Vacuum Deposition Process Boosts Performance of Lithium-Metal Anodes by SION POWER

In a significant breakthrough for the battery industry, Sion Power, a leading U.S.-based company, is making strides in lithium-metal anode technology. Tracy Kelley, the company's President and Chief Science Officer, believes that Sion Power's vacuum deposition method is the gold standard for thin lithium films.

This innovative process allows for the formation of ultra-thin and uniform films, as thin as 2-3 microns, setting Sion Power apart from its competitors. The process is scalable, ready to support commercial demand at gigawatt scale, positioning the company as a leader in the battery market.

The vacuum deposition method used by Sion Power also enhances cost efficiency by reducing material usage. This cost-effective approach, combined with the high-performance batteries it enables, provides a scalable path to high-performance batteries.

Sion Power's unique focus and maturity in lithium-metal deposition sets them apart from other companies, including equipment providers. The company has spent decades developing and refining a process optimized specifically for battery anodes.

The company's innovation has been validated through customer engagements, including detailed throughput and cost analyses. In customer testing, Sion Power's 5-micron films delivered twice the cycle life of comparable competitor materials.

The vacuum deposition process is currently in use for producing anodes in Sion Power's Licerion large-format battery cells manufactured in Tucson, Arizona. This process allows for the production of large-format battery cells, a significant advantage in the battery market.

Moreover, Sion Power's process enables engineered surface coatings that enhance lithium stability and performance, further setting a new standard in the battery market.

With these advancements, Sion Power is poised to revolutionise the battery industry, offering a U.S.-based solution ready to support commercial demand at gigawatt scale and positioning themselves as the leader in lithium-metal anode technology.
