Farasis Energy, a Chinese battery manufacturer listed on the Shanghai Stock Exchange Star Market, is making significant strides in the development of solid-state batteries. By the end of 2025, the company aims to complete the construction of a pilot production line for sulfide-based solid-state batteries with a capacity of 0.2 GWh.
This pilot production line is a crucial step towards the commercial-scale manufacturing of solid-state batteries, which Farasis Energy plans to achieve by 2026. The company targets scaling up production to the gigawatt-hour (GWh) level, with energy densities exceeding 400 Wh/kg, approximately 50% higher than current lithium-ion cells.
One of the key strategic partners for Farasis Energy is Mercedes-Benz, due to their investment relationship. The company expects to deliver 60Ah sulfide solid-state battery samples to Mercedes-Benz for testing and validation, with these initial samples being delivered primarily by late 2025.
Beyond Mercedes-Benz, other Chinese automakers like Changan Automobile have been mentioned in the industry context, although it is unclear whether they are directly partnered with Farasis Energy.
Farasis Energy's solid-state batteries incorporate advanced features such as high-nickel cathodes, lithium-metal or silicon-rich anodes, stacked cell architectures, and soft-pack designs for thermal management and packaging efficiency. The company anticipates expanding sample deliveries to additional clients as it moves towards commercial-scale production.
Notably, Farasis Energy's solid-state electrolytes have passed puncture, shear, and thermal chamber tests, demonstrating their robustness and suitability for automotive applications. The company is also renowned for its high-performance ternary soft-pack lithium-ion batteries and collaborates with FAW on commercial vehicle applications.
Farasis Energy has received interest from several established new energy vehicle manufacturers beyond its existing partners. The company is producing solid-state batteries in China and ranks first in domestic soft-pack battery shipments for seven consecutive years (2017-2023).
The company's solid-state batteries are currently being used in Mercedes-Benz's electric vehicles, such as the EQE and EQS, directly from its plants in China. Farasis Energy's aggressive push towards solid-state battery production is expected to pave the way for wider automotive adoption of this technology in the near future.
Scientists at Farasis Energy are collaborating with Mercedes-Benz through their investment relationship to test and validate 60Ah sulfide solid-state battery samples, aiming to incorporate this technology into their electric vehicles. To achieve commercial-scale manufacturing of solid-state batteries by 2026, Farasis Energy is seeking to scale up production to the gigawatt-hour (GWh) level and partner with other tech companies in the field, including those in China like Changan Automobile.
