CATL Targets 2027 for Solid-State Battery Production Amid Cost Challenges - Revolutionising Energy Storage

CATL aims for small-scale production of solid-state batteries by 2027, according to a report. Solid-state batteries offer enhanced safety, higher energy density, and improved performance. CATL is focusing on the sulfide option for solid-state batteries, despite challenges related to cost and complex production processes.

According to a report from local media outlet Jiemian, CATL aims to achieve small-scale production of these advanced batteries by 2027. However, the company acknowledges that overcoming cost-related challenges is crucial for realising large-scale production.


The significance of this development lies in the potential of solid-state batteries to address the limitations of conventional lithium-ion batteries. Producers argue that solid-state batteries offer improved safety, higher energy density, enhanced performance, increased durability, and reduced environmental impact. These batteries have the power to revolutionise various industries, including electric vehicles, portable electronics, and renewable energy systems.


CATL's chief scientist, Wu Kai, revealed that the company's current level of research on solid-state batteries stands at 4 on a scale of 1-9 for technical and manufacturing maturity. Wu stated that CATL aims to achieve a rating of 7-8 by 2027, the year when the company plans to commence small-scale production of solid-state batteries.


Here are some key points about solid-state batteries and CATL's approach:


- Solid-state batteries are expected to outperform liquid lithium batteries in terms of energy density. While liquid lithium batteries can reach 350 watt-hours per kilogram, solid-state batteries are projected to achieve up to 500 watt-hours per kilogram, according to Wu Kai.


- CATL is primarily focusing on the sulfide option for solid-state batteries. Wu explained that sulfide electrolytes exhibit high conductivity and good processability. However, they also have drawbacks such as the generation of toxic gases when exposed to water and high costs due to complex production processes.


- CATL aims to capture 1% of the global battery market share with solid-state batteries. The company acknowledges that there are still technical challenges to overcome, including solid-solid interfaces, lithium metal anodes, solid-state electrolytes, and other manufacturing processes.


This announcement from CATL comes in the wake of Japanese automaker Toyota's plan to develop solid-state batteries. Toyota aims to introduce electric vehicles equipped with solid-state batteries to the market as early as 2027, enabling them to travel around 1,200 kilometers on a single charge in under 10 minutes.
