Amprius Technologies, US-based manufacturer of lithium-ion batteries, has released a new high energy cell for electric mobility uses.
The cell offers an energy density of 370Wh/kg, which extends the runtime of the battery. It delivers a high-power performance over 3000W/kg, according to Amprius.
The cell uses a proprietary silicon anode material system as part of Amprius’ existing SiCore product line. This delivers more energy and power performance to the single cell, it said.
The cell’s design supports high discharge rates of up to 10C without cooling and 15C with active cooling. Amprius said that will make for a quick delivery of power without compromising the battery’s runtime.
Amprius is selling this new cell for use in industries which require batteries that can handle higher demands of power, such as aviation, including drones.
It also is marketing the cell for usage in high-performance electric vehicles, where both endurance and a fast energy delivery is needed, it said.
Amprius, based in California, said it gave early access pre-production samples of 10Ah cells to six of their customers to enable real-world testing in the fourth quarter of 2024, and ensure the cell would be ready for launch.
Dr. Ionel Stefan, CTO of Amprius Technologies, said: “This SiCore cell is a significant technical breakthrough for the industry, achieving a level of power-to-energy ratio that we believe has not been seen at such high-energy density. This cell is not just about performance but about creating new power possibilities for high-demand applications.”
Dr Kang Sun, CEO of Amprius Technologies, said: “With its unparalleled power-to-energy performance and adaptability across industries, the new SiCore cell offers our customers more design options and capabilities. Backed by our strong manufacturing partnerships and capabilities, we believe this innovation positions Amprius to meet growing market demand while driving the widespread adoption of silicon anode technology in rapidly expanding industries.”
