Are sulfide-based all-solid-state batteries coming to China?

At a conference held by the China Automotive Battery Innovation Alliance late last week, Ouyang Minggao, a renowned battery expert and an academician with the Chinese Academy of Sciences, said that in China, the closest technical route to industrialization is the sulfide-based all-solid-state batteries.

Are Chinese companies ready for a solid-state battery?

Solid-state batteries are sensitive to moisture, so their manufacturers need special equipment to keep humidity away from production lines. While government initiatives should accelerate solid-state battery development, Chinese companies aren’t waiting. Battery makers have already started formulating plans for the next-gen technology.

Should China commercialize all-solid-state batteries before 2035?

Ouyang suggested that instead of producing only samples, China must strive to commercialize all-solid-state batteries with an energy density of more than 400 Wh/kg and 800 Wh/L before 2035.

Is sunwoda ready to mass-produce all-solid-state batteries by 2026?

Battery maker Sunwoda told China Daily that it has finished R&D of its all-solid-state battery with an energy density of more than 400 Wh/kg, and plans to mass-produce it by 2026, with an estimated production capacity of 1 gigawatt-hour. This is also the first time that the company disclosed momentum in its R&D of all-solid-state batteries.

Are automakers making a solid-state battery?

A batch of automakers and battery firms have announced solid progress has been made in that direction. Battery maker Sunwoda told China Daily that it has finished R&D of its all-solid-state battery with an energy density of more than 400 Wh/kg, and plans to mass-produce it by 2026, with an estimated production capacity of 1 gigawatt-hour.

Are solid-state batteries durable?

Durability is the biggest issue with solid-state batteries, however, repeated charging and discharging causes cracks between the battery’s cathodes and anodes and its solid electrolytes also impact its performance. Another hurdle in widescale adoption of solid-state batteries is that mass-producing them is a challenge.
