LG Energy Solution has set a goal to develop lithium-sulfur battery within the next three years, TheElec has learned.

This means the company is aiming to commercialize the battery sometime in 2027.

Lithium-sulfur battery is one of many battery technologies that could possibly replace lithium-ion batteries in the future.

It has superior energy density of around 2x. This means electric vehicles with lithium-sulfur batteries will be able to double their driving distance while carrying the same weight of batteries.

However, LG Energy Solution is planning to apply the new battery in the aerospace sector first.

This is because airplanes require lighter and more energy-dense batteries compared to ground vehicles.

Lithium-sulfur batteries are also more resistant to lower temperatures compared to lithium-ion batteries.

Lithium-sulfur batteries use sulfur carbon materials as their cathode and lithium metal for the anode.

As it doesn’t use nickel, cobalt, and other heavy metals, they are lighter.

The current challenge is that their life span is shorter and that sulfur has low electrical conductivity. Lithium-sulfur batteries will also need to use more electrolytes.
