Actually the latest generation of Li-Polys that are commercially available have some pretty impressive discharge rates. I just bought a Polyquest branded pack that can discharge at 37 amps continuous, and can temporarily provide current in the 49 amp range.
The radio control crowd is eating these up, as the weight to capacity ratio is great, and the discharge rates are reaching NiCad and NiMh levels.
Some of the newer Kokam cells are capable of discharging at 20C, giving some of the larger packs a 50+ amp continuous discharge rate. These come at a price, about $145 for an 11.1V 3200 mAh pack.
