The corporate is speaking about an vitality density of as much as 450Wh/kg for its solid-state battery referred to as Solstice. This could enhance the vary of electrical automobiles by as much as 80 per cent, whereas on the similar time ‘considerably decreasing’ the automobile weight and rising automobile effectivity, in response to a press launch. Mercedes is described by Factorial as a ‘key buyer’.
One factor is evident: the solid-state battery includes a new sort of dry cathode design for extra environment friendly and sustainable manufacturing. As is well-known, many battery specialists are at the moment engaged on dry coating processes to simplify manufacturing. Factorial states that by integrating dry cathodes, Solstice might scale back working prices, vitality consumption and the environmental affect of manufacturing.
Basically, Solstice enhances Factorial’s FEST (Factorial Electrolyte System Expertise) platform for automotive and different e-mobility purposes. However that’s not all: Factorial additionally desires to place the brand new solid-state battery expertise within the client electronics sector.
The builders describe a sulphide-based stable electrolyte as a key function of Solstice, which is meant to make sure that batteries stay steady even at working temperatures of over 90 °C. That is stated to have the potential to cut back the necessities of the cooling system throughout the battery pack. This has the potential to cut back the calls for on the cooling system throughout the battery pack, thereby reducing the general price of the automobile.
“Solstice embodies our staff’s expertise management and the potential of solid-state batteries to deal with essentially the most vital hurdles for electrical automobile adoption,” stated Siyu Huang, CEO and co-founder of Factorial. “Solstice not solely will improve the vary and efficiency of electrical automobiles but in addition aligns with our imaginative and prescient for a extra sustainable future. We’re grateful to have Mercedes-Benz’s continued assist, which underscores our potential to fulfill the wants of world automakers now and sooner or later.”
Markus Schäfer, Chief Expertise Officer and Member of the Board of Administration of Mercedes-Benz Group AG, added: “The Solstice solid-state battery expertise represents one other landmark milestone in our partnership with Factorial, which is a cornerstone of Mercedes-Benz’s technique and dedication to main the cost in battery growth. Solstice provides additional enhancements in vitality density and security options that may assist us develop electrical automobiles that set new requirements in vary, price, and efficiency.”
The announcement follows the supply of B-samples of the solid-state battery cells to Mercedes-Benz. The automotive group entered right into a joint growth settlement with Factorial in 2021 and led an funding spherical totalling USD 200 million for Factorial in 2022. Stellantis additionally participated within the spherical on the time. There’s additionally a growth settlement with Hyundai-Kia.
