Will Prowse reviewed some. They have a very wide voltage range.
- cheaper and ever more abundant inputs
- significantly lower thermal runaway problems
- much higher theoretical kW/kg (but worse kWh/m3)
- much higher cycle life
People are probably oversimplifying some costs (like 10-20$/kwh material costs) while at the same time underestimating the fact that if it can be delivered internationally at < 60$/kwh in the long run, it is a win for energy storage.
For some reasons I have never seen LFP in storage projects going below 200-300$/kwh all costs considered even though cell/pack costs claim in China have always been 50-60$/kwh
i assume you'd always need ventilation, because if it is enclosed, the produced heat will just accumulate and go above 70c eventually.
But ventilation is much cheaper than heating/cooling (and can be a passive vent rather than anything active - thus taking zero power to run except for maintenance/replacement).
