The introduction of Silatronix OS3 has enabled the battery cells to achieve peak 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 achieve this level of energy density by applying their proprietary Si-Nanowire platform, which uses 100% silicon in the anode.

“The collaboration between Amprius and Koura on this project has been a partnership that has resulted in exceptional performance from our battery cells, even in harsh 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, Amprius engineers collaborated with Orbia Fluorinated Solutions to optimize the high-performance electrolyte containing OS3, allowing the cells to operate with long life in harsh environmental conditions.

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

Dr. Miki Oljaca, Head of Growth and Technology at Koura, said, “This application of OS3 represents a significant advance in lithium-ion electrolyte performance and capabilities and serves as a commercial validation of the benefits that OS3 offers in high performance lithium-ion cells. The energy density that Amprius achieves in these cells is far beyond anything commercially available,” added Dr. Oljaca. “OS3 provides stability in the most challenging electrolyte applications, and we are delighted to see Amprius applying it in their commercial airframes to achieve such high performance.”

Orbia’s fluoride solutions brand, Koura, is a fully integrated fluorine technology company currently executing 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 developed to improve the performance and safety of the next generation of Li-ion batteries in support of a renewable future.
