Farasis Energy, a lithium-ion battery and energy storage solutions developer, has reached a groundbreaking milestone with the successful real-world testing of its innovative battery cells. These cells, projected to last a million miles over 15 years, promise to revolutionize consumer and commercial applications by retaining over 70% of their capacity. While an impressive driving range on a single charge is crucial, achieving a million miles of reliable performance is equally vital.
How did Farasis Energy test a million-mile battery technology?
Farasis Energy tested its million-mile battery using an extensive and rigorous process to ensure long-term durability and performance. The testing involved several key steps:
Accelerated Cycle Testing: The battery cells were cycled over 5000 times, simulating the wear and tear equivalent to a million miles. This accelerated testing, lasting 24 to 36 months, ensures the battery can handle prolonged use.
Environmental Testing: The cells were exposed to various temperatures (25 to 35℃) to mimic conditions in major automotive markets like the coastal United States, Western Europe, and China. Humidity and pressure variations were also tested.
Real-World Simulations: To ensure durability, the batteries underwent mechanical stress tests, including impacts and vibrations. Fast charging and high depth of discharge scenarios were included to test performance under strenuous conditions.
Chemical Stability and Safety Testing: The chemical interactions within the cells were monitored, and materials were tested for long-term stability. Safety features, such as thermal management and propagation prevention, were rigorously evaluated.
Data Collection and Analysis: Continuous monitoring and data logging allowed for detailed battery performance analysis, while modeling and simulation predicted long-term behavior.
By combining these methods, Farasis Energy ensured their battery could meet the demanding requirements of a million-mile lifespan.

Farasis Energy technology
The long cycle life of these cells is achieved through advanced materials and charging strategies. Semi-solid gel-coated separators reduce electrolyte amounts, ensuring excellent ion conductivity and chemical stability. The cathode and anode materials exhibit excellent stability, and the electrolyte and electrode interface are optimized for improved performance. Charging strategies are designed to minimize lithium plating and heat generation, effectively suppressing capacity loss.
These cells offer long life, high energy density, fast charging capabilities, and thermal propagation mitigation. With an energy density of up to 285 Wh/kg, the cells provide additional range for heavy-duty trucks compared to LFP-based battery packs. Farasis Energy's unique packaging technologies, including a directional exhaust system and multisided thermal barrier protection, ensure safe operation by preventing the spread of thermal propagation.
"Farasis Energy is proud to announce the successful testing of our P75 and P73 cells, which have demonstrated exceptional longevity and performance," said the company spokesperson. "These cells represent a significant advancement in battery technology, offering unparalleled benefits for both consumer and commercial applications."
Commercial vehicle applications
Commercial vehicles, such as buses and heavy-duty trucks, can significantly benefit from these long-lasting battery packs, providing financial and environmental advantages. Furthermore, top players in the electric vehicle takeoff and landing (eVToL) market have independently evaluated and chosen Farasis Energy’s pouch cells for their longevity and performance, making them a preferred choice over cylindrical and prismatic cells.
Farasis Energy's advancements in battery technology highlight the critical need for improved battery density and durability, especially for commercial applications where charging infrastructure may be limited. High-energy density batteries like the ones announced by Farasis Energy could provide the extended range and reliability necessary for heavy-duty trucks, buses, and other commercial vehicles that often operate in remote areas without easy access to charging stations.
As the demand for sustainable transportation grows, innovations in battery technology will be paramount in ensuring that EVs can meet the rigorous demands of commercial operations, ultimately leading to lower operating costs and significant environmental benefits. Companies like Farasis Energy are setting a benchmark for the industry, driving forward the future of electromobility and making a significant impact on the broader adoption of EVs in various sectors.
