Neat! I don't think the article mentions energy density. They do have numbers based on current, 175.5 mAh/g and 120 mAh/g, and a voltage of 1.1 V. If I'm mathing the correct numbers:

175.5mAh/g × 1.1V × 1W/1000mW × 1000g/1kg = 193.05 Wh/kg

Wikipedia says lithium ion is 160-300 Wh/kg, so not too bad!

The other end of the range, 120 mAh/g works out to 132 Wh/kg
