graphite's average of 500) and a Coulombic efficiency of 99.9 percent, which pertains to the charge transferred to and from the electrode and has been seen as another weakness of silicon anodes.
The researchers say the new anode can bring about a 40 to 60 percent increase in energy density of lithium ion batteries and could see electric cars driven up to 500 km (310 mi) per charge. They plan on commercializing the technology and, quite promisingly, expect to see it incorporated into new batteries within the next year."

If we are doing better on the mAh/g then we may have the product to beat. Has anyone seen any specs on our silicone?
