Sony Announces Targets For Its High-Capacity Lithium Sulfur Battery
According to Japanese reports, Sony set a target to commercialize higher energy dense lithium-sulfur batteries by 2020 to replace current lithium-ion batteries.
Two types are on the table: lithium-sulfur (Li-S) and magnesium-sulfur (Mg-S).
Roughly 40% energy density per volume improvement from 700Wh/L to 1,000Wh/L was mentioned.
At first, the new batteries could be used in smartphones, so possibly EVs will not get them in this decade (if ever), especially since the cells aren’t near ready yet, and cost is still the primary determining factor in vehicle applications.
