Keracel Announces Solid State Battery Ceramic Electrolyte Conductivity That Equals Standard Lithium Ion Batteries
KeraCel, launched by a team of veteran Silicon Valley executives that are building the next generation lithium ion battery, announces a new milestone in performance of solid state ceramic electrolytes.
SANTA CLARA, CALIF.: KeraCel, a world leader in the development of highly manufacturable solid-state lithium ion cells, announced a breakthrough in high performance ceramic electrolytes. Ceramic batteries do not require the addition of a separator layer, which is required in standard Lithium Ion Battery (LIB) cells. Using a proprietary manufacturing process technology, KeraCel has been able to produce ceramic electrolytes with conductivity that equals that of a LIB’s liquid electrolyte plus the required separator layer, which is in the 0.4mS/cm to 0.8mS/cm range.
“We are able to achieve 0.7mS/cm conductivity at room temp, with the ability to exceed 1.5mS/cm as we mature our process technology”, said Robert Bagheri, KeraCel’s CEO.
Additionally, using 3D print process technology, KeraCel is able to reduce the ceramic electrolyte thickness to 100um, with a longer-term target of getting to 15um. These advancements will allow KeraCel ceramic batteries to deliver 1200 Wh/l energy density, which is approximately two-three that of standard Lithium ion batteries, and very high C rates required by industrial and automotive applications.
KeraCel is bringing to market a next-generation Lithium-ion solid-state battery design and manufacturing method that will allow production of cells with ceramic-based electrolytes and lithium metal anodes to achieve energy densities 2-3 times greater, improved safety, and at a cost of less than 50%, when compared to Lithium Ion cells today. The manufacturing process will allow virtually any shape or size of cell to be built for a multitude of applications without changing equipment or tooling under software control.
