Farasis expands fourth-gen. EV battery development

Farasis Energy says it is expanding its fourth generation of battery cells for e-vehicles with an “ultra-high power variant” that achieves a fast charging time of fewer than 15 minutes – while maintaining a high energy density of 300 Wh/kg, the company says. This variant has been undergoing external testing by customers and will be ready for industrial production in 2025.

“For a long time, manufacturers focused on the range when developing battery cells,” says Dr. Keith Kepler, CTO, and co-founder of Farasis Energy. “The goal was to come close to the ranges of combustion engine vehicles. In this respect, we have been able to make tremendous progress in recent years.” For example, Farasis’ Generation 1 cells currently in use have an energy density of 285 Wh/kg. Depending on the size of the battery, more than 700 kilometers of range can be achieved with these cells.

The Generation 4 ultra-high power variant from Farasis has increased energy density compared to previous cell generations and also has an improvement in fast-charging time. With this variant, the focus can be placed more on range or more on fast charging capability, depending on the customer’s requirements. In less than 15 minutes, the battery can be charged from 10 to 80% in fast charge mode, the company says. The time to get an additional range of 250 kilometers (approx. 155 miles) through fast charging can be less than eight minutes, the company adds.

An additional aspect of the fourth cell generation, Farasis says, is that they can be fully charged and discharged around 1,500 times.

Farasis is now preparing for industrial production, which will be ready for 2025.
