At some level, it doesn't make too much sense to go that much higher in the power (which I'm assuming is the same as discharge rate, since voltage is fixed). Current lipoly batteries are rated at 30C (Amps per watt*hour). Essentially this means that the battery can be fully discharged in a minimum of two minutes. It doesn't seem like there are that many applications that require higher power output.
- baq 13y agocars, for one, especially if high power output correlates with high power input for charging.
- ajross 13y agoExactly. It's very rare to find an application where a rapid discharge matters (battery powered guided missile maybe? A drone launcher that boosts a device to altitude and then comes back down on a parachute?), but a rapid charge speed is almost universally desired. At the numbers being quoted here, for example, it would become faster to simply charge your phone than swap the fiddly battery.
- bencpeters 13y agoAgreed. I would argue that many (most?) higher power applications would be better served by ultracapacitors anyway...
