Charge times, safety, and cycle durability are important. Even if direct competition with Li-ion is absurd at this point, the comparison isn't useless as it gives context. For example, if you compare to Lead-acid [1], it has about twice the energy density and is probably less harmful to the environment. Also, 7000 charge cycles is excellent compared to existing types.
