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.

Are all-solid-state batteries coming to China?

Since the second quarter of this year, the development of all-solid-state batteries has accelerated in China. A batch of automakers and battery firms have announced solid progress has been made in that direction.

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.

What is the energy density of a solid-state battery?

CATL’s prototype solid-state batteries have an impressive energy density of 500 Wh/kg, a 40 percent improvement over current lithium-ion batteries that typically reach 350 Wh/kg. CATL is developing solid-state batteries using a promising technology called the sulfide route. (Representational image)

Are solid-state batteries a problem?

Despite recent advancements, solid-state batteries are still a work in progress and pose several challenges. 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.

When will a solid-state battery come out?

CATL wants to start small-scale production of solid-state batteries by 2027. Around the same time, Japanese automakers, who have been very vocal about solid-state batteries for years, will also step into the race.
