The introduction of Silatronix OS3 has seen the battery cells achieve an industry leading energy density of 450-Wh/Kg and 1150-Wh/L, which is among the highest of any commercial lithium-ion cell in the world. Amprius battery cells achieves this level of energy density by applying their proprietary Si-Nanowire platform, which utilizes 100% silicon in the anode.

“The collaboration between Amprius and Koura on this project has been a partnership which has resulted in outstanding performance of our battery cells, even in challenging environments,” said Ronnie Tao, Vice President of Business Development for Amprius. “Using Silatronix OS3 has helped Amprius achieve the highest energy density of any commercial lithium-ion battery cell in the world.”

Additionally, engineers at Amprius collaborated with Orbia Fluorinated Solutions to optimize high-performance electrolyte containing OS3, enabling the cells to operate with long cycle life in challenging environmental conditions.

Advanced electrolyte materials such as OS3 are a critical component of increasing energy density in lithium-ion batteries, working together with advanced electrode technologies such as Amprius Si-Nanowire.

Dr Miki Oljaca, Head of Growth and Technology at Koura, commented: “This application of OS3 represents a significant advancement in lithium-ion electrolyte performance and capability and serves as market validation for the benefit OS3 provides in high-performance lithium-ion cells. The energy density that Amprius achieves in these cells is far beyond anything else commercially available,” added Dr Oljaca. “OS3 delivers stability in the most challenging electrolyte applications, and we are excited to see Amprius apply it in their commercial cells to achieve such high performance.”

Orbia’s Fluorinated Solutions brand Koura is a fully integrated fluorine technology company currently executing on a strategy to accelerate technology development in the rapidly expanding lithium-ion battery industry. Having recently announced the launch of Koflyte® electrolyte additives and co-solvents products developed to improve performance and safety of the next generation of Li-ion batteries in the support of a renewable future.
