Li-S vs Li-ion batteries: Like when a freshman shows up to prom…and he’s better looking than you.
The short version:
- Li-S (lithium-sulfur) batteries may be the replacement for Li-ion (lithium-ion) batteries.
- The Alise Project has recently announced it has created a new prototype that can deliver 325 Wh/kg. Current Li-Ion batteries would be around 150 Wh/kg.
- The Alise Project has the participation of 16 partners from 5 different countries.
- Researchers say lithium-sulfur technology is still far away from its Wh/kg limits, which is not the case for lithium-ion.
Li-S might still be young, but it’s looking really promising. Less cobalt, more power density, and lots of room for improvements. The Alise Project would like to start production in 2020, but it may be years before we see these batteries in vehicles, motorcycles, and other products. Keep the innovations coming.
