Massive Battery Energy Storage System Project Sparks Controversy

Could solid-state batteries revolutionize energy storage?

The country is now racing with its international rivals, particularly those from Japan and the Republic of Korea, to embrace the next-generation battery technologies. Solid-state batteries, widely regarded as one of the most promising solutions in the coming decade, could revolutionize energy storage.

What is a solid state battery?

Solid-state batteries, using solid electrolytes instead of liquid ones, achieve much higher energy density (up to 500 Wh/kg) than traditional liquid lithium-ion batteries (200-300 Wh/kg). This provides more energy in the same volume and reduces battery size.

What is a solid-state battery (SSB)?

The solid-state battery (SSB) is a novel technology that has a higher specific energy density than conventional batteries. This is possible by replacing the conventional liquid electrolyte inside batteries with a solid electrolyte to bring more benefits and safety.

What is China's target for small-scale production of solid-state batteries?

Chinese battery giants CATL and BYD have set 2027 as their target for small-scale production of solid-state batteries. Scientific teams are intensifying their collaboration with frontline battery companies to accelerate the commercialization of technologies.

What are the benefits of solid-state batteries?

One of the most significant benefits of solid-state batteries is their enhanced safety profile. By eliminating the liquid electrolytes used in traditional batteries, which are prone to leakage and combustion, solid-state batteries significantly reduce the risk of fire and other safety hazards.

What is a solid-state battery roadmap?

Based on an extensive literature review and an in-depth expert consultation process, the roadmap critically evaluates existing research as well as the latest findings and compares the development potential of solid-state batteries over the next ten years with that of established lithium-ion batteries.
